Tipped by MSeng See Profile
AT&T users over the last week started noticing that they were receiving significantly less spam in their inboxes thanks to a new spam filter. They then started noticing they were receiving significantly less mail, too. Users say that AT&T techs appear to be aware of the problem. We've fired off an inquiry to AT&T for an official explanation. Meanwhile, there's a scuff up brewing over the fact that Yahoo's "unlimited" e-mail does in fact have very real limits.

Email Munged?

Not to stray off topic, but does anyone have weird issues with Verizon email? We were inserting a URL into our emails and when it would come thru Verizon's email, the URL was changed!! We didn't try AT&T, but virtually every other ISP left the URL untouched. Very frustrating!

As a comcast user, welcome to the club.

Nothing new for me. As a comcast user, I have spam filtering turned off, yet comcast does not allow some legit email in. Example, for the past few months, I cannot receive emails from redbox (rental and charge card confirmations.) And, comcast won't fix it.

I was wondering why my spam folder was only getting about 5 or so messages per day for the last few days. Prior to that I was getting 50 - 100 per day. I kind of like it

Yahoo also dropping legit mail

Yahoo is also having their problems delivering legit mail. Apparently they've implemented some sort of greylisting. Yahoo is greylisting email and not delivering (bouncing) the email with a 451 "temporarily deferred" error message.

Re: Yahoo also dropping legit mail

Well, you won't really know. Both of my main accounts and all but one of seven subaccounts were completely down over the weekend with the mysterious "unexpected server disconnect" error. No POP3 access at all, and webmail had nothing.

They've let the five year olds loose in the datacenter again. Just once I'd like to see them do something right the first time.

I did a test last night with my sbcglobal.net account and my dslr.net account. So far it has received and sent messages that I have sent so far.

I dunno if that is any indication of e-mails I don't get but the majority that sit in my primary sbcglobal.net account were SPAM anyway. I abandoned that address a little over 2 years ago due to spam.

If the delivering mail server is configured correctly, the mail WILL go through.

Everyone in this forum can disagree, but it is only mis-configured mail servers being rejected - period! You can bet your life on it.

They are not grey listing anything. They are doing a DNS check and if the mail servers MX and/or A records are improper, they are rejecting the connection.

I think it is great. If we want to stop spam then we have to enforce the rules (RFC'S) setup for mail services. It is such a simple procedure to follow, no mail server should have trouble being compliant. They just have gotten away with it for so long but now mail servers are trying to clean up the Internet. So mail servers are going to have to be compliant.

Bullshit. I have 6 domains hosted with HostGator who are at constant battle with Yahoo to have their email delivered. I think HostGator probably has a clue about running email servers. There's a huge thread about this issue in HostGator's support forums, which I don't think is available to the general public, only those who have domains hosted by them.


Greylisting does exactly that . . . "temporarily rejecting" any email from a sender it does not recognize. But for some reason . . . it appears Yahoo is permanently rejecting legitimate mail.

From Yahoo themselves . . .

quote:
This is from the Yahoo site:

If your mail servers were experiencing persistent connection deferrals (with a 421 4.7.0 [TS0*] error code) when trying to deliver emails to Yahoo! Mail during the month of February 2008, please be assured that we have made recent and significant adjustments to our mail systems to address this issue. As a result, we believe that most of the deferral behavior is on the decline.

If you do continue to experience delivery problems, please review the Postmaster Help pages and report any continuing problems through our "Contact Us" forms.

Thank you for your understanding and patience during this time.

Rejected E-mail from improperly configured servers!

Like I stated in an earlier post, the only e-mails being rejected are from mail servers that do not follow the RFC's. They do not have the proper MX and/or A records setup. Anyone setting up a mail server has the responsibility to follow the rules. I'm all for the actions AT&T have taken to help stop spam.

When I implemented the DNS checking on my mail server it blocked 80% of the junk mail.

Mail admins need to do it right or don't do it at all!

Re: Rejected E-mail from improperly configured servers!

I run the same mail server yahoo runs - Zimbra. And I know how it behaves and know what happened when I implemented them DNS checks in my mail server. It shut down a lot of spam plus blocked mail that was coming through that was not spam, just from improperly configured servers. I guarantee you this is what is happening.

Re: Rejected E-mail from improperly configured servers!

One of the most amazing facts was the number of large companies whose IT departments are obviously not up to the challenge of administering their mail servers. When a mail server answers the helo command and it is not what the MX record shows or may not even have an MX or A record, it is rejected. It is such an easy thing to get right and spelled out in the RFC's.

I'm also an AT&T Yahoo! customer who has been putting up with this absurdity and I can assure you that a fairly good sample of emails being bounced are fully RFC compliant. I know enough about setting up a mail server, DNS and how it all works to know incompetence when I see it.

Not Crazy

@swbell.net

Eaten Mail

I am also experiencing the problem. For those of you that have not noticed the loss of legitimate e-mail: you will have no way of knowing unless your friends or business acquaintances let you know. The problem has been significant for me because e-mail from banks, airlines and educational institutions have been blocked from getting to me. They need to take out the new filters. Getting a box full of spam is better for me than not getting one necessary e-mail. ATT has spent the last ten days trying to tell me I am crazy over and over again. I am glad to find out I am not alone. The next step is to fix it.

disconnected

@snet.net

Fortunately, I still have an Earthlink e-mail address

..because when my clients who are using mags.net as their ISP can't send me mail for the past couple of months, I have them resend to my EL address and it comes right through. I've missed countless e-mails in the past 4-5 months with the SBCGLobal.net address of AT&T.

factchecker

@cox.net

No fan of ATT

But I'll given them thumbs up for at least giving users the option to filter out spam.

No spam filter is perfect and ATT is apparently learning this the hard way.

The Improved Spam and Filter Doesn't Work

Last night I made 4 reservations at the National Park Service.
Here is the results of their filters:
First Reservation Confirmation - Delivered to Spam inbox
Second Reservation Confirmation - Filtered, never received
Third Reservation Confirmation - Delivered to Inbox
Fourth Reservation Confirmation - Delivered to Spam inbox

They were all sent from the same smtp server and had the same addresses. It obviously is confused, pass some, spam inbox some, and just plain filter it so it isn't received. At least make it consistent, maybe even make it work as it should.

switch to gmail...

I already use gmail for a lot of mail, but have kept my original pacbell.net (before yahoo, before at&t) address as my main address for friends, family, and some business. I noticed the other day that the flood of spam I usually get disappeared. But so did legit letters from my sister who called me to ask why I didn't respond. I think I'll just abandon my ISP email and go through gmail instead.

Stopping spam.

Everyone complains about spam. But as soon as their mail server enforces the rules laid down for mail servers to help with the proble, they start crying.

Go to the people whose mail is being blocked, tell them to follow the RFC's issued for mail servers and their mail will come through just fine.

If they can't take the responsibility to setup their server correctly, they shouldn't set one up!

Re: Stopping spam.

It's not blind defense. I happen to manage three mail servers hosting several domains. I also manage DNS for those domains. I simply know how the system works, I have read the RFC's, and you can bet you will see other large mail providers start enforcing the RFC's in the same fashion.

I did not make the rules but I do try to follow them.

Have you read any of the RFC's regarding mail servers?

You can bash me and Yahoo and anyone else. They are just doing their job.

Splain me this then:

I have two ISPs, and one hosting company with POP mailboxes at each. Two of the ISPs are Covad resellers, one is a Qwest reseller.

The mailboxes on the Qwest hosted ISPs servers, where my domain/e-mail server are hosted, are rejecting all mail from all sources; i.e., the servers are bouncing all e-mail, period, including e-mail sent to my hosting company. All the e-mail servers at my hosting company are set up properly, and have been functioning properly for over a year. Now, they are fucked.

The mailboxes at one of the other ISPs (Covad ADSL reseller) is accepting all mail, and labeling some as SPAM, some as legitimate, and most e-mails are sorted correctly. No e-mail is being bounced as far as I can tell. This account has been functioning properly for five years or more. I haven't logged into the webmail during the last five days at this ISP to check, so I may be wrong.

The other ISP is an AT&T reseller, as well as a Covad reseller. My agreement with the ISP is for Covad ADSL service. That mailbox used to filter correctly with nary a miss; letting all legitimate e-mail through to my inbox, and correctly blocking all SPAM sending it to a SPAM folder on the server. I would clean the SPAM folder out regularly by logging into webmail. However, this ISP, over the last five days or so has completely fucked up all filtering, labeling and sending EVERY incoming e-mail to the SPAM folder. I have logged into webmail and attempted to retrain the SPAM filter by white-listing the non-SPAM e-mail, and deleting the true SPAM e-mail. This ISPs filters have responded by continuing to reject all e-mail as SPAM, white-listed, or not. This e-mail had been functioning properly for five years or more.

Something doesn't smell right. Does this nonsense have anything to do with AT&T copyright filtering implementations, the NSA's spying/filtering internet traffic, or is it just a bunch of FUCKED-UP ASSHOLES inadvertantly laying waste to small businesses who are dependent upon e-mail for their livelihood?

I used to get one or two SPAM e-mails delivered per day, along with a ton of legitimate business e-mail. Now, I get a few more SPAM e-mails, and NO BUSINESS E-MAIL!!!!!

Get used to it

EVERYONE filters, or just about. Almost every commercial server host filters email before it gets to you, so unless you are luck enough to find a honest host (lots of them lie and say the dont filter...cough...cough surpass...cough.cough) that doesnt filter your just going to have to live with the simple gods honest fact that there is no way email in inter current RFC iteration will ever again be 100% reliable.

Long Overdue

Hotmail and GMail have been doing the same for a long time. I rarely see spam on Gmail at all, and very little on Hotmail.

However, spammers are getting better at hijacking addresses. It's an eerie feeling to get spam from yourself.

I'm still waiting for the better mouse trap.

Who Cares if the E-Mails have the proper RFC configurations

If the only thing it takes to get through the filters is a proper E-Mail Server setup, then the spammers are going to do what it takes to make their message look legit.

This is a bunch of BS to block Legit E-Mail because someone at the other end does not know how to configure their server.

I did some test with some business associates and found that the same E-Mail would go to one of my non ATT account but got blocked by my ATT account (xxx.pacbell.net).

The customer service people at ATT either don't know about this new problem are are told to lie to their customers
