Verizon blocking e-mail


mglas

Recommended Posts

I am have a problem with Verizon customers - they all have their e-mails rejected (new customer registrations, password resets, order information), etc. with a 550 error - telling me that I am not authorized to send mail to verizon.

 

Anyone else seen this? I am sending from the US to the US (in most cases).

 

Thanks

Make sure you enter your domain name without the "www" or you'll get a no records found every time.

Just between us, remember there are only 10 kinds of people in the world; those who understand binary and those who don't!!

I was not blacklisted.

 

I did take a look at the catalog side email class and noticed that it was not adding a Reply-To the the SMTP headers. I added one in and now it appears that the verizon mail is getting through.

Hi Michael,

I have been trying to solve this same problem for months... and just found the answer this evening.

emails from our website were not going through to Verizon, also aol, etc. Reason was that the name of the hosting server is different from the site's name. The Returnpath field in the headers kept showing the hosting server name (anonymous@hosting_server.com) which did not agree with the "From" field... so the big ISP's drop the email

I first tested that theory and found that changing my site's Full Host Name (my site is on a dedicated server) made the Returnpath field change and sure enough the emails from the website sailed through to Verizon no problemo. I wanted to keep the old servername though so that other domains hosted on our server could also send emails succesfully... so I kept digging.

Some wonderful person from our server company (Data393) sent me an email link to some good php info... I ultimately needed only to add the following three lines towards the end of "application_top.php" in the "store/includes" folder and also in the "store/admin/includes" folder:

 

putenv ("QMAILUSER=user");

putenv ("QMAILNAME=domain_name");

putenv ("QMAILHOST=domain_name.com");

 

That did it... the returnpath on the emails generated by the site now show "domain_name <user@domain_name.com>" and the emails are coming through to my Verizon.net email addrdess ! Thank God this one is solved.

Britt, is that fix just for QMail users - I'm in the same boat, I have a dedicated box but my mailboxes are still on my webspace reseller account, therefore reverse DNS doesn't match etc etc.

 

My issue is with AOL and I've applied the AOL Email fix found elswhere in the Forum.

 

The issue is sending mail from one box where the domain name mail records point to another.

 

I'm on Windows 2003 SMTP service for outgoing mail from the site.

 

Any thoughts?
