550 Sender verify failed
 
On a new setup, I get this as part of a bounce message when trying to send mail from the webmail, does anyone know what I'd need to do or where I'd need to start to fix this?

Thanx

Allen

(error message follows:)

Please set the correct sender address under options in the webmail program.

Thanks, and I've tried setting my options in webmail prior to sending, but I am still getting errors when I send to some, but not all domains:

Final-Recipient: rfc822; customerservice@oncall-pc.com
Original-Recipient: rfc822;customerservice@oncall-pc.com
Action: failed
Status: 5.0.0

to ajackson@solutionsforcare.org. The account or domain may not exist,

How do I allow a distant mail server to verify sender's validity? I get the feeling that this is some anti-spam measure that I'm up against...

Thanx

Allen

Trying to dissect that error message:
Diagnostic-Code: smtp; 550-Verification failed for
<ajackson@solutionsforcare.org> 550-The mail server could not deliver mail
to ajackson@solutionsforcare.org. The account or domain may not exist,
they may be blacklisted, or missing the proper dns entries. 550 Sender
verify failed

I know that the domain exists, I can ping it, and I can browse it, and I can dig it.

How do I tell if that domain has been blacklisted, and more importantly, how do I change that? If this is a dns issue, then I can only guess that it is a reverse DNS lookup that may be failing, since I can ping/browse/dig by name, but how do I check and/or fix that too?

Thanks,

Allen

I guess the others erver tries to verify your sender address and that fails. Are you able to send an email to yourself from outside?

Allen15 10th February 2009 05:01

I cannot receive any mail from outside the domain, but I can send mail <from my ISPConfig-created site & webmail> to any domain that doesn't try to verify the sender.

For whatever reason, the user I created is not allowed to receive email? (I sense another wipe and reload session coming on, but I've gotten fast enough doing it that I no longer dread it *as much* ...)

ok, then thats the problem waht you have to fix. send yourself an email and check the mail log for errors.

Allen15 11th February 2009 21:17

I guess I really don't know where to start looking for such a "mail log" -- which mail (server?) or client should I be looking at, the sender or the recipient, and if it is somewhere on my ISPConfig installation, where and/or which file should I be trying to read?

I am running Ubuntu 8.10 from the perfect server install and ISPConfig 2.2.29, if that helps?

Thanx,

Allen

(To clarify, should I be looking for some log in ISPConfig, or in my host Ubuntu server logs, or at a log of whichever mail client or server that I am externally trying to send from and failing? (I don't have complete access to many of the external server logs, as they are managed from various ISPs or otherwise, like Yahoo!, etc.)

till 12th February 2009 10:25

The sender and recipient server are normally the same if you send yourself an email. the log files of a linux system are in /var/log

Allen15 12th February 2009 16:38

I was afraid someone would say that...

If I log into the control panel for ISPConfig and then go to the webmail interface, I can send myself an email and get it with no problems.

It is only when I try to send an email to an external domain that I am getting that sender verification error, and further more, if I try to send email from an external domain, I am unable to receive it on the ISPConfig-based system, even if sent as a reply to a message I was able to get externally.

No external domain is able to send email to me at the ISPConfig box, and any external domain mail server which does sender verification will refuse all further connections after that fails, so I cannot send mail to them from ISPConfig system.

I really had higher hopes and plans for this system than a glorified intra-net IM system, but that is currently all it will reliably do (email-wise).

Code:

root@www:/var/www/www.solutionsforcare.org# ls -l /var/log/mail*
-rw-r----- 1 syslog adm      0 2009-02-05 22:41 /var/log/mail.err

I get no hits in the mail log when sending from an external domain that does sender verification to indicate that anything has happened at all.
