MAU Causing Relay Errors on Email?

carlosinfl · 01-23-2008, 07:18 PM

Using Postfix (MTA), Dovecot, & Spamassassin on my Debian email server.

I can receive email all day long no problem. I can log in as any user on the mail server in CLI and use the mail foo@foo.com command to send email fine. They other person gets the message. I then login to web mail and send email using Squirrelmail and it works.

Now when I load Thunderbird, I get email fine however when I send email, I get a error that says:

"The mail server responded 5.7.1.
<destination@domain.com>: Relay Access denied. Please check messg. recipients and try again."

I turned off Spamassassin and reloaded Postfix and Dovecot and nothing works. I only have this error sending in an email client set up for IMAP. Webmail and sending direct email from the server are no problems.

I checked /var/log/mail.err

Code:

swordfish:~# cat /var/log/mail.err
Jan 20 15:57:32 swordfish postfix/postfix-script: fatal: usage: postfix start (or stop, reload, abort, flush, check, set-permissions, upgrade-configuration)
Jan 20 22:21:46 swordfish spamc[6513]: connect(AF_INET) to spamd at 127.0.0.1 failed, retrying (#1 of 3): Connection refused
Jan 20 22:21:47 swordfish spamc[6513]: connect(AF_INET) to spamd at 127.0.0.1 failed, retrying (#2 of 3): Connection refused
Jan 20 22:21:48 swordfish spamc[6513]: connect(AF_INET) to spamd at 127.0.0.1 failed, retrying (#3 of 3): Connection refused
Jan 20 22:21:49 swordfish spamc[6513]: connection attempt to spamd aborted after 3 retries

Nothing else is listed...

With my ISP I had to use their outgoing mail server and use my incoming mail server. Different setup, but same error message.

That makes no sense to me. If I can send via Postfix and I can send via Webmail from the same network, why would my ISP then require me to use their outgoing server when using a email client like Thunderbird or Evolution. I would assume this is a IMAP error or something related to Dovecot or I would have the same error all around...no?

When you fire up Evolution, is it on the same machine or over the network? Sounds to me like Postfix is accepting mail from localhost but not from the network.

Check mynetworks in main.cf

The email server is on my DMZ (192.168.3.x) & the machine I try and send email from is my green LAN (192.168.1.x). I will check mynetworks however nothing on main.cf has changed and it worked before...

You didn't bother to mention that you had a working setup before. What exactly did you change to break things?

carlosinfl · 01-24-2008, 07:53 PM

I added SA (Spamassassin) however I stopped that service and removed the two entries it had me add in master.cf and reloaded postfix = still not working. Beyond that nothing. I just feel it has to be Dovecot because if Squirrelmail and POSTFIX let me send outbound email however when I use a client setup for IMAP, I get the error.
