Title: SME 7.1.3 Qmail FQDN problem causing SPAM listing in CBL
Post by: kangkc on June 12, 2007, 05:42:53 PM

Need some urgent advise as our public IP has been listed as SPAM source in cbl.abuseat.org resulting in mails being rejected in many recipients.

According to http://cbl.abuseat.org/qmailhelp.html on possible problem in Qmail configuration. I have found that both in /var/qmail/control/helohost and /var/qmail/control/me, the domain name is used instead of the FQDN of the SME server. This matches what is being described in the CBL possible cause.

Is there a quick fix for this? I would expect lots of you who are on 7.1.3 will have the same problem and get blacklisted in CBL.

Please help....

SMTP is handled by qpsmtpd. The FQDN is used via this templated config file:

# cat /var/service/qpsmtpd/config/smtpgreeting

Verify by issuing:

# telnet localhost 25

Or just do this...

config setprop smtpd Greeting 'Whatever you would like'
signal-event email-update

/var/service/qpsmtpd/config/smtpgreeting should contain your greeting

Then to check it out type...

telnet localhost smtp

You should attempt to find out exactly why rather than speculating.

Not by my reading of it. The domain name of your server should be neither a "generic" name, nor a bare hostname.

Send them email and ask. They say they will answer email promptly.
