I have Spamdyke running on the box currently. I have spam filtered through spamhaus.org according to

The /var/qmail/control/blacklists file isn't used when spamdyke is
installed. The default configuration (created by qtp-install-spamdyke) is:
check-dnsrbl=zen.spamhaus.org
check-dnsrbl=bl.spamcop.net
so you're probably using spamcop as well.
What's odd is it doesn't matter where the client is, the connection gets refused. Squirrelmail works fine so I know on the localhost its running smoothly.
Sounds like private addresses are being denied. Did you upgrade
recently? If so, spamdyke probably isn't running any more. An upgrade to
the qmail-toaster package will effectively disable it.
# cd /var/qmail/supervise/smtp
# ln -sf run.spamdyke run
will fix it.
I checked under /etc/spamdyke and checked the black list settings there. The
blacklist files have nothing listed.

Good suggestion. In general, you should either use port 587 for
submissions, or use spamdyke (which bypasses rbl checks for
authenticated users). You can alter your tcp.smtp file to define an open
relay for your private network, but that solution is risky (not very
secure), especially with windoze hosts on your private network.

Hello all,
I’m having an issue I have yet to figure out. About a week or so ago my
server stopped accepting incoming connections to send mail. I checked
my router/firewall/port forwarding settings and all was correct. So I
went inside our network (origionally the client was outside) and
attempted to connect/send mail. Same error from client, unable to
connect to mail server. So I attempted to telnet to both the external
IP and internal IP addresses. Connection refused (using putty).
I checked the logs after that and don’t see any reference to any IP
address attempting to connect to port 25. I checked to see if IP tables
had somehow been enabled on the machine. Nothing. I then checked for
SELinux and ran nmap localhost and nmap /Domain/ as well as nmap
/hostname/. It says port 25 is open and taking requests yet I get
connection refused at any location.
To make things interesting, I’m able to email to any address that server
holds. Just can’t reply/send out from any address the server holds.
Any thoughts where I could look? The logs don’t even show an attempted
connection.
