PROBLEM
When trying to use SpamAssassin, it shows this error in /var/log/maillog:

host-foo spamd: spamd: connection from [ip address] at port 55390
spamd: unauthorized connection from [ipaddress]

ENVIRONMENT

• On-Premise Server + WebMail Installations: Version 6.0 > Current Version

CAUSE

On certain machines, you might not have a loopback address assigned. And when trying to use SpamAssassin, it shows this error in /var/log/maillog:

host-foo spamd: spamd: connection from [ip address] at port 55390
spamd: unauthorized connection from [ipaddress]

SpamAssassin usually binds to all the IP addresses on the machine, but you'll need to specify which IP addresses are allowed to be a client. If you have no loopback IPs configured, it detects your IP as a public IP.

RESOLUTION

1. Open up /etc/rc.d/atmailserver (or an equivalent)
2. Fnd this line:
   

   /usr/local/atmail/spamassassin/bin/spamd -d -x -q -u atmail --virtual-config-dir=/usr/local/atmail/ -m 6 -r /usr/local/atmail/spamassassin/spamd.pid

3. Change to:
   

   /usr/local/atmail/spamassassin/bin/spamd -A [public IP adddress] -d -x -q -u atmail --virtual-config-dir=/usr/local/atmail/ -m 6 -r /usr/local/atmail/spamassassin/spamd.pid

   Where [public IP address] is your IP address.
4. Restart Atmail.
   

   % /etc/init.d/atmailserver restart
