Block ip address for qmail pop3 access

theinternethost

Hi All,

I'm trying to block an ip address from accessing qmail-pop3 access.

Other than using iptables firewall is there some way to do this in qmail or tcpserver.

TIA
Regards
Ross

Hi Ross,

Yes, you can block an IP from pop3 access similar to the way you would block it from smtp access.

Use the -x flag with tcpserver and create a rules file.

Here is the line of your pop3 supervise run file to update:

/usr/local/bin/tcpserver -v -R -H -c 500 -x /etc/tcprules.d/qmail-pop3d.cdb -l 0 0 110 /var/qmail/bin/qmail-popup \

And then create the rules cdb file /etc/tcprules.d/qmail-pop3d.cdb

If you need more specific directions for either of those steps please let me know.

-Raymond
