My previous posting regarding smtp port 25 blocked by tmnet where TM will block OUTBOUND Simple Mail Transfer Protocol (SMTP) traffic or port 25 for all outgoing e-mails from streamyx dynamic IP addresses.

For those running qmail server, this is the way how to configure qmail-smtpd to listen on another port 587 instead of default port 25. In other word qmail-smtpd will listen on 2 different ports, 25 and 587.

First we copy /var/qmail/supervise/qmail-smtpd to /var/qmail/supervise/qmail-smtpd2 and edit the run script located in the qmail-smtpd2 directory and change the smtp port to 587.

# cd /var/qmail/supervise
# cp -rf qmail-smtpd qmail-smtpd2
# cd qmail-smtpd2
# vi run
