Port 587 is the best alternative because it is defined as the submission port.

To do this:

1) Add the line

  LISTEN_PORT=587

to

  ~scalix/sys/smtpd.cfg

2) Restart the relay:

  omoff -d 0 smtpd
  omon smtpd

3) Tell your internet standards-based clients (pop, imap, smtp) to connect to port 587 instead of 25.

For Scalix 11

Edit this line in the file /var/opt/scalix/NN/s/sys, where "NN" is your node name.

[SUBMIT]
LISTEN=192.168.1.23:587

Change to your ip address accordingly, then restart omsmtpd

# omoff -d0 smtpd ; omon smtpd

To verify,

# lsof -i 587

OR

# netstat -ntlp

You should be seeing port 587 is listening.
