Hello,

Some of our clients travelling abroad have seen ports 993, 995, 465 and 587 (We keep 465 for old Outlook 2003 machines that will replaced sometime later this year) blocked.

Is there a way to make Dovecot simultaneously listen to ports 993 and 1993, ports 995 and 1995 and Postfix on ports ports 465 and 1465 , 587 and 1587 ?

In other words, have a secondary listener ports 1993, 1995, 1465 and 1587 for the above services ?

Thank you !

Dave

*) For Postfix, it's easy to achieve this by duplicate the settings in /etc/postfix/master.cf with a different port number.
*) But seems Dovecot cannot listen same service on multiple ports, you'd better ask in Dovecot mailing list.

BTW, will it be easier to overcome this block by setting up VPN for these users?
