Temporarily change IMAP port

[EnglishDude]

Hello all,

I want to migrate from my old mail server (Exim4 and uw-imapd). As I'm upgrading from Exim to Zimbra on the same server (I know this is not recommended but I have restrictions), I need to run uw-imapd so I can use some imapsync program to move emails over. The issue is that I can't figure out how to change uw-imapd's default port but I know Zimbra's default IMAP port is much easier to change, but I'm not quite sure how to do this - can someone suggest how to do this, so I can move my emails over than revert it back to default please?

Thanks very much for your help in advance.

Regards - Piers

Just found out how to do this and it's painfully simple. I am very embarrased for not finding this before, I apologise.

Thanks so much to everyone for all your help - it is much appreciated.
