How to change Web Mail Mta port

[rhostager]

How do I change the Web Mail Mta port: 25 to another port?

My purpose in this is to keep mail submitted by the Zimbra web client from being spam processed.

Thanks,

The web UI doesn't use port 25.

Search the forums for some details on stopping the outbound mail from being processed by the anti-spam system.

Under the administration panel for your mail server, MTA tab you will find:

Web mail MTA Port: 25

Which is the port that the Zimbra web client SENDS the email to Postfix on. This is what I want to change.

Oh that port, sorry. Have a look in the wiki (and in the forums), there's details on setting an alternate listening port.

Thanks Bill,

I did search the Wiki and Forums and already have Postfix setup to LISTEN on port 587 (submission port). The piece of the puzzle I cannot find is how to make the Zimbra web client TALK on port 587.

Doing this separates the Zimbra web client from other port 25 traffic and allows you to treat it differently -- bypass spam checking.

I already used this to bypass spam checking on my ssl authenticated clients (Thunderbird, Outlook, etc.).

MarcMac posted that this is possible for the web client but did not give details.

Any help would be appreciated,

Has anybody determined how to do this yet?
