You should find the following lines in the /opt/zimbra/postfix/conf/master.cf:

#submission inet n      -       n       -       -       smtpd

#	-o smtpd_etrn_restrictions=reject

#	-o smtpd_client_restrictions=permit_sasl_authenticated,reject

uncomment them (maintaining the white space at the beginning of lines two & three) then restart postfix. You'll need to make this modification after each upgrade of Zimbra. There's also an RFE in bugzilla for this feature to persist and be enabled by default, search and vote for it.
You should also upgrade to the most recent ZImbra release.

Bill, would this work too in order to run another SMTP daemon on port 8025 (for example).
As you might know, some ISP here are forbidding their users to use an "external" SMTP server (ie not the ISP SMTP server) on port 25...

I assume you mean inbound to the zimbra server? If you do then, yes, it's possible. If you look at the master.conf file you'll see that it already listens on port 465 but you can add another port if required.

Tried updating /opt/zimbra/postfix/conf/master.cf by hand but got overwritten when i restarted the service. I'm currently using
Release 7.1.1_GA_3196.UBUNTU10_64 UBUNTU10_64 FOSS edition.

Make the changes to /opt/zimbra/postfix/conf/master.cf.in. Make sure to save a copy as they won't be preserved between upgrades.

Thanks Brian, it worked
