This is one of the postfix config items we manage, so it's rewritten on startup. You'll want to edit the file /opt/zimbra/conf/postfix_recipient_restrictions.cf, which is a template for this config value. I'd add your value directly after permit_mynetworks. Then restart postfix.
The file is one value per line, with some substitution syntax that you don't need to worry about.
WARNING - this will get wiped out on upgrade (the .cf will be overwritten) so keep a copy somewhere. |
