You are right. I'm sorry, I hadn't seen it. The Amavis issue is indeed included in the ISPConfig 3 FAQ as "How to disable spamfilter- and antivirus functions in ISPConfig 3"
. And it includes additional info, such as another line (receive_override_options = no_address_mappings) that also needs to be commented out when disabling Amavis so that Postfix checks virtual aliases. Thanks!
Another related point I mentioned I'm testing now is how to use ISPConfig to send mail, and Google Apps to receive it (filtering spam, etc.). With this configuration, emails sent between accounts in the same domain weren't being received, naturally because they don't go out of my server to Google. I'm now trying a workaround with a subdomain alias in Google, as described in Emails local delivered with Postfix
. But the alias verification is taking time, it seems because of DNS propagation.
