Hi everyone,


we're planning on installing automx2 and some questions arose, maybe 
someone here is able to help.

We are working with multiple maildomains that all run on the same 
server, so we would set up an A-Record for autoconfig.example.com and 
use a CNAME to this for any further domains like autoconfig.domain.com.

Should both domains be listed in the automx2 database, even though they 
point to the same server? Or would it suffice if Thunderbird asks 
example.com for data?

What we couldn't find in the documentation either, was how to configure 
ports and encryption in automx2.

Any help would be highly appreciated!


Thanks,

Alex

While Thunderbird uses DNS lookups to resolve autoconfig.example.com,
automx2 does not use DNS lookups to determine which server names need to
be returned. It will only answer requests based on DB content.

Each domain must be listed separately in the database. The same goes for
each unique server. You can then associate servers with multiple domains
by creating entries in the "*server_domain" tables, i.e. use classic
many-to-many relationships.
