Hi all,

Sorry if this question has been posted before. I have dug through the archives but haven't found any relevant answers to this question.

I am running Dovecot on a server that serves a number of (virtual) domains each with a number of (virtual) users.

To read mail I am providing a webmail client and have configured HTTPS connections using reverse DNS so that each domain has its own IP address and that each IP address gets mapped to a different virtual host. Each virtual host presents and HTTPS connection particular to their own domain using the SSL certificate for that domain so that each user only sees his or her own domain throughout.

Is it possible to configure Dovecot so that mail-clients like Thunderbird or Outlook can connect via the default port using their own domain (maybe also using reverse DNS) and be presented with an SSL connection particular to that domain (i.e. using that domains certificate)?

Any comments welcome.

Thanks in advance,

    -Mike

At this time, Dovecot does not support multiple SSL certificates. The only way to implement it (currently) would be to install multiple instances of Dovecot, listening on different IPs/ports.

You could use stunnel as well instead of multiple dovecots, the only disadvantage being that you lose the source IP address.
