[PATCH] Support for more than one exchange server in mail/davmail port

[José García Juanino]

Hi FreeBSD ports,

please could any port committer take a look at 218140 PR?. It submits
a patch to support more than one exchange server to connect. Today
Microsoft Exchange servers are more and more popular.

The patch is pretty similar to postgresql server databases port, and
works fine at least for me.

Thank you for your support, best regards.
