Not exactly.
'mail' as hostname is not hard-coded anywhere. The OHN is hard-coded
into the WM/WC host headers, but the OHN has no naming restrictions
('webmail.example.com,' 'hosting.example.com,' et al., are used by our
clients). Yes, you might think would think that using the origin
'example.com' as the OHN would be fine. The OHN becomes the SMTP
banner name by default, so it should be the canonical name of the box;
generally speaking, you'd be on the honor system for making them match
up (except with a really picky RBL). But if you're using Web Messaging
or Web Calendaring (and particularly if you're using both), a
corresponding A record pointing to the IMail server becomes mandatory
for web navigation because the OHN becomes the root of URLs.
As a consequence of changing the OHN, default Reply-To: addresses
change as well. Modifying the Reply-To: as part of an automated and/or
batch user creation routine is clearly doable, and I don't think it's
a wail-worthy problem. When using the GUI to add a user ad hoc, it is
another step to remember, admittedly.
With the recent change that allowed the SMTP banner to be
RFC-compliant, it became possible to put the canonical name in the
banner, even if the cn was not equivalent to the OHN. This was
tantalizing. But that hasn't solved the WM/WC issue, so you still need
to follow the directions. Hopefully, this will be parameterized in
WM/WC at some point soon.
