We have clients that have ServerAlias *.example.com in their vhost.conf, so they can use mod_rewrite or other code to use 'virtual subdomains'. This used to work just fine under Plesk 8.6, but under Plesk 9.2.2 it seems that webmail.example.com is also catched by this ServerAlias, so webmail is effectively unreachable. I think this might have something to do with Horde config being in a separate file in /etc/httpd/conf.d/ and being loaded after the Plesk configuration.

Does anyone have an idea on how to be able to use virtual subdomains without explicitly listing all virtual subdomains (instead of *.example.com)? Listing them all individually is not an option for a number of customers as this list changes frequently.

Maybe try setting horde to load up before the plesk config?

The config files in /etc/httpd/conf.d/ are probably loaded in alfabetical order and yeah, these are the last two:

zz010_psa_httpd.conf
zzz_horde_vhost.conf

I could change one of these filenames to change the order, but that doesn't feel like a great and stable solution. Any change in Plesk will probably undo this, right?

Seems I'm not the only one having this problem: http://forum.parallels.com/showthread.php?t=91870

what about a symlink from 00_horde.conf to zzz_horde_vhost.conf ? That won't get overwritten and will get loaded first.

Sure, you'll get errors when zzz_horde(etc) then gets loaded twice, but maybe it will work anyway?

Of course maybe there's a reason why the plesk config has to load before the horde one

I know one sure fire way to find out!

The problem seems to be more general: the webmail subdomain for all domain aliases is not showing Horde, but the site. This looks like a bug in Plesk 9(.2.2). Others seeing this?
