Possible BUG: 11.0.9 #MU55 - Apache Webmail Wildcard missing by default

[Antonio Sanchez]

I have detected a possible BUG in the default configuration of Plesk 11.0.9 at least in #MU55.

Working with the DNS Wildcard for Webmail I have found that the system does not create the ServerAlias Wildcard according to the DNS Zone in the Apache directives.

Recreate:
* Create a new domain with primary DNS zone
* Try to access to webmail.domain.tld. It must work correctly
* Try to access to whatever.webmail.domain.tld. It does not work and Plesk shows the default webpage.

Why?:
In Plesk 11 the Apache main directives are located under /etc/httpd/conf.d/. The main file that manage the vhost directives is zz010_psa_httpd.conf.

Into this file we can find that it points to another files, generated by Plesk, for example, when you reconfigure domains with /usr/local/psa/admin/bin/httpdmng --reconfigure-all

This is how zz010_psa_httpd.conf looks like:

#ATTENTION!
#
#DO NOT MODIFY THIS FILE BECAUSE IT WAS GENERATED AUTOMATICALLY,
#SO ALL YOUR CHANGES WILL BE LOST THE NEXT TIME THE FILE IS GENERATED.
Include '/usr/local/psa/admin/conf/generated/13735297540.77229700_server.include'
Include '/usr/local/psa/admin/conf/generated/13735297540.77229700_horde.include'
Include '/usr/local/psa/admin/conf/generated/13735297540.77229700_atmail.include'
Include '/usr/local/psa/admin/conf/vhosts_bootstrap.conf*'

As we can see the webmails config is located under the /usr/local/psa/admin/conf/generated/

Well, this is where the possible BUG exists becouse into these files a ServerAlias directive for the wildcard should be created but it is not.

As default it creates

ServerAlias webmail.domain.tld

And it should create:

ServerAlias webmail.domain.tld
ServerAlias *.webmail.domain.tld

Solution:
I think that in the /usr/local/psa/admin/conf/templates dir, where are located the files that has the configuration template info used to generate the correct configuration, are not defined the wildcard pointers in the ServerAlias, so creating this pointers will solve the problem

I hope this info could help anyone with this kind of problems.

Sorry but I do not understand why do you think that wildcard should be created mandatory with webmail ServerAlias?
If you need to use wildcard subdomains - use article http://kb.parallels.com/en/2239
If you need modify default vhost configurations template - use corresponding documentation - http://download1.parallels.com/Ples...linux-advanced-administration-guide/68693.htm

It is simple.

Plesk creates by default the *.webmail.domain.tld in the DNS zone becoming from Plesk default DNS templates.

Therefore, it would be normal to maintain a consistent configuration, if the wildcard is generated automatically when you create the DNS zone for a new domain, it would make sense that the Apache has a configuration able to function properly with this configuration. If at DNS level, domain pointers are created and Apache do not work with it, in my opinion is a BUG since it is a configuration inconsistency.

Looking to the DNS configuration it is expected that *.webmail.domain.tld works in Apache such a way that whatever.webmail.domain.tld answers with the webmail frontend.
