Apache - same subdomain on multiple domains

hi,

Is there a way in apache to have the same subdomain on multiple domains point to the same doc root without having to have a virtualhost directive for each domain.
I am hosting multiple domains on the same server with the same subdomain names - mail.domain1.com & cloud.domain1.com, mail.domain2.com & cloud.domain2.com, mail.domain3.com & cloud.domain3.com etc and want all the mail subdomains to point to /opt/webmail/ and all the cloud subdomains to point to /opt/cloud/. I have tried the below but it doesnt work.

Code:

<VirtualHost *:443> 
  Servername mail.domain1.com
  ServerAlias mail.* 
  DocumentRoot /opt/webmail 
</VirtualHost> 

<VirtualHost *:443>
  Servername cloud.domain1.com 
  ServerAlias cloud.* 
  DocumentRoot /opt/cloud 
</VirtualHost> 

I would like something that i dont have to touch again even if i add/remove domains - any ideas how i can do this ?

thanks

 

Code:

<VirtualHost *:443> 
Servername mail.domain1.com
ServerAlias mail.domain2.com
ServerAlias mail.domain3.com
DocumentRoot /opt/webmail 
</VirtualHost> 

<VirtualHost *:443>
Servername cloud.domain1.com 
ServerAlias cloud.domain2.com
ServerAlias cloud.domain3.com  
DocumentRoot /opt/cloud 
</VirtualHost> 

 

Thanks for the reply, however this is basically what i have now, except i have:

Code:

<VirtualHost *:443> 
  Servername mail.domain1.com
  ServerAlias mail.domain2.com mail.domain3.com
  DocumentRoot /opt/webmail 
</VirtualHost> 

<VirtualHost *:443>
  Servername cloud.domain1.com 
  ServerAlias cloud.domain2.com cloud.domain3.com  
  DocumentRoot /opt/cloud 
</VirtualHost>

I dont want to have to add to the serveralias line everytime i add a new domain, or remove from serveralias everytime i delete a domain.

I am trying to do something where i dont have to add/delete when i add or remove domains, just set it up once with wildcards or whatever and it works with all domains.

 

i don't think that the wildcard works after the subdomain
