DBMail currently allows catch-all addresses in the alias table, in the form of:
@domain.com
While this is a very nice feature, it would be very convenient to have aliases also in the form of: user@
which would allow for things like:
postmaster@domain1.com postmaster@domain2.com postmaster@domain3.com
to be handled by one alias table entry of postmaster@.
This would be VERY useful in a multi-domain environment. This alias could then forward to an existing mailbox and keep the administrator from having to enter the required postmaster addresses every time they create a domain.
Note: this can be achieved by Postfix with the following code:
main.cf:
virtual_alias_maps = pcre:/etc/postfix/valias.pcre
valias.pcre:
/^abuse@.+/i "abuse@ourdomain.com" /^postmaster@.+$/i "support@ourdomain.com"
