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"
