Using Sendmail wildcard receipts /etc/mail/virtusertable

Question

I am trying to define wildcard receipts in SendMail, from what I read in this document http://www.sendmail.org/m4/features.html#virtusertable I understand that this would be a correct syntax inside /etc/mail/virtusertable

old+*@domain1.com   [email protected]
[email protected]  [email protected]

I would expect first rule to match a receipt like [email protected] but it doesn't. The second rule works ok so I assume that localdomains and similar things are all configured correctly, but how to match a wildcard like in first rule? Sending to [email protected] returns the "not such user" error.

Thank you.

Looks like by supporting wildcard receipts of this form in virtusertable: old+*@domain1.com [email protected] sendmail actually accepts emails sent to "[email protected]", "[email protected]", etc. So it will NOT accept without the plus: [email protected] — adrianTNT, Oct 04 '11 at 11:16

Yes. It doesn't and must not. + sign have special meaning in virtusertable

but how to match a wildcard like in first rule?

Any plussed address, in which + is part of localpart will be matched

If you want transform old*@domain1.com into old+*@domain1.com (for processing later in virtuser) you can use regex map in LOCAL_RULE_0 to rewrite Just tonote - debug sequences of virtusertable lookup using sendmail -d60.5 -bv [email protected]
