Using wildcards in virtusertable for sendmail: resources, pointers, and simple examples, please.

Using wildcards in virtusertable for sendmail: resources, pointers, and simple examples, please. Google-fu fails to provide examples that answer my questions. [emm eye]

While the basic question, "Can I use wildcarded addresses at the server level with sendmail?" leads to the answer "of course, using vitusertable," the examples generally seen have broad scope:


[e-mail] -> [e-mail]


Compounding this is the sendmail-specific wildcarding scheme, which I still don't completely grok.

can I wildcard something like this?

[*+]foo[*+]@mydomain.com -> [e-mail]

(please note my also-primitive grasp of grep may mislead. I'm hoping that pseudo-address translates verbally to "any number and combination of characters on either or both sides of a specific string.")

So I think there are two parts here.

1. can I use virtusertable to set up subset-catchalls and direct them to the same domain?

2. can I get grep-style (grep-ish, what have you) wildcarding in virtusertable?

TIA!

"regular expressions" is the phrase you want to search on, rather than "grep-style wildcarding".

By "[*+]foo[*+]" I'd guess you mean ".*foo.*"

Anyway, I don't know sendmail, sorry. Switched to postfix long ago, which apparently supports regular expressions in aliases, which would probably do what you want.

I've never heard of being able to use regex's in virtusertable personally. As for the example:
[e-mail] -> [e-mail]

That means that myemail@some will get sent to myemail@other, joe@some will get sent to joe@other, etc.. As for the catchall question, can you explain that a bit more? Not sure what you mean by subset catchalls, if you could explain that a bit more, and what you're trying to do, I might be able to help..
