sendmail: how to wildcard hostnames in virtusertable or genericstable?

duanekimball · 06-01-2018, 09:28 AM

I work for a big company and we have many host that follow a naming convention.

What we do now, is handle each email for the server based on its function
@dns001.bigcompany.com dns-admin
@dns002.bigcompany.com dns-admin
@dns003.bigcompany.com dns-admin
@dns004.bigcompany.com dns-admin
@mail001.bigcompany.com mail-admin
@mail002.bigcompany.com mail-admin
.
.
@mail321.bigcompany.com mail-admin
@logger001.bigcompany.com log-admin
...and so forth
where: dns-admin, mail-admin, log-admin are /etc/mail/aliases

We're running 8.14.4 on our mail relay hub (redhad 6) that gets email from 100's of these boxes and currently we just have to add/delete lines to the /etc/mail files as hosts are (mostly) added and deleted

We just want something simple like:
@dns*.bigcompany.com dns-admin
@mail*.bigcompany.com mail-admin
@logger*.bigcompany.com log-admin

thanks!

Do you have sendmail's source installed on your system? If not, you can get it free @sendmail.org. cf/README explains this clearly.

You can use procmail to filter mail based on ^TO and using wildcards for the domain part.
Something like the following (untested) in /etc/procmailrc:

Code:

:0
* ^TO.*@dns[0-9].bigcompany.com
! dns-admin
:0
* ^TO.*@mail[0-9].bigcompany.com
! mail-admin

I didn't see anything about wildcarding the RHS of an email address. I tried the +* trick in the generics or virtuals..no luck. I think that only works with the username and then for mailertable entries, which doesn't meet my needs

If you've read cf/README and can't find what you want I don't understand your question. You can ask at comp.mail.sendmail; be prepared for Mr Claus Aßmann's reply.
