Hi,

Is it possible to catch e-mails, which are addressed to an invalid user on my domain and forward them to a mailbox.

Also, would it be possible to set up a return e-mail telling the sender that the user does not exist and that the e-mail is being reviewed by a member of staff. (ie. A custom postmaster message for any email which ends up in the `invalid user' mailbox.)

Currently hacking through the book & docs, but any info will be appreciated.

Thanks
Gavin.

Hi Gavin ,

Yeh its quite possible with a utility called procmail.
With RedHat Linux it comes pre installed but iam not sure about ur distribution.

It does what u want and lot more. There are numerous tutorial available on the internet whicj will guide u to accomplish ur task.

Hi Gavin ,

iam sending a few links for ur reference. Please check them out and see if they suit ur demands.

look procmail will help u in autoresponding to a particular account or on any other criteria that matches however ur MTA ( sendmail ) will by default reject unknown users so there is no way procmail will come into picture ( so no autoresponder !!!!!! )
so the first thing for u to do is setup ur mail server so that it will accept all email ( even if user does not exsist) and forward it to some local account on ur machine and then procmail comes into picture and does autoresponding part.

u can accomplish the allowing of mails to non local users by making changes in the /etc/aliases file or thru sendmail's various *table features.


Hope this eases a bit for u.
