Re: Sendmail question
Thanks to the people who responded for their ideas. Where I think we will go with this is indeed using tools for virtual domains. In particular, if we can be sure doing so will leave mail to valid addresses untouched, making an entry to virtusertable sounds like the approach that will have least impact. I may do a test system to verify.

True, but it means about three years worth of former employees, some of whom we've probably forgotten. And then there is the issue of senders guessing e-mail addresses--while the way we assign addresses is probably not exactly intuitive for some of our colleagues. >Bill Stuart Biggerstaff Linda Hall Library 5109 Cherry Kansas City, MO 64110 Phone: (816) 926-8748 (800) 662-1545 x748 FAX:(816) 926-8785 URL:www.lindahall.org ___ Linux-users mailing list Archives, Digests, etc at http://linux.nf/mailman/listinfo/linux-users

I don't do sendmail, but did see an /etc/maildomains file on a system I did some other work on which provides for mapping mail for multiple domains with default addresses if there isn't a match. The file for this is in the format: [EMAIL PROTECTED] some_valid_email_address [EMAIL PROTECTED] another_valid_email_address example.com an_address_where_anything_else_goes. I thought this was a pretty neat way to handle virtual domains, and implemented this in smail-3.2 using the rewrite driver. This probably isn't the best way to handle several thousand primary addresses on a system though. It lends itself best to virtual domains with limited numbers of users. This could be used though if one has a capability similar to smail's smart_user variable which will forward unknown local addresses to another mail server for handling (or another instance of the server on the same machine, but listening on another NIC). >I know we could set up aliases for deleted former users and maybe for >incorrect spellings we could anticipate, but that wouldn't get all >possibilities.

Sendmail question
Is there a straightforward way to have e-mail sent to nonexistent addresses forwarded to root or another account? We would like to be able to collect these to possibly forward to the users. I know we could set up aliases for deleted former users and maybe for incorrect spellings we could anticipate, but that wouldn't get all possibilities. Any suggestion would be appreciated.
