Re: [RndTbl] Sendmail .mc file for forwarding server?
by gedetil＠cs.umanitoba.ca 06 May '03

I've got such a file, but it's full of RedHat-specific stuff too, so it won't do you much good as is. However, the trick to doing this is fairly simple, particularly if you're using the .mc macros. Just start off with one of the typical .mc source files, remove all MAILER definitions, and add the following instead... FEATURE(nullclient, host.to.forward.to)dnl ... where host.to.forward.to would be the fully qualified domain name of your internal mail server. The nullclient feature sets up special mailer definitions so that all mail, whether local or not, goes to the forwarding host.

[Posted to man.unix.general and other news groups] ------ Forwarded Article <b98k7d$qha$1(a)canopus.cc.umanitoba.ca> ------ From gedetil(a)cs.umanitoba.ca (Gilbert E. Detillieux) The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, May 13. The meeting topic for this month is as follows: Samba 3 Samba is a suite of programs that seamlessly provide SMB/CIFS file-and-print services to Windows clients. A robust and reliable implementation, it is now at version 2.2.8. What's in store for the future? In development now, and available for download for testing is version 3.0alpha. This version has many enhancements to the 2.x versions, including Active Directory support (this release is able to join a ADS realm as a member server and authenticate users using LDAP/Kerberos), Unicode support, better Windows 2000 printing support including publishing printer attributes in Active Directory, support for migrating from a Windows NT 4.0 domain, support for establishing trust relationships with Windows NT 4.0 domain controllers, and lots of other changes! Kevin McGregor will show you how to get started in testing this leading-edge technology. The group holds its general meetings at 7:30 PM on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our new meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15 PM, so the meeting can start promptly at 7:30 PM. Don't be late, or you may not get in. Limited parking is available for free on the street, or in a lot across Ellice from IBM, for $1.00 for the evening. Indoor parking is also available nearby, at Portage Place, for $2.00 for the evening. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Also note that MUUG maintains two mailing lists, called "muug-announce" and "roundtable". If you're not already on these lists, we encourage you to subscribe now: http://www.muug.mb.ca/mailman/listinfo/ The "muug-announce" list is used for monthly meeting announcements (such as this one) as well as other important announcements of interest to MUUG members. The "rountable" list is meant to be a forum for follow-ups to topics discussed at the meetings, or for round-table-style discussion on other topics that come up between meetings. Of course, for this to be effective, we need to reach a certain critical mass. So, please subscribe, and stay involved! -- Gilbert E.

Sendmail .mc file for forwarding server?
by Scott Balneaves 05 May '03

05 May '03

Does anyone have a .mc file kicking around for sendmail that creates a forwarding only server? I'd basically like to set up an OpenBSD 3.3 firewall box running the new spamd, and a sendmail daemon that basically forwards all mail received onto our internal mail server. I know I could write a pf rule that would forward port 25 to our internal mail server, but I like the chroot sendmail on OpenBSD, and would prefer to have it exposed to the big, bad innurnet.
