Here's my current setup: all mail for my domain xxx@domain.com (where xxx is any valid user name, domain.com is my domain) is handled by my ISP, they drop it into my pop account, To: (and all other, as far as I can tell) header intact (envelope is gone, of course). I have it set up this way because my computer is not _always_ up so I don't want email to go directly to my server. I use: isp pop3 account -> fetchmail -> postfix -> lmtp -> sieve -> cyrus imap server (all this works, the email gets all the way to the user that is set up in fetchmail as receiver). What I like to do is redirect emails addressed to certain adresses to specific accounts on the machine (or possibly elsewhere), all emails to unknown addresses woudl still go to the local account that is set as receiver of pop3 emails. my question is: where is the most appropriate point to do this redirection? I guess it cannot be done in fetchmail so it's either postfix or sieve? I definitely do not want to do it in MUA, that's just wrong. comments appreciated (on any part of setup), TIA! erik --===============86203061330375963== Content-Type: message/rfc822 MIME-Version: 1.0 Date: Mon, 2 Dec 2002 19:57:22 -0800 From: Bill Kendrick <nbs@sonic.net> To: svlug@lists.svlug.org Subject: [svlug] Sean 'Shaleh' Perry speaking about Debian packaging in Davis Message-ID: <20021202195722.A17721@sonic.net> Content-Type: text/plain; charset=us-ascii MIME-Version: 1.0 Precedence: list Message: 2 Sean Perry, co-author of "lintian" and maintainer of over a dozen packages for Debian, will be doing a talk at the Linux Users' Group of Davis tomorrow (Tuesday, December 3rd). http://www.lugod.org/meeting/ Maps, directions, carpool info, etc. are available here: http://www.lugod.org/meeting/library/ -bill! pr@lugod.org http://www.lugod.org/ --===============86203061330375963== Content-Type: message/rfc822 MIME-Version: 1.0 Date: Mon, 2 Dec 2002 23:26:30 -0500 From: George Georgalis <georgw@galis.org> To: Erik Steffl <steffl@bigfoot.com> Cc: svlug@lists.svlug.org Subject: [svlug] Re: mail forwarding/redirecting Message-ID: <20021203042630.GR25947@trot.local> In-Reply-To: <3DEB90A6.6F464A5B@bigfoot.com> References: <3DEB90A6.6F464A5B@bigfoot.com> Content-Type: text/plain; charset=us-ascii MIME-Version: 1.0 Precedence: list Message: 3 On Mon, Dec 02, 2002 at 08:56:06AM -0800, Erik Steffl wrote: > just got a new domain registered and I would appreciate advices on how >to handle email redirecting.

Just use fetchmail to pop and set the mda to procmail which will make the decisions and deliver locally or use your postfix for remote deliveries... $ cat .fetchmailrc defaults mda "/usr/bin/formail -s /usr/bin/procmail" no rewrite preconnect "ssh -f galis@galis.org -L 11110:galis.org:110 sleep 9" poll localhost with protocol pop3 and port 11110: user xxxxx is delivery password xxxxxxxxx user xxxxx is delivery password xxxxxxxxx // George -- GEORGE GEORGALIS, System Admin/Architect cell: 347-451-8229 Security Services, Web, Mail, mailto:george@galis.org Multimedia, DB, DNS and Metrics. http://www.galis.org/george --===============86203061330375963== Content-Type: message/rfc822 MIME-Version: 1.0 Date: Tue, 3 Dec 2002 00:34:55 -0800 From: Vince Hoang <svlug@ml.altern8.net> To: svlug@lists.svlug.org Subject: Re: [svlug] mail forwarding/redirecting Message-ID: <20021203083455.GJ98677@anarchy.com> In-Reply-To: <20021203082008.GH98677@anarchy.com> References: <3DEB90A6.6F464A5B@bigfoot.com> <20021203082008.GH98677@anarchy.com> Content-Type: text/plain; charset=us-ascii MIME-Version: 1.0 Precedence: list Message: 4 On Mon, Dec 02, 2002 at 08:56:06AM -0800, Erik Steffl wrote: > all mail for my domain xxx@domain.com (where xxx is any valid > user name, domain.com is my domain) is handled by my ISP, they > drop it into my pop account, To: (and all other, as far as I > can tell) header intact (envelope is gone, of course).

If your ISP is clued and small, you can affordably get your ISP to relay your domain for you. When your machine is online, you send an ETRN to the mail relays queueing your mail. You can then route mail for your domain to your heart's content without any loss of envelope information. > I use: isp pop3 account -> fetchmail -> postfix -> lmtp -> > sieve -> cyrus imap server (all this works, the email gets all > the way to the user that is set up in fetchmail as receiver).

Is it reasonable to expect them to queue email for few hours? what about few days (extreme cases of troubles with dsl lines, only happened once so far)? I'll ask my ISP (rawbandwidth) but if you have more info/pointers I'd appreciate that so that I have some idea what I can ask of them... and last but not least - who sends ETRN? any pointers to more info (I'll search for it but again, I'd appreciate any pointers) thanks a lot, >> I use: isp pop3 account -> fetchmail -> postfix -> lmtp -> >>sieve -> cyrus imap server (all this works, the email gets all >>the way to the user that is set up in fetchmail as receiver). > > > Wow. hey, everything should be as simple as possible but not simpler:-) erik --===============86203061330375963== Content-Type: message/rfc822 MIME-Version: 1.0 Date: Tue, 03 Dec 2002 01:38:58 -0800 From: J C Lawrence <claw@kanga.nu> To: Erik Steffl <steffl@bigfoot.com> Cc: svlug@lists.svlug.org Subject: Re: [svlug] mail forwarding/redirecting Message-ID: <4330.1038908338@kanga.nu> In-Reply-To: Message from Erik Steffl <steffl@bigfoot.com> of "Mon, 02 Dec 2002 08:56:06 PST." <3DEB90A6.6F464A5B@bigfoot.com> References: <3DEB90A6.6F464A5B@bigfoot.com> Precedence: list Message: 6 MIME-Version: 1.0 On Mon, 02 Dec 2002 08:56:06 -0800 Erik Steffl <steffl@bigfoot.com> wrote: > all mail for my domain xxx@domain.com (where xxx is any valid user > name, domain.com is my domain) is handled by my ISP, they drop it into > my pop account, To: (and all other, as far as I can tell) header > intact (envelope is gone, of course).

Better: Get someone to MX for you and then ETRN all your mail from them when you are up. Simple, easy, efficient, and preserves envelopes. Or, if you really want to do it right, set up Taylor UUCP and have some one batch if for you. Fairly simply and easy, and does *everything* right. -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. claw@kanga.nu He lived as a devil, eh? http://www.kanga.nu/~claw/ Evil is a name of a foeman, as I live. --===============86203061330375963== Content-Type: message/rfc822 MIME-Version: 1.0 Date: Tue, 03 Dec 2002 01:42:05 -0800 From: J C Lawrence <claw@kanga.nu> To: Erik Steffl <steffl@bigfoot.com> Cc: svlug@lists.svlug.org Subject: Re: [svlug] mail forwarding/redirecting Message-ID: <4365.1038908525@kanga.nu> In-Reply-To: Message from Erik Steffl <steffl@bigfoot.com> of "Tue, 03 Dec 2002 00:54:04 PST." <3DEC712C.2030606@bigfoot.com> References: <3DEB90A6.6F464A5B@bigfoot.com> <20021203083455.GJ98677@anarchy.com> <3DEC712C.2030606@bigfoot.com> Precedence: list Message: 7 MIME-Version: 1.0 On Tue, 03 Dec 2002 00:54:04 -0800 Erik Steffl <steffl@bigfoot.com> wrote: > Is it reasonable to expect them to queue email for few hours? Yes. Historically the minimum bounce time was 4 days. More recently the loads of SPAM and a few other idiocies have moved that down to 2 days in a few cases. However, an obliging ISP (which really means any ISP or other service willing to run TERN delivery for you) will certainly do 4 days. > I'll ask my ISP (rawbandwidth) but if you have more info/pointers I'd > appreciate that so that I have some idea what I can ask of them...

So to avoid confusing people sending you E-mail, you will want to keep your mail server running or connect and send an ETRN within that threshold. Back before the DSL days, I used to recommend small business customers with static IPs running their own mail server to connect at least once an hour for good measure. -Vince ===
