I sent mails using mutt. the from e-mail is like: laur...@host.domain.com Because laur...@domain.com would refer to me on any dedicated server from that domain. Do you think it can come from that configuration ? Thank you Mike ;) L

Yes, basically you can just invoke 'sendmail b...@domain.etc' and type message with all the headers you need - 'to:', 'from:', 'subject:' etc to stdin.

For MTA: it involves installing a DNS server ? Not really. Your IP belongs to an ISP, and it's DNS server has the authority for that address. So, if anyone (e.g. mail server) is asking any (other) DNS server "who's that guy?", that DNS will go to your provider's DNS and ask "so, it's one of yours, who is it?" and it'll be in position to either return some valid name (that's rarely free), delegate the task to some other DNS (mostly the case with IP ranges, bought by some organizations) or just shrug, which is often the case with common users. So the answer is likely - "it won't matter, you won't get a name", but that's entirely up to your ISP. That said, there are always possibilities to use the services of (or set up) some relay server or buy dedicated IP and tunnel traffic through it, but that's quite beyond the scope of question, I believe. Tunneling traffic, I'll keep that for other spare time in the year :) L

Re: [gentoo-user] mail server
Now I see more what ssmtp and msmtp are about so I have some questions. Is it possible to use an existing smtp port with them and be able to change the sender e-mail from my apache application ? Like it's transparently sending e-mail from my existing smtp account with my authentification but with someone else e-mail. For MTA: it involves installing a DNS server ? thx L Mike Kazantsev a écrit : On Sat, 24 Jan 2009 19:54:05 +0100 laurent wrote: I first just need my apache to send mails via mod_php and mod_neko.

Re: [gentoo-user] mail server
I will keep that in mind, the full MTA will wait a little a bit then. Thank you for the smtp servers ;) L Mike Kazantsev a écrit : On Sat, 24 Jan 2009 19:54:05 +0100 laurent wrote: I first just need my apache to send mails via mod_php and mod_neko.

Postfix -> LDAP -> AD That would be the setup I'd use. You'd need a how-to for exporting AD to LDAP and then one for Postfix accounts in LDAP. Both of those should exist in many different forms though it's possible that a complete AD/LDAP/Postfix how-to might exist.
