Re: [SLE] Postfix pass-through server

Well, I have to argue with you... do you have any rpm package available for SuSE 8.0 / 8.1? I think not... Why bother to learn a very complex system in order to make a simple pass-through server?!??!

Well if you have never tried running a qmail MTA, I recommend it. See http://www.lifewithqmail.org/lwq.html for the URL that has everything you need. Excellent.

You need to allow relaying from whatever IP addresses your workstations (or other email/relay servers) will be using.

in /etc/postfix/main.cf, you'll find the "mynetworks" and "relayhost" config entries. mynetworks defines which networks are trusted to relay mail. relayhost defines a "smarthost" that Postfix will forward all mail to (if it isn't otherwise specified in /etc/postfix/transport table.

Of course, I prefer using Webmin (www.webmin.org) to do almost all my Postfix configuration.

Lines I add that I CAN'T use webmin for:

# TLS stuff (might not work with this version) smtp_use_tls = yes smtp_tls_note_starttls_offer = yes smtp_tls_key_file = /etc/ssl/private/devouredkey.pem smtp_tls_cert_file = /etc/ssl/certs/devouredcert.pem smtpd_tls_session_cache_database = sdbm:/etc/postfix/smtpd_scache

Also, if you ever have the host accepting main directly from the Internet, look into the following lines (also in main.cf):

maps_rbl_domains = dialups.relays.osirusoft.com, bl.spamcop.net, relays.ordb.org smtpd_client_restrictions = reject_maps_rbl

This can be configured through Webmin, and allows blacklisting of open relays (the source of 95% of Internet SPAM)

Give me an advice how can I set up the Postfix as pass-through on the dial-up firewall service for intranet SMTP server (Lotus Domino).

I going to set up the follow configuration. My system: SuSE 7.3 Firewall, dial-up fetchmail for fetching mail messages via POP3 to intranet mail server postfix for outgoing mail messages via SMTP from intranet mail server to provider

Don't hesitate to make me any advices, but Lotus Domino I can not to remove from LAN. ---- http://photo.alkar.net
