njabl.org shut down
Hi for info http://www.njabl.org/ March 1, 2013: NJABL is in the process of being shut down. The DNSBL zones have been emptied. After the Internet has had some time to remove NJABL from server configs, the NS's will be pointed off into unallocated space (192.0.2.0/24 TEST-NET-1) to hopefully make the shutdown obvious to those who were slower to notice. its also included in policyd-weight Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Joerg Heidrich
Relay Host Based on From address
I am running some mailman mailing lists and due to issues with my ISP's SMTP server I need to use alternate mail relays. I need to configure postfix to use a relay, with authentication, based on the local originating address rather than the destination. Is this possible and can someone point me in the right direction? Thanks. signature.asc Description: OpenPGP digital signature

Thanks. the From-header is not relevant for SMTP becasue headers have nothing to do with the SMTP MAIL FROM command http://en.wikipedia.org/wiki/Bounce_address ___ however, besides these basics a mailadmin should know http://www.postfix.org/postconf.5.html#sender_dependent_relayhost_maps see example below please totice that i use here the submission port 587 because if we speak about authentication we are acting more than a MUA and submission a) requires auth and b) has usually different restrictions because auth is given notice also that how you write realyhost/port has to be 100% identical in sasl_passwd and relayhost_maps and you can list as much user/password/host-combinations as needed ___ /etc/postfix/main,cf: smtp_sasl_auth_enable= yes smtp_sender_dependent_authentication = yes smtp_sasl_security_options = noanonymous smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd sender_dependent_relayhost_maps = hash:/etc/postfix/relayhost_maps /etc/postfix/sasl_passwd: # AFTER CHANGES: postmap /etc/postfix/sasl_passwd [relayhost]:587 username:password /etc/postfix/relayhost_maps: # AFTER CHANGES: postmap /etc/postfix/relayhost_maps sen...@domain.tld [relayhost]:587 signature.asc Description: OpenPGP digital signature

Re: Relay Host Based on From address
Exactly what I was looking for. I never would have thought used 'sasl sender' in a search engine. Thanks.

question re. sasl authentication
Hi Folks, I just had a users' password compromised - with the result that a bunch of spam was sent through her account. (Fixed by changing her password.) But, in the process, I had to learn a lot about how Postfix wires together with Cyrus SASL, and that in turn with PAM. I discovered something that confuses me, and I hope someone can help: - our system is set up to authenticate smtpd transactions via saslauthd (and then to pam_unix to the password db) - as soon as I changed the user's password, IMAP started failing authentication and the password had to be changed, BUT... - we could still SEND mail via smtpd using either username/newpassword or username/oldpassword - eventually this timed out and the old password stopped working - obviously the old password was being cached somewhere, my assumption being in the saslauthd credentials cache, BUT, that doesn't explain why smtpd continued to accept the old password for a while Which leads to several questions: - the general one: anybody know what's going on? - is postfix doing some of its own authentication caching (as suggested by the variable smtp_sasl_auth_cache_time) - and most important: is there a way to flush the cache?
