The setup is as such, that cruwe.de is a FreeBSD box and mail.cruwe.de is a jail on cruwe.de, to which the mail ports are forwarded by packet filter. Both cruwe.de and mail.cruwe.de are addressed with A records. The mailer answers "220 mail.cruwe.de ESMTP Postfix" when telnet'ed, so I guess that is what the mailer returns as hostname. I did not know about that DNS/rDNS issue ... $ dig mail.cruwe.de ; <<>> DiG 9.4.3-P4 <<>> mail.cruwe.de ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2343 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;mail.cruwe.de.

Am I right that I need to set the rDNS of 188.40.164.98 to mail.cruwe.de to make the freebsd.org servers accept my mail or that, should I set the rDNS to cruwe.de, I should make the mailer on mail.cruwe.de identify itself as cruwe.de instead of mail.cruwe.de? Anyway, thank you very much for your help, -- Christopher J. Ruwe TZ GMT + 2
