This line alone is not really correct: 450 4.7.1 Client host rejected: cannot find your hostname, [212.69.162.205] But as Wietse said, there's another log line explaining the problem: warning: 212.69.162.205: address not listed for hostname protegate5.zmi.at I just looked at the one line in the mail report, and that alone is not correct, as there is a hostname PTR for that IP. > This kind of "misfit" is commonly referred to as a "DNS issue" when > postmasters talk to each other ;-) Yes, once you know it it's easy to solve anyway. mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0660 / 415 65 31 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: AC19 F9D5 36ED CD8A EF38 500E CE14 91F7 1C12 09B4 // Keyserver: wwwkeys.eu.pgp.net Key-ID: 1C1209B4
