Hi, My postfix mail servers shows to messages in the queue saying (host mx1.FreeBSD.org[69.147.83.52] said: 450 4.7.1 Client host rejected: cannot find your hostname, [86.58.167.132] (in reply to RCPT TO command)) But when i do a lookup or a reverse lookup, i find my hostname. Does mx1.freebsd.org have an old dns? / Ebbe
