It is possible that the remote site (which appears to be 216.75.195.163) is complaining that your forward and reverse records do not match. I've seen some sites add this sort of check to their MTA and temporarily reject mail based on that. Assuming the mail exchange involved mail1.savola.com or mail2.savola.com, you may want to fix this anyway: $ host mail1.savola.com. mail1.savola.com has address 212.12.174.3 $ host mail2.savola.com. mail2.savola.com has address 212.100.209.92 $ host 212.12.174.3 Host 3.174.12.212.in-addr.arpa not found: 3(NXDOMAIN) $ host 212.100.209.92 Host 92.209.100.212.in-addr.arpa not found: 3(NXDOMAIN) .sf -- [email protected] mailing list
