After installing (from scratch, apart from /home directory) FC2, I can no longer receive mails from a particular address. I used to receive mails from him when I had FC1 installed. The address concerned has an MX record - I can get a listing with dig -t MX, but if I omit the -t MX record, then I get: Truncated, retrying in TCP mode. and then timed out - not servers could be found. fetchmail/sendmail rejects his emails with: maillog.1:Jun 7 23:53:45 colina sendmail[29693]: i57MiHN5029693: ruleset=check_mail, arg1=<neal@xxxxxxxxxxxx>, relay=localhost.localdomain [127.0.0.1], reject=451 4.1.8 Domain of sender address neal@xxxxxxxxxxxx does not resolve So my questions are: 1) Is there a fix for this? and if not, 2) Can I tell sendmail to always allow this particular address through? -- Colin Paul Adams Preston Lancashire
