Hi,
| I seem to have a problem, whereby my mail server is try to
| send an email to epost1.koping.net.
|
| I tried a telnet session and I get this below:
|
| mail:/etc/exim4# telnet epost1.koping.net 25
| Trying 81.16.160.67...
| Connected to webmail.koping.net.
| Escape character is '^]'.
| 553 Your computer does not have a hostname, access blocked
seems like you don't have a valid reverse lookup ?
