Hi Due to a HD crash had to reinstall Dapper and ISP Config. Had a problem with gcc4.1.2 and reverted to gcc 3.4 plus modded file as per: http://www.howtoforge.com/forums/showthread.php?t=19222 Thanks very much. But whilst everything seems to be working no emails are arriving 'outside' internal emails are working fine. Incoming emails/spam also fine. To help:- I had to set up server at another location and re set /etc/network/interfaces and /etc/hosts to current host. Secondly the Outlook 'test' message does not work and thirdly I cannot ssh in from other than the same network. I suspect DNS settings - it works on local (192.168.1.250) but not on mailserver.martley.org. Any help would be appreciated from this 'newbie'
