I recently had to change from a Real IP range to a 192.168.100.x range. Ever since this change I have not been able to send email outside of my network.
I get "one of the recipents was rejected by the server. server response 552. Relaying denied for rcpt blah@blah.com"
Everything used to work fine.
I am now using fetchmail to get my mail. but can't send.
any ideas ?
