I hope this thread doesn't exist already. I just followed the tutorial and some hours of googling later I am even able to login to squirrelmail and send mails. Unfortunately I cannot receive mails I created an account at dyndns.com (say: myacc.webhop.net) and pointed it to my machines IP address. This obviously does work since I can access squirrelmail via myacc.webhop.net/squirrelmail When I try to send a mail to firstname.lastname@example.org the mail does not show up in squirrelmail. Any suggestions? Many thanks in advance!
