I don't see any errors in /var/log/mail.log
I sent mail from my ISPs email to my newly created domain email and then logged into the webmail client and refreshed the inbox a few times. This is what the logs say.
Email addresses have been edited.
my_email@home_domain.net This is my home email address.
web2_ispconfigmail@localhost.com This is the mail login created by ispconfig
admin@local_domain.com This is the mail address the original mail was sent to. It was setup through the options in ISPconfig also.
Here's the log, I can repaste it here if you don't allow linking to pastebin.
