I am having a very serious and irritating problem.
a client of mine is not receiving email into his exchange mailbox from (as far as we can tell) random contacts.
I have managed to find a specific e-mail that is not being delivered to his mailbox and can replicate this by resending the message to the Pop3 account from our offsite spam firewall.
What I have tried.
1.) i resend the mail to the pop3 mailbox.
2.) i can view this via the ISP webmail interface.
3.) i attempt to download the mail using the pop3 connector in SBS 2008 .
4.) I check the message tracking and the mail has not been received by the smtp "interface"
I attempted to install another pop3 connector www.mapilab.com/exchange/exchange_pop3/
which did the exact same thing.
What next? where can i access the logs for the smtp service?
PLEASE HELP!! :)
