I asked a very similar question some 4 or 5 months ago, but haven't tracked down a suitable answer. I decided to post a new question so that I can ...
a) Post updated info
b) post my most current postconf -n output
When a user sends mail from inside the network (via webmail) to email addresses both inside and outside the network, the email is delivered. When a user with an email account on the system sends mail from outside the network, using the server as the relay, to addresses inside the network, the email is delivered.
But [sometimes] when a user connects via SMTPD to send email to an external address, a Relay Access Denied error is returned:
Feb 25 19:33:49 myers postfix/smtpd[8044]: NOQUEUE: reject: RCPT from host-68-169-158-182.WISOLT2.epbfi.com[68.169.158.182]: 554 5.7.1 <host-68-169-158-182.WISOLT2.epbfi.com[68.169.158.182]>: Client host rejected: Access denied; from=<

Sending this through Microsoft Outlook 2003 generates the above log. However, sending through my
iPhone, with the exact same settings, goes through fine:

Outgoing Settings on Outlook 2003 match the settings on my iPhone:
SMTP server: mail.my-domain.com
Username: My full email address
Uses SSL
Server Port 587
Now, here's postconf -n. I realize the "My Networks" Parameter is a bit nasty. I have these IP addresses in here for just this reason, as others have been complaining of this problem too:

If anyone has any ideas and can help me finally solve this issue once and for all, I'd be eternally grateful.
