I have a broad question that I need some help with. I handle the IT responsibilities for a small company and want to move some users from Blackberry to iPhone and Andriods that they have. Instead of carrying 2 phones they want to drop the blackberry.
Sonicwall Firewall TZ200W
Barracuda Anti-Spam Firewall
Microsoft Small Business Server 2003
So far I can connect to OWA (Outlook Web Access), and IMAP to get mail, but I cannot send via the IMAP configuration. I cannot get SMTP to resolve to send email. In the iPhone I can also get mail via IMAP but not send via SMTP.
The built in exchange connection that the iPhone supports does not work either.
I know we do not have a mail.domain.com DNS record, so is that part of the problem?
So I'm trying to setup exchange on the backside, the firewall in the middle and DNS on the net. I know the firewall is allowing IMAP to get email because I get the messages on the iPhone and I can get the IMAP messages on a laptop running Outlook.
