Right chaps a tricky sticky one me thinks can anyone help?
I'w working on a customers site then runs Exchange 2003, the MD has a MAC at home that wants his Business email setup on it.
He brought it into the office and I set it up no problem tested all ok on the internal network incoming on IMAP and outgoing to SMTP also tested it on a wireless 3G dongle so it worked external too.
He took it home and reports he can recieve email ok but not send it.....?
so i go to his house to check, all settings are perfect and it just sits there, I diagnose further by RDP to the exchange server and checking it's connections to the SMTP server and when the MAC tries to connect it comes up with the connection in exchange SMTP as a connection it even has the username of the MD so i know it the MAC that's connected in so that rules out firewalls etc as it does connect you see but one thing i have noticed is the public IP thats displayed in the SMTP server is different from the public IP address of the MAC's internet connection i found this IP to belong to BT some sort of relay or somthing and yes the MD's ISP is BT, I even trusted this IP address in exchange to all relay but still will not send.
on the MAC using connection doctor I find in it's logs it does connect and send the EHLO or HELLO commands yet email wil still not relay.
So its somthing to do with the BT network can anyone
Help..... im going nuts here
BTW it works fine on all iPhone on the 3G connection and all other users home broadband wireless etc not tried iPhone on the MD's home broadband though
