hi,
I need urgent help with smtp that is being blocked by the firewall..... i think?!

i've setup a domain ex. mydomain.com but an ISP hosts our e-mail. We have 2 braches, so not all the users from my domains e-mail come to my server. What I did was to ask the ISP to forward specific users to an external e-mail account and then use multi-drop to put it back in the correct mailboxes. This works fine except when the users wants to send mail to users on the same domain (not @ our branch but to our second branch) I went to the e-mail clients (outlook & outlook express) and set them up to send mail directly to the ISP’s SMTP. But my server still seems to intercept it (forcing it to do a local delivery) thus giving me an error saying the user does not exist.
Am I right in assuming this is because of masquerading on my firewall on port 25.
How do I fix this ?

PLEASE HELP !!!

i think it's because outlook or outlook express is sending it to the SME server, i have a server at my work, and it doesn't intercept mail if we send it directly to the ISP's SMTP server, check your outlook settings, I'd say that's where your problem is.

hope that helps
cheers

This is an FQA. The Search function is your friend and so are the release notes:

---------------------------------------------------
A transparent SMTP proxy has been added, to force all outgoing SMTP connections to go through the SME server. This feature enhances security with respect to viruses and worms that use SMTP to propagate themselves.

If you wish to disable this proxy, you can do so via:

/sbin/e-smith/config setprop smtpfront-qmail Proxy disabled
/sbin/e-smith/signal-event remoteaccess-update
