I'm afraid I couldn't tell you how to make Exchange listen on two ports at the same time but it looks like someone else has got the answer.

You can change the services file just like in unix, have a look here: http://support.microsoft.com/default.aspx?scid=kb;en-us;173903 The article is based on Exchange 5.5 (I wonder when they'll start calling it Exchange Classic) because there is no way to change it from the Exchange admin software in that version. I think they changed this behaviour in later versions but if you can't find the setting then it's probably worth giving it a bash.

I definitely think this is the correct way to solve this problem, but if it is possible do you know how (or any links to some info). I was under the understanding it wasn't possible to change it (but they are Windows admins and not used to the freedom of choice). BTW, it seems to be Exchange 6.5.

Postfix supports the Standard way (Client-Side) where the Connection is established unencrypted and the Encryption is switched on after that (STARTTLS). Most Clients will support the SSL-Mode, so you will have luck with Clients. > My ISP blocks all port 25 traffic to force > all smtp traffic to go through them.

TIA for any help or alternate ideas. Hmm, the best way would be to configure your Exchange Box to listen on a second Port with TLS enabled maybe 465 or 26 or whatever. Another way of course would be to setup stunnel on your Home-Postfix-Box to reconvert the encrypted Session in an unencrypted. -- Andreas -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
