Three things you should do : 1. using a sniffer (look for Ethereal) check for what is sent through the smtp protocol to the Exchange server using Outlook Express. That way, you'll be able to see if there're special headers that are sent. 2. Check for the Phoenix source code and see if there's any "workaround" when connecting to Microsoft application 3. Do the same as in 1. but using Phoenix. And then compare the differences (or not) between 1. and 3. and then do the same with your own application. > The mail server is on a customer site, so we don't have direct access > to it. No need.

Another thing to do is to use the telnet application and simulate a SMTP connection and see what's going on...

Re: [twsocket] [tsyncsmtpcli] Problem sending email to Exchange2000server
Just a recap on this one: more info now. We have an ICS-based email app that is having difficulty sending messages to Exchange 2000 server. Specifically, we can send internal emails but not emails that would need to be sent over the internet. No error is reported by ICS, the email just disappears. Outlook Express works and can send external emails. *Also, Phoenix (which is an open source application and nothing to do with OE) can also send external emails*. So this seems to be a problem with ICS. One thing which may/may no be significant: our app just sends emails using SMTP. It doesn't read them via POP3 like Phoenix. The mail server is on a customer site, so we don't have direct access to it. We are at a loss at the moment. Does anyone have any idea what could be causing this?

Our client is not using SMTP authentication, but neither is OE. I'm going to give SocketSpy a try to see what could be up. Thanks to everyone for their help.

We get customers emailing us all the time saying "Outlook works fine, but your [SMTP based program] won't send emails outside of our domain!" It's always that Outlook is connecting to the server using IMAP and the settings on the server are set to allow those emails to "relay" or whatever. I would double- and triple-check the settings on Exchange to make sure that emails coming in over SMTP can send out to the internet. Exchange is a beast with way to many stupid settings. The only other thing I can think of still has to do with the server side: see if there's some settings in Exchange that limit who can relay emails based on what type of authentication they use to access the server. Maybe Outlook is using one type of authentication while your SMTP client is using a less secure method (or no authentication at all).
