popping from exchange 2007

  • 772

I'm having issues getting a linux box to pop from exhcange 2007.

This all started while setting up osticket. Once I had everything configured I get an invalid username/password them attempting to test the account settings.

I installed pop3test on ubuntu and found that the only way I can use it to get a clean login test is with the following command.

pop3test -a username -i mailservername which outputs this:

  1. In your pop3test command, you are using NTLM authentication; your Fetchmail log suggests it is doing PLAIN. If your server is only set up to respond to NTLM correctly, you may need to ensure that NTLM is compiled into your Fetchmail binary and enable it in the fetchmailrc file.

  2. For one reason or another this actually was a credentials issue. I had an account named Maintenance with username/alias maintenance and email address [email protected]. I created a new user account calle maint, with username/alias maint and email of [email protected]

    for some reason maint works in all cases where the maintenance account does not, I've still not tracked down the exact issue but it is up and running...

    I've found a permanent fix for this issue here: LINK

    It lets you disable TLS in the PHP mail client that osticket uses.
