Impossible to send message to - MS Exchange 2010

[bbrock]

I'm getting the error below. We are on OTRS 3.1.3 and sending email through Exchange server 2010. I have set up IMAP, POP, and unrestricted forwarding via an alternate internal only IP address. I changed the domain name to protect the innocent.

Oops! An Error occurred.

Backend ERROR: OTRS-CGI-07 Perl: 5.14.2 OS: linux Time: Thu Aug 30 14:59:53 2012 Message: Impossible to send message to: bbrock@ourcompany.com .

I found several posts that put forward this error, but none of them seem to have a solution attached that works for our install.

We have the incoming email box working, it is creating tickets, in the correct queues, but none of the emails to the agents, or replies to the customers are being sent.

I've been trying to get this working for 3 days now, any help would be appreciated

Also, this was working in prior versions of OTRS 2.x, and stopped working when we upgraded.

plese check your Exchange logs

there were no logs that contained anything that was relevant. I noticed an error that RPC was not configured over HTTP, but the error didn't coincide with the email send errors.

I changed the relay to be completely open and it seems to work, but it's a large security issue that this is the only way to get it working. I would like to lock down the procedure to be SMTP relaying to my Exchange with a userid/password. Nothing that I've tried will work for that.

try it by telnet to port 25 from the otrs box. If it works, so will OTRS. http://support.microsoft.com/kb/153119

I did that before I posted here, and it works fine. It did not work for otrs

Can you provide a redacted screenshot of your Postmaster settings?

that's it...

That's receive. How about send? SysConfig, Edit Config Settings in Framework -> Core::Sendmail

[bbrock]

d'oh... sorry I knew better!

SendmailModule SMTP
SendmailModule::CMD /usr/sbin/sendmail -i -f -t
SendmailModule::Host mail.mycompany.com - I currently have this set to the internal IP that does unrestricted relay, but my MX host doesn't work
SendmailModule::Port 25
SendmailEncodingForce base64

the rest is left unchecked, but I had userid/password validation for the mx host for SendmailModule::AuthUser and SendmailModule::AuthPassword

I've also tried it with sendmail and every other combination I could come up with

[crythias]

You may need to put an email address in SendmailNotificationEnvelopeFrom

[bbrock]

thank you... that worked!
