After SSL Installed on Exim, Can't Send to Remote Host

Hello Everyone, I've run into a curious situation with Exim and a signed certificate. I have a server (cpanel v11.52.0 build 18)that runs an issues tracker for my business, we'll call the host name vm1.domainname.com and the issues tracker domain name projects.domainname.com. I have a separate mail server that needs to receive the e-mail notices from the e-mail tracker. The domain name for the mail server is mail.domainname.com. In projects.domainname.com, I put in my mail server's SMTP information and wasn't able to connect due to a SSL error from the remote server. I thought this might be related to the system's SSL certificate so I decided to install a signed certificate. Because I don't want to spend tons of money on SSL certificates, I purchased a UCC multi-domain certificate. This multi-domain certificate includes domainname.com, mail.domainname.com, projects.domainname.com, and vm1.domainname.com. I logged into WHM, and went to Service Configuration->Manage Service SSL Certificates and installed this certificate there. Now when I try to setup projects.domainname.com to send to my mail server, the SMTP connection is rerouted to the local Exim server. It refuses to go to the remote server whether i use mail.domainname.com or the IP address instead just going to the local Exim server. If I use the IP address, I get the following message in exim_mainlog. If I use the domain name, I'm told that authentication failed (because it is checking on the local server). 2015-10-26 18:50:01 SMTP connection from [xx.xxx.xx.xxx]:44946 (TCP/IP connection count = 1) 2015-10-26 18:50:01 SMTP connection from vm6.domainname.com [xx.xxx.xx.xxx]:44946 lost (error: Connection reset by peer) 2015-10-26 18:51:07 SMTP connection from [127.0.0.1]:59936 (TCP/IP connection count = 1) 2015-10-26 18:51:07 SMTP connection from localhost [127.0.0.1]:59936 closed by QUIT I checked Tweak Settings->Mail and changed "Restrict outgoing SMTP to root, exim, and mailman (FKA SMTP Tweak) " to disabled. I also made sure that any DNS entries were set to use remote mailers. I'm not sure what to do next! Any ideas?

Hello :) Is this domain name added to the /etc/localdomains file or the /etc/remotedomains file? Thank you.

Thanks for getting back to me. Oddly enough, this just started working. I'm honestly not sure why it is, but it is. I don't know if an automated update fixed the SSL or what. The domain name was in /etc/remotedns like it is supposed to be. Anyway, it works now. Thanks for jumping in! Mitchell
