So I have been racking my brain and searching these forums for an answer to what appears to be a fairly common issue. None of the threads I have seen seem to have a resolution.
So everything seems to work fine execpt for incoming mail. When I do a test of my settings I get a certificate error

Test Settings

Certificate failure for ex01.myserver.com: unable to get local issuer certificate: /C=US/ST=NJ/L=Mytown/O=domain Inc./OU=domain.com/CN=ex01.myserver.com

Please check your settings and try again.

I believe this is also affecting my ability to send outbound, since I cannot seem to get mail to send from campaigns either. Can someone please help!

I am using a freshly downloaded Sugar Pro version 4.5.1 it is installed on Ubuntu Dapper 6.04

Any diagnostics I can try? Does anyone else have this issue?

I have tried it all I have deleted the account and recreated as was suggested in 1 thread, I have verified all of my php.ini settings, that seems to be ok.
