I am running osTicket v1.8.1, Apache, PHP 5.5.27, MySQL 5.5.42, Web host is on CentOs (Hostgator), email is on external mail server, which is firewalled by mxlogic. IMAP settings function correctly and the system now fetches email using CRON. However, my SMTP settings receive the below error:
Failed to connect to webmail.domain.com
I attempted to troubleshoot this issue with my email host for over 2 hours, allowing traffic to ports 25, 465, and 587, which did not yield any results. I have not disabled SeLinux (don't know how to do this - cannot find it in my File Manager). Does any1 have ideas?
