I am very new here and start playing with selfhosted OsTicket today. During email setup, I am having problem in "Sending Email via SMTP". Below is my setup:Hostname: rhw9009.star1.nesdis.noaa.govPort number: 587But I get the message "Failed to connect to rhs9009.star1.nesdis.noaa.gov ".I also tried port 25, and got the same error message.FYI, I have another ticketing tool installed on the same machine, and I have verified the above SMTP server and port 25 work successfully on that tool.Any help is apprieciated.Below is the OsTicket that I installed:osTicket Version v1.9.2 (4827655)Server Software Apache/2.2.15 (CentOS)PHP Version 5.3.3MySQL Version 5.1.73PHP Extensions gdlib Used for image manipulation and PDF printing imap Used for email fetching xml XML API xml-dom Used for HTML email processing json Improves performance creating and processing JSON gettext Improves performance for non US-English configurations mbstring Highly recommended for non western european language content phar Highly recommended for plugins and language packsPHP Settings cgi.fix_pathinfo = "1" is recommended if AJAX is not workingDatabase UsageDatabase Space Used 0.26 MiBDatabase Space for Attachments 0.01 MiBThank you in advance,Jewel
