osTicket not respecting SMTP settings

madonid

Under Emails -> [email address] -> Outgoing SMTP, I have filled in all the necessary server information and checked the Enabled radio button. When I go to test the setup using the Diagnostic screen and the selected email address, the email fails with a log message of "Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()"

That indicates to me that it's trying to use my PHP SMTP settings and not the settings I put into the SMTP tab for the email address. How can I get the email test tool to use the settings I configured in osTicket and not the PHP settings?

When you set to enabled you have to save changes.

Thanks. I tried that, but just to be sure, I Disabled, then saved, then Enabled, then saved. Still having the same issue.

So it saves successfully whilst enabled? Then that means the connection is succeeding. You need to check your system logs to find relevant Mailer Errors. PHPMail/Sendmail is used when SMTP fails or is not configured.

Issue resolved, thanks Kevin. More info below in case anyone else runs into this issue.

The key troubleshooting tip was that osTicket falls back on PHPMail/Sendmail after a failed SMTP attempt. The answer was in the log, but every time I would test SMTP and fail, I kept looking at the latest log entry, which had the PHP mail error. I needed to look for the error immediately before it showing the first SMTP attempt that failed:

Once I realized that, the error message (and some Googling) indicated that I had one more step to do with the MailerSend SMTP service I was using before the account would work. I completed that step on the MailerSend end, and now I can send emails from osTicket.
