CMS Made Simple Forums

For some reason the CMSMailer can no longer allow mail to be sent via SMTP.

I have checked the settings on the CMS and they are correct.
I have also checked using a SMTPer service external from the CMS and it works as expected.
I have tried using mail() and sendmail() and neither work direct from the server.
I have tried multiple port, TLS and SSL settings and nothing is getting through
I have tried sending to multiple addresses on Exchange and POP3, but nothing gets through.

I do get an SMTP connect() fail message popup in the CMS stating to see the PHPMailer troubleshooter, but no other information.

It was working fine until 10th Jan 2020 as this was the last known email received via the service?

I use sendgrid to smtp relay, however I have also tried mailgun and the same thing happens.

This occurs on CMSMS 2.2.3.1 and CMSMS 1.12.2

many thanks

Sounds like your host has changed something. I know some hosts are adding methods to limit email relays, and you have to register the sender address in their control panel.

It's also possible they changed php versions and your old CMSMS versions aren't compatible with it anymore, although that sounds less likely (you still should upgrade though).

It turns out that the issue is with the hosing provider and a server update that has killed something on the server, not ver forthcoming with what was broken and why, but at least it is not CMSMS that is causing the issue.
