Since updating 9.1 outbound mail functionality broke for me.
Found in a another topic mail component was changed to symfony.
Had a bit of a time getting that to work with my (local) SMTP gateway so figured I'd supply some freedback.
First, the option of turning off encryption does not seem to work, even with it set to the empty (none) value I can see in the logs it keeps trying STARTTLS.
Ignoring that, it trips over the the fact the server has a self signed certificate:
And after I fed my mail gateway a trusted certificate it took issue with using an IP instead of a hostname.
Which I could also address with an internal resolve to the the same ip using the name in the cert and changing this in Espo.
This new situation seems very geared toward using some kind of external service?
I think turning off encryption should work, and I feel there needs to be an option to disable verifying the certificate.
AFAIK self signed certs on SMTP servers are still fairly common as mailservers don't really validate certificates.
