XF 2.3 email error stream_socket_enable_crypto(): SSL operation failed with code 1.

[Mr Lucky]

This morning from about 1:am to 10:23 am I have a load of email errors. When I check my postmark activity statistics I can see no emails were processed during this time period. Then I see they all seem to start again, with quite a few all sent at 11:52.

SMTP provider is postmark and no setttings in either postmark or the forum admin have changed re: email settings for years. Upgraded to php 8.3 a couple of weeks ago.

Can anyone tell from the error what this might mean?

Thanks

Thanks Matt. Not a good reflection on Postmark IMO
