Hello Oliver,
I am pretty sure that credentials will be working correctly. I have typed and pasted the credentials for several times. Nevertheless the SMTP Mailer Plug-in should be a reference to yours. I have tested both and came to the point that both will have similar behavior while using the correct credentials. The SASL Auth will not be performed correctly. This is a bug regarding PHP and can be fixed simply disabling the cert validation. (My perspective) can you please provide PHP version of the testing environment? How can I disable cert validation within your phpmail class?
Regards
Carsten
