Hi,
Does anyone know the reason why sending an email from OTRS 5.14 takes about 5-10 seconds when using TLS (587) encryption. And when using SSL (465), mailing is done immediately?
I'm talking specifically about Office 365 servers smtp.office365.com. They do not offering SSL option, only TLS.
Thanks.
Regards,
Sasha
