Error: 602 - Certificate is expired
Problem reported by Martin Schaible - 2/10/2024 at 2:42 PM

This week this issue with the error 602 escalated a bit. We had every day a few mail stuck in the queue.

The problem is this: The sending E-Mail account get's no feedback from the SmarterMail server, that the mail is still in the queue and it will never be sent. 

This caused problems for the customers, because his thought, that the mail was sent. 
The last thing i need is to get troubles with the customers. They don't care, that a certificate of the target server has expired.

I had to tick "Bypass certificate validation check". I had no other choice.

Not so fun fact: I contacted some administrators (postmaster@...) via my GMail-Account to inform them, that their certificate is expired.
- None of them answered
- Even after a week, they didn't renew the certificate. Lazy stupid people, really.
- Google ignores expired certificates.

Google dont care about security... Google is one of the biggest spammers in the world.

And you should care and dont compromise on email security. INform your customers and make sure they are aware that their clients or vendors dont give a shit about security.

We encountered the same, and applied the same. 

In the past, I remembered SmarterMail will retry to deliver it in plain-text connection around 1 - 2 minutes later if destination mail server SSL expired.  
I do not know why it does not retry it in plain-text afterwards, simply keep in the queue.
