SMTP - Dropped due to TLS engine error: FLOW_TIMEOUT[5] - can't send emails from printers using tls

Hi,

the answer is to put an exception and that then defeats the purpose of scanning. Does the printer have a CA installed?

Try using the XG mail proxy with smtp/s scanning enabled.

We use office365, no XG mail. Until now it was not necessary to use a certificate. Which exception do you mean?

Hi Philipp Marx,

Thank you for reaching out to the Community! 

If you did not configure email protection on the XG firewall, please disable the SMTP/SMTP scanning rule. This rule is auto created for email protection in MTA mode.

Thanks,

Thanks for your feedback. I have disabled the SMTP scanning. The error still occurs. 

If I change the settings from 587 TLS to our relay port 25 the scan to email works. 

I figured out that this happens with HPOfficejetPro8730 8720 Serie only.

I tested the settings with an HPOJPro9020 , the same TLS settings port 587 and scan to email works without the log entry "Dropped due to TLS engine error: FLOW_TIMEOUT[5]".
