Scenario: Send SMTP mail Message Activity doesn’t complete or even doesn’t timeout

This is random behavior.
but the strange thing is - send SMTP mail message activity doesn’t throw an exception or doesn’t’ timeout.

it just gets stuck. and this happens randomly.

has anyone else noticed this behavior?
any suggestions?

Any errors in logs?


#3

No errors… it just gets stuck and then we have to kill manually…


#4

What smtp server are you using?


#5

we user Microsoft office365.com over standard port 587 with secure connection - StartTls
and also tried with auto.
Main problem here is that the activity doesn’t timeout or throwexception even after setting specified timeout duration, or even with default time out settings.
