error messages and test e-mail are received ok.
Until recently the mail with a snapshot of the security cam where received.

the snapshot works in the camera settings menu

Does this smtp server you use, support multi form html emails?

I seems it Doesn't.
Other server, no problem.
It is a Synology mailplus server, so I am a bit surprised.
But it definitly not a Domoticz problem.
Tnx for the assistance.
