Test Email fails but sends several mails (not RFC 2822 compliant)

Hi,

Thank you for great Xibo!

For alerts I tried to configure email. "Test email" sends email, but complains that test fails. Also it sends several mails so that I have >20 test mails on my mailbox. I found similar question #223562, but there were no solution. I also tested several destination addresses. For google I managed to trap error message from delivery system (our ISP):

I found some descriptions for the error message (not RFC 2822 compliant). All email addresses are valid, so this is not the case. In some solution they changed \r\n at end of line to \r only, so it worked. This was also case in missing fields.

Thanks
