Email issue as of early this morning. multiple servers

I am using the “Automatic” selection under Advanced email settings.
It had been working for several months.

I am getting an email error on the backup confirmation on multiple servers as of early this morning.

the error is: Can’t send email to system.monitoring@XXXXXXXX.com: Could not load file or assembly ‘HtmlAgilityPack, Version=1.4.9.5, Culture=neutral, PublicKeyToken=bd319b19eaf3b43a’ or one of its dependencies. The system cannot find the file specified.

Nothing has been changed on those servers. All are licensed professional edition.

Any suggestions?

I have switched to an email we are providing, rather than the automatic option, and it is now delivering successfully.

I am not deleting the thread though, as you might find it helpful in the event it is occurring with other people.

I had the same problem on multiple installations and today seems that it works.
I looks like a central SQLBackupAndFTP problem on this service…

Hi,

Yes, that was a temporary issue on our side and we have fixed it.

Sorry for the inconvenience.
