After some update a couple of weeks ago the Mail Shield has started to tag and quarantine an automated mail from one of my business partners as Virus, even thou it is not, and it was never tagged like this before the update.
It uses the - HTML:Url-inf [Susp] as the reason for this action.
The mail content is moved to Quarantine, but when I try to Restore it I only get the “Whoops, error occurred.” message.
The mail is clearly available in the quarantine vault, since I can restore it to a file and manually take it from html to eml and open it again in Thunderbird just fine.
I tried adding the senders domain to the Exceptions, but that had zero effect, since the mails are still tagged and quarantined.
So, WTF is happening with the Mail Shield on this new update?
