Hi there,
this a new Bug. Mail manager shows malware (antivirus engine error) for a normal newsletter mail.
In daily Quarantine Report this mail is shown with reason "SPAM". If I release this mail over the embedded link. The mail comes for one account destroyed into the mail store and the utm generates a mail with the hint that the mail was rescanned and a virus has found. For the second account I can't release the mail. If I release the mail from mail manager, all is working as expected.
Regads,
mod
