Please be aware that a rapid transmission of viruses through misleading emails from user to user in ongoing for the last couple of days. Viruses are contained in infected Microsoft Word documents that are attached to the deceptive emails. The deceptive emails are constantly mutating and they do not have a unique feature that would allow them to be excluded from antivirus systems.

Because of this, since Wednesday 14/10/2020 at 21:30, the messages that carry an attached document in Microsoft Word format are excluded and will be dropped by the AUTh mail servers.
