Abstract: A method of detecting malicious electronic messages transmitted from at least one message sending device to at least one message receiving device includes: generating at least one signature for an electronic message; storing the generated signature in a data storage unit; determining whether the electronic message is malicious; if the electronic message is determined to be malicious, determining on the basis of the generated signature, whether electronic messages comparable to the determined malicious message were classified as non-malicious and transmitted to the message receiving device in the past; and if it is determined that electronic messages comparable to the determined malicious message were classified as non-malicious and transmitted to the message receiving device in the past, notifying the message receiving device about a potential threat. Also disclosed are a messaging server and a messaging system implementing the above described method.

Abstract: The disclosure relates to a method of detecting suspicious electronic messages.

Abstract: The disclosure relates to a method of transmitting fax messages from at least one fax message sending device to at least one fax message receiving device. The method is implemented in a fax communication device driver. The method comprises the steps of receiving, from a fax server software module, fax data associated with a fax message to be transmitted from a fax message sending device to a fax message receiving device; deciding, on the basis of at least one predetermined routing rule, whether to route the fax data to the fax communication device or to the cloud provider; and based on a decision result, selectively transmitting the fax data to the fax communication device or to the cloud provider for transmission to the fax message receiving device.
