How does the Personal E-mail Scanner work?

The Personal e-mail scanner is a plug-in which scans incoming/outgoing e-mails 
automatically. You can use it with E-mail clients that do not have their
own plug-in in AVG. So you can use it for example with Outlook Express, Eudora, 
Mozilla, Incredimail etc. If you have chosen the Personal e-mail scanner
to install during the AVG Free Edition installation, there are automatic servers 
created for e-mail control - one for checking incoming e-mails and the
second one for checking outgoing e-mails. Using these two servers, e-mails are 
automatically checked on ports 110 and 25 (standard ports for sending/receiving
e-mails).

Personal e-mail scanner works as an interface between e-mail client and e-mail 
servers on the Internet.

Incoming mail:

E-mail client sends request to Personal e-mail scanner to get mail, it receives 
message from the server and tests it for viruses, removes infected attachments
and adds certification. Then the message is passed to the e-mail client. The 
scanning of incoming emails is enabled by default.

Outgoing mail:

Message is sent from e-mail client to Personal e-mail scanner; it tests the 
message and its attachments for viruses and then sends the message to the SMTP
server. The scanning of outgoing emails is disabled by default.



Don't worry about what people think; they don't do it very often.
