This page contains configuration options for the spamassassin mail filter and how it should manage the e-mails recognised as spam.
On this page, by ticking the appropriate checkboxes, a few global configuration settings of the POP3 proxy can be enabled.
When the checkbox is ticked, also connections over SSL/TLS are scanned for virus.
New in version 3.0.
This page allows to configure how the POP3 proxy should proceed when it finds a spam e-mail.
Even when an email has been marked as spam, it will be delivered to the original recipient. Indeed, not delivering it would break RFC 2821, which states that once an email is accepted, it must be delivered to the recipient.
To detect spam e-mails using pyzor (in short: spam e-mails are converted to a unique digest message that can be used to identify further analogous spam e-mails).
Activating this option might considerably slow down the POP3 proxy!
The settings can be saved by clicking on the Save Button.
The Endian UTM Appliance is unable to scan the e-mails sent through a POP3 SSL connection since it is an encrypted channel.
Therefore, to allow a client to use POP3 over SSL it is necessary to appropriately configuring it and to disable the encryption from the client to the Endian UTM Appliance. Encryption should be disabled (i.e., do not use SSL), but the port for POP3 traffic in plain text changed from the default 110 to 995.
After setting this configuration, the connection from the client to the Endian UTM Appliance will remain in plain text, but it will use port 995, making the Endian UTM Appliance setup an encrypted POP3 over SSL connection from it to the POP3 server.
