Confused about SPAM Detection

[leebe]

Hi,

I am busy setting up the SPAM Detection and noticed this:

SPAM Filtering Settings
This service allows you to enable various SMTP level filters which will help reduce or even prevent unwanted SPAM mails. Please note, these options do not affect mails received by WebMail or POP3 Retrievals, they are only applied to incoming SMTP connections.

so.. does that mean incoming mail does not get filtered? only sent mail?

No, all incoming and outgoing mail is filtered as long as it comes through SMTP (i.e. from a mail client or other mail server). Mail created via WebMail will not be filtered but POP3 retrieval mails are now scanned by SPAM filtering for black listing, white listing and Bayesian filtering.
