How does SpamDrain work?
Well that depends a bit on how it is set up.
CLEANS
With a basic SpamDrain setup every e-mail first lands in your online e-mail account and SpamDrain continuously monitors* your e-mail account and clean it from spam and viruses.
FILTERS
If you have a SpamDrain+ account the spam can either be cleaned out as above or it can be setup so that all your e-mails pass through our servers where spam and viruses are filtered out and the real e-mails are then delivered to you.
*Accounts set up with IMAP-fetching are constantly monitored, spam is cleaned out only a few seconds after arrival. With POP3-fetching accounts are checked and cleaned every 30 seconds. Spamdrain always tries to set it up with IMAP as this is better . If you are using PO3 the cleaning of our inbox might not work as smooth try to change to IMAP if this is possible.
