Spam - Auto-Whitelist / Learn from outgoing mails

[m1byo]

A useful feature for the anti-spam would be to allow the Spam whitelist to learn from outgoing emails (as outlook does) so that any emails which have been replied to or are from that person at a later date are not blocked.

Also, along the same lines but probably a little more complicated, It would be again useful to have the baysean spam filter to learn from the outgoing mails of users. This would then force the spam filters to almost immediately include the sort of emails which the users have replied to along with the general content being discussed by the users.

Thanks very much, it is a brilliant product so far.

We are considering several possibilities for extra ways of training Bayesian. A recent forum suggestion was to use the SPAM White List for training of non-SPAM mails. There is also an option next to that to skip SPAM filtering if allowed relaying access. Again, being allowed relaying access (outgoing mails) could also be used as a trigger to learn from non-SPAM mails. Note that you can set the user Account Options to save outgoing mails in a folder and you can also set this folder as a non-SPAM folder for Bayesian Auto-Learn From Users training which would effectively train from all outgoing mails. We are also planning on improving content filtering to include a Bayesian training condition so that you can train based on any number of criteria. All of these things are planned for future updates to come.

I have setup some content filtering scripts that run a few batch files in the background to ask senders, whose email is recognized as potential spam, to reply back and be auto-added to the whitelist. Then, so that their messages don't continue to get flagged and routed by the spam-related content filters, when the person emails again, another filter sees that the sender is already in the whitelist and pushes them past the content filters that would normally drop them into a Junk folder. I also setup a rule that allows a user to send an email to a spambot mailbox on the server, and if it has a special phrase in the message subject, it will add any email address that were put in the CC field into the whitelist. That way, a user can add whomever they wish to the whitelist without making them get processed through the auto-whitelist rules in the content filter.

Basically, it is an automated whitelist workaround since the mail server does not currently offer one.

We are planning to add a proper challenge response SPAM filter in a future update to do this properly.
