Don't Delete Spam Automatically

Filtering spam is a tricky matter. While many clever strategies exist that can significantly cut down on the amount of unsolicited mail in your Inbox, no filter can be 100% accurate.

There will be spam that slips through the filter or — worse — legitimate mail that's caught by the anti-spam filter.

That's why it's a good idea to

• build a safety net into your filters.

Do not delete mail immediately with an anti-spam filter, do not even put it in the trash.

It's usually better to have a special "Possibly Spam" folder where filters put the suspected spam. Every few days you can have a look at the contents of this folder and, if it does not contain any legit email, empty it.
