Zimbra Webmail Spam / Junk Mail Frequently Asked Questions
Most filtering of unsolicited automated email (also known as spam or junk mail) is handled by a spam filter before those email messages reach their Inbox.
Email that might possibly be junk mail, but is not certain to be junk, is placed in their Junk folder. You can review these messages and either move them out of the Junk folder or delete them. If you do not move or delete the messages, they are purged after 30 days.
If you have an incorrect message marked as spam, check for the following:
- Messages you have bcc'd yourself in may go to spam.
- Spammy subjects such as blank subjects or short 1-2 word subject lines
- Emails with no content
- Emails with only a url as content
Some unwanted messages may not be fully categorized as spam and are not placed in the Spam folder (ie. weekly newsletters and advertisements from legitimate companies). The best way to handle unwanted mail from legitimate senders is to unsubscribe from the mailing list.
