Attachment Filtering Outbound

Attachment filtering based on filename patterns you specify, common text attachment file types and attachment MIME types can be applied to outbound mail just as it can be to inbound mail. See the BLOCK/ACCEPT > Attachment Filters page for details on settings.See also Content Analysis Inbound for details on attachment filtering features that also apply to outbound mail.

See Regular Expressions for text patterns you can use for advanced filtering. You can also specify one of the actions listed above to take with outbound messages if attached archive files (zip,tar, etc.) require a password to unpack.
