MAIL ATTACHMENT FILTER CONFIGURATION
The Mail Attachment Filter module allows filtering of mail attachment whether it is a MIME or non-MIME message. This module supports filtering of mail attachment given the content-type, a filename only, or both content-type and filename. It also supports usage of "*" wildcard to both the content-type and filename fields. This page allows you to add or delete a mail attachment filter.
To add a new attachment filter, do the following:
- Indicate the Content-type and/or the Filename of the message to be filtered. Choose any of the following in adding filter.
- For filtering a specific content-type with a corresponding filename, select any option except "*/* (Filter All)" and "- (Unknown Content-type)" from the Content-type list box.
- For filtering all attachments, select "*/* (Filter All)" from the Content-type list box.
- For filtering an attachment given the Content-type, select from the Content-type list box. Content-type can be configured, press the Configure button to modify Content-type option list.
- For filtering attachment given a filename only, select "- (Unknown Content-type)" from the Content-type list box and input a specific filename from the input box.
- Press the Add Button. All the added filters will be displayed in table and filter count will increment. If added filter is */* (Filter All), all the existing filters in the table will be deleted and filter count is equal to 1.
Note: If selected Content-type is */* (Filter All), whatever the content of the filename will be disregarded.
To delete filter(s), do the following:
- Check the corresponding checkbox of a specific filter to be deleted. You may check all the checkbox of the filters that you want to delete.
