Filtering In Staff Webmail
You can set filters to move or delete messages with specified information. Webmail also has a blacklist service, which is a kind of filter.
Setting a Filter
Create a filter by going to Options | (Mail Management) Filters and selecting Edit your filter rules. The window opens in which you set rule criteria. Select the field Webmail should filter on: To, CC, From, Subject, or Body. Then enter the Text that Webmail should search for in that field. Finally set the Action, delete or move the message to a specific mail folder.
You can select multiple fields to filter messages. For example, if you select Subject and Body with the text “Make Money”, messages that include that exact phrase in either the subject line or the body will be filtered according to the rule. Notice that rules are case sensitive. In the above example, a message with the text “Make money” would not be filtered by this rule.
If you have set Webmail to move deleted messages to the Trash, messages you filter to delete are moved to the Trash. If the filter action you select is move, you must select the folder you want messages moved to, and that folder must be created prior to creating the filter.
After setting the filter rule definition, click the Create button. The rule appears under the Filter Rules above the Rule Definition. To apply the filters, click the Apply All Rules button.
Modify a RuleTo modify a filter rule, select the rule under Filter Rules by clicking the radio button to the left of the rule. The Rule Definition options change to Modify, Reset, and Cancel. Make the desired changes in the rule and click the Modify button.
Delete a RuleTo delete a filter rule, select the rule under Filter Rules by clicking the radio button to the left of the rule and click the Delete button.
Filter Rules and Order
Rules run in the order listed under Filter Rules. You could create rules that would affect the same message differently, so once rules are created, pay attention to the order in which they are processed. The rules are processed in ascending order, the rule labeled “1)” first, and so on. To move a rule up or down the order list, click the radio button to the left of the rule and then click the Move Down or Move Up button.
Filters can run when you log in and/ or when a mailbox is refreshed. There is also an option to display a message when filters have been applied. Select this option to see what messages were filtered and what was done with them. The information appears at the top of the mailbox screen (as shown).
To run the filters at any other time, with a folder open, click the Apply All Rules button next to the folder name.
Leave the window by clicking Save Options.
You can blacklist mail coming from a specified sender. To blacklist an address, from the Inbox click the box in front of a message from that address, and then click Blacklist at the top of the column. The filter rules open and you’ll see the last rule is to delete message from the selected From. When you blacklist an address, all future messages from that address will be deleted automatically.
Spammers rarely use the same address each time, so blacklisting is unlikely to catch spam.
Filter & Blacklist Limitation
Webmail allows only 4,000 characters for filters, which include blacklisted addresses. If you try to add a filter and get an error (A fatal error has occurred. DB Error : unknown), you have reached your 4,000-character limit. You must delete existing filters to be able to add a new one. Unfortunately, there is no way to determine how many filters will fit in the 4,000-character limit, because not all filters have the same number of characters. In addition, Webmail uses some characters to encode the filter list.
