What is RegExp?
See short description of Regular Expressions here.
Using regexp in filters
You can define filter to catch messages, which include regexp sequence in certain field.
To do this, select Includes RegExp filter condition, and type your RegExp in text field.
Sample RegExp filters:
To detect multiple spaces in subject: \s{5,}
To detect Viagra clones: V.AGRA
Case sensivity
Like all other filters, RegExps are not case sensitive by default.
To make RegExp matching case sensitive, use this syntax: /regexp/
Example: /\u{3,}/ expression will match 3 or more capital letters in sequence.
Testing RegExps
Creating an effective RegExp could quite a complex task, especially if you have not used it before. To test you
expressions we have added special RegExp tester. There you can enter a test string and
regular expression you want to match and verify that everything is working as expected. You will find tester under Help/Test RegExp menu.
For your convenience you will find also there a quick reference of RegExp entries.
