Alligate can use complex Regular Expressions (Regex) to analyze the senders HELO/EHLO command to trigger greylisting if a matching pattern is found. You can optionally define a Regex statement to except certain patterns from triggering greylisting.

 

Test HELO command for Regex matches EXCEPT matches to the following expression: There are some HELO values that indicate the likelihood the message is coming from a valid sender is very high. If the HELO value matches this Regex definition the HELO will not be subjected to any further testing. If you use the HELO settings Wizard, this will be filled in automatically for you. We recommend that you do not change this setting unless you have a particular need.

 

Skip this test if the sender is an MXRate "Good Sender": This will cause Alligate to skip HELO testing when MXRate reports the sending server as being a good sender.

 

Test all other HELO commands for Regex matches: This section allows you to define multiple HELO Regex tests to use to check the HELO value for indications that the message may be originating from a suspicious computer. If you use the HELO settings Wizard, this will be filled in automatically for you. These default settings are based on research done by Matt Bramble from MailPure, an Alligate "Power user". We recommend that you do not change this setting unless you have a particular need.

 

If a Regex match is found, add xx seconds to tarpit penalties. (0=disabled): This setting allows you to also add additional tarpit penalty seconds if a suspicious HELO value is found.
