Regex Pattern match, but doesn't work in productio

   I have a trigger that uses a regex pattern of “[a-z]*$” which is supposed to match any number of lowercase letters at the end of the line. For example, in emails that are parsed, I need to match the last few letters in the last line of an email such as “Groupname: prod-vm.cluster.sjc”. in the aforementioned example, “sjc” is a match, but in production, it fails to match anything.

If I create or edit the trigger and paste the contents in the box, the regex pattern will show as a match.
If I use the “Run with” option within Email2DB and paste the contents of the email it will work as expected.
 If I use the smtptest.exe program in the program files directory of email2db, it fails to match the data as well as any production emails.

I can reproduce the problem by creating a new trigger with a basic single line as the body of an email and apply the same regex.  At the moment, it appears that if I create any regex that uses the “$” to anchor a pattern to the end of the regex will appear to work when creating or editing trigger, but fails to parse any information once in production.

Any ideas as to what I may be doing wrong?

	Problem Solved. Liam provided me with information which pointed out the multiple CRLF's at the end of the email message were causing the regex to not match correctly. To compensate for this I changed the regex to [a-z][\r\n]$ which correctly targets the string of letters and takes into consideration one or more CRLFs at the end of the email. Thanks Liam!!!
