Hi Joe,

The mailing list you mentioned got filtered out. Can you repeat it without the @?

I couldn’t get it to work until I changed the regex to [^\.]*.*

I think the issue is [^\.] means any character, except ., exactly once. You can see this on
regex101 (dot com).

If this is an issue, it also shows up in the ListFile processor.

Thanks,

Greg

Greg,

[hidden email]</user/SendEmail.jtp?type=node&node=12711&i=0> is probably better
but this is just fine.

My regex foo gets weaker by the day.  But I believe the regex says
"avoid things that start with '.' but accept anything else".

Looking here https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html

The [^ starts a character class as a negation of those characters.
And the .* says any character (typically excluding newlines) and any
number of them 0 or more.

Have you verified that it is not working?

Thanks
Joe
