I am trying to pick out all the Email addresses from the sample data below:

USER:Peter Pan
EMAIL:email@email.com
EMAIL:email1@email.com
EMAIL:email2@email.com
EMAIL:email3@email.com
EMAIL:email4@email.com
EMAIL:email5@email.com
USER:Bob Scott
EMAIL:email@email.com
EMAIL:email1@email.com
EMAIL:email2@email.com
EMAIL:email3@email.com
EMAIL:email4@email.com
EMAIL:email5@email.com
USER:Tomas Uncle
EMAIL:email@email.com
EMAIL:email1@email.com
EMAIL:email2@email.com
EMAIL:email3@email.com
EMAIL:email4@email.com
EMAIL:email5@email.com

Now this regex with rex works fine and picks up all the email addresses

rex field=_raw max_match=15 "EMAIL:(?<test>.*?)\n"

But how do i specify in transforms.conf to match multiple times??

There is no max_match option for transforms.conf
Here is my transforms.conf

[get-emails]
REGEX = ^EMAIL:(.*?)\n
FORMAT = Emails::$1

As you can see i tried both types of supported regex's in the transforms.conf file.

Any ideas?

You can use the MV_ADD option in your transforms stanza:

[get-emails]
REGEX = EMAIL:(\S+)
FORMAT = Emails::$1
MV_ADD = true
