* Reverts the SMTP regex change in dead3226a545e264072ced40284f86ac41528ba8. (Tim Wojtulewicz, Corelight)
The regex change broke some of the external tests. I added some more cases
to the regular email btest to hopefully cover all of the cases better.
3.3.0-dev.551 | 2020-11-17 15:01:04 -0700
* Added unit tests for regex fix (christina23)
