Mail Monitor: regular expressions - Queries / Submissions

Submitted regular expression.

Sometimes, it looks like the subject of spam messages has been randomly created, i.e "wtsyuw", "ptrvwik", etc etc.
It is fairly tricky to catch them all just using the subject field, but here is a simple condition to flag the ones that do not contain a vowel ("kndwvw", "zxtcx",...)

If the subject does not contain regular expression:

Code:

[aeiouy]+

If the subject doesn't contain at least one "a", "e", "i", "o", "u", or "y", it will be flagged.
