Re: [mailop] Compromised email account trends

[John Quaglieri via mailop]

I have seen this trend recently as well. The subject is a utf byte order 
mark which looks blank on an email message or in logs, but not when 
being scanned.  The closest regex I was able to come up with in rspamd 
after many other attempts was

/^.{1}$/u
Which matches a single character utf8 subject.
