From with missing space

[Joseph Brennan <br...@columbia.edu>]

Did you ever notice this, especially in phishing spam?
From: "LAFCU"<la...@cardserv.com>

That is, no space between the " and the < signs.
header FROM_NOSPACE    From =~ /\"</

I haven't found any legit mail with this format.  Would anyone else
like to check?

Seeing a missing space there is not uncommon in spams, although it is (or 
historically hasn't been) hugely common either.  I had a rule for it once 
when a particular spam tool was being rather vociferous in that way.

I have seen this in legit mail from things like webmail systems, but it is 
fairly rare.
