Phishing emails cause MailScanner to loop infinitely

[Anthony Peacock]

Hi Jeff,

I had forgotten about your earlier email, I think I had got sidetracked 
by the discussion about the Web Bug URL...

I have gone back through the archives and re-read your emails, and I 
agree this sounds like the same issue.

I am wondering if it is an issue with the Df routines under Solaris...
