Hi Peter,

Further to Joerg's comments, are you sure the From header is *exactly* 
RFC5322 compliant in all cases?

I notice that people have had problems where servers have previously 
been tolerant before, of e.g. spaces inside the angle brackets or 
comments on the RHS, and are now tightening up their parsing.

I'm assuming this is low-hanging fruit to weed out some of the more 
casual spammers.

Also check line endings, and maximum line length (although you say it's 
happened with short emails, so this seems unlikely).

Can you capture the *exact* data that was sent out by your system, and 
then give one as an example of the formatting, blanks included, with 
names (emails) changed to protect the innocent?

Can you highlight the specific SMTP sending code you're running?
