Re: Why is there a punctuation "rule" ?

It's not a bug so much as a feature... :)

Actually, I knew the characters are allowed for the spec, I had just never 
seen them used in anything but spam.  Many spammers seem to do wierd things 
to their from addresses (like having leading or trailing spaces or extra 
uncommon punctuation) that real mailers have trouble handling when you try 
to bounce undelivered messages back.  So I included a rule to filter them 
out so secondary mx's never have to deal with them in the first place.

If you want to disable these and other address formatting checks, just 
change $check_envelope_address_format to equal zero in your config.
