Altermime breaks with quotes (maybe OT)

I hope altermime author could read this.

Some mail servers sends emails with invalid quoites, like this:

To: Complete Name <'user at domain'>

Look quoites. Postfix works okay with that and it can deal but altermime
breaks. I know this is a bug of altermime, but I wonder if there is a way to
workarround this with postfix.

TIA
