Thanks, though I actually understood where the problem originated after 
explaining where the email was injected, it was a postfix configuration 
issue (the vacation script has you configure the amavis line in 
master.cf to not expand aliases, so it doesn't send multiple vacation 
replies.. I hadn't considered mail not originating from postfix) , it 
was just that dovecot was the one who had to deal with the error. Thanks 
to Tom Hendrikx for the clue.
