How would you implement the section here titled "Sendmail workaround" using 
Postfix? I use a lot of plussed addresses with the plus replaced with dot 
to deal with broken websites that reject a plus sign in an address. All my 
website logins use plussed addresses with dots. (I also use an email alias 
so my email address isn't my imap login.)
