the official documentation of postfix can be found on
http://www.postfix.org/documentation.html
for the man pages, click on "All Postfix manual pages", which leads you to
http://www.postfix.org/postfix-manuals.html
and for all postfix parameters, click on "All main.cf parameters", which
leads you to
http://www.postfix.org/postconf.5.html

the domain is never empty. (unless you configure postfix not to append

${nexthop} can be set by you in a transport entry.

if using postfix 2.5 or higher (the variable didn't exist before).

well, the risk is if you change the extension delimiter in postfix but
dovecot keeps using '+'. I prefer to handle the extension in postfix and
pass it via -m to dovecot.
