Unless properly quoted. Following address is an invalid address:

It should be quoted:
rcpt to:<"noahm+foo nlm"@???>
Here I connect to incoming.csail.mit.edu:

As you wish... I do not want to start discussing that. After all, that
is your system .:)
Another router came into my mind today. Map file will be of the format:
user1: user2@???
Router:
redirect:
driver = redirect
domains = ...
local_parts = dbm;/path/to/map.db
local_part_suffix = +*
local_part_suffix_optional
data = ${quote:\
${local_part:$local_part_data}$local_part_suffix\
}@${domain:$local_part_data}
That is much cooler that the previous suggestion, IMHO. There is more
than one way to do it. :)
