Log Message:
mailsrvr: name the rejected address in the sender-auth 550 replies

The 550 reply for an unauthorized MAIL FROM or From: address named only the
address to use instead, never the address that was rejected. The submitter
is left to guess which of the settings in their mail client the server is
objecting to, and only the server log records it -- which the submitter
cannot read.

Seen on Vertrauen: "550 Sender address not authorized for this account, try
<PHARCYDE@vert.synchro.net>" was read as a statement about the server
hostname the client had connected to, and answered with a question about
which hostname to use, when the setting at fault was the sender address.

Grow from_errmsg to 512 bytes: the header 'FROM' message now formats two
addresses of up to 127 characters each, which 256 bytes could truncate.
