Are source route paths still used?  After reading the RFCs and IDs,
my impression is that explicit paths in either MAIL FROM or RCPT TO
can be ignored by the SMTP server.  The server can simply use the
local part and domain name.

Is this correct?  It seems much more clear that this is the case
for RCPT TO than for MAIL FROM.  I'd like it to be equally true for
MAIL FROM, but I want to make sure I'm correct and not reading what
I want into what it says.

Do SMTP clients (and servers acting as clients) send explicit
routes (for MAIL FROM or RCPT TO) much these days?  Do servers
need to honor them?
