Commit 356c0754 356c07542f39f1ff159e2646bd97e1791f493aad by Sergey Poznyakoff
Options

Add SMTP test. 

* examples/mta.c: Handle -bD option. Detach from the controlling
terminal if -bd is given. Print pid and port number in this case.
* testsuite/smtpsend.c: Fix handling of the trace= option.
* testsuite/Makefile.am: Add new tests.
* testsuite/smtp-msg.at: New test case.
* testsuite/smtp-str.at: New test case.
* testsuite/testsuite.at: Include new test cases.

2. mta -bd [-p port]
mta -bD [-p port]
Operates as daemon. If port is given, mta will listen on that port.
Otherwise, it will use the first free port in the range 1024-65535.
In this case, mta prints the port number on the stdout, prior to
starting operation. Notice, that in this mode mta does not disconnect
itself from the controlling terminal, it always stays on the foreground.
If the -bd option is given, mta switches to the background and prints
its PID and port number on two separate lines on the stdout. It then
listens for incoming connections for no more than 60 seconds.
If the -bD option is given, the utility prints the port number and
listens for incoming connections not detaching itself from the controlling
terminal.
In any case, at most one connection is served, after which the utility
terminates.

MTA_DOMAIN Sets the default domain name for email addresses. Default
