mconnect(1) User Commands mconnect(1)NAMEmconnect - connect to SMTP mail server socket
SYNOPSISmconnect [-p port] [-r] [hostname]
DESCRIPTION
The mconnect utility opens a connection to the mail server on a given
host, so that it can be tested independently of all other mail soft‐
ware. If no host is given, the connection is made to the local host.
Servers expect to speak the Simple Mail Transfer Protocol (SMTP) on
this connection. Exit by typing the quit command. Typing EOF sends an
end of file to the server. An interrupt closes the connection immedi‐
ately and exits.
OPTIONS
The following options are supported:
-pport Specify the port number instead of the default SMTP port
(number 25) as the next argument.
-r Raw mode: disable the default line buffering and input han‐
dling. This produces an effect similar to telnet(1) to port
number 25.
OPERANDS
The following operand is supported:
hostname The name of a given host.
USAGE
The mconnect command is IPv6-enabled. See ip6(7P).
