I think it would make sense to change your mail server than your code. Otherwise it's not really been tested.
"intercepting" a command is going to be very awkward at best.
I suppose you could have a MAILX variable, and use $MAILX instead of mailx for your mail command, and alter the variable when your program begins depending on the hostname.

mconnect
mconnect(1) User Commands mconnect(1)
NAME
mconnect - connect to SMTP mail server socket
SYNOPSIS
mconnect [-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:
-p port 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 handling. 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).
FILES
/etc/mail/sendmail.hf help file for SMTP commands
