The reason is strong. A quote from submitter:
In current state choose of native or nullmailer's
sendmail/mailq depends on order of paths in $PATH
instead of sysadmins choose. (/etc/mail/mail.conf in general case)

After this patch, the action of piping mails out won't stop,
even if all of your mails were failed to deliver. Nullmailer
itself will keep throwing mails to smart relay as long as
there're incoming mails, no matter how broken the recipients
of the previous mails.
Still leave this port in FORBIDDEN state until I address

If you want to create a file, visit that file with C-x C-f,
then enter the text in that file's own buffer.
Add nullmailer, a sendmail compatible MTA which only does one thing:
send mail to a SMTP or QMQP smart relay.
NOTICE: This port is usable now, but not yet dumb-safe. Please pay
attention on its pkg-message.
