sendmail, 4th Edition

Ordinarily, when mailstats produces its output, it prints the human-readable names of the delivery agents in its rightmost column:

% mailstats Statistics from Sat Jan 1 17:30:02 2000 M msgsfr bytes_from msgsto bytes_to msgsrej msgsdis Mailer 0 0 0K 246 685K 0 0 prog ... here

If you prefer to omit delivery agent names, you can suppress the last column with this -o command-line switch:

% mailstats -o Statistics from Sat Jan 1 17:30:02 2000 M msgsfr bytes_from msgsto bytes_to msgsrej msgsdis 0 0 0K 246 685K 0 0 ... gone

Note that this -o switch can be combined with the -p switch (described next ) to also suppress printing the M line in that output.
