I do not understand this "-t" option. "-t" looks to me like
a Unix shell command parameter. I thought that MUAs
communicated with MTAs for outgoing mail using the SMTP
protocol or a variant of SMTP adapted for communication
between an MUA or the first MTA, and not by using a
unix shell interface.
Not true. Some use SMTP, others call the MTA directly by running the
command /usr/[s]bin/sendmail in a shell interface. (That was, I believe,
the original method, before we had MUAs that ran on PCs.)
Is "-t" an ESTMP facility? How, otherwise, can the MUA tell
the MTA that it wants the MTA to remove Bcc headers from
non-Bcc recipients?
Using SMTP (or the SUBMIT variant), it can't. That's the whole point.
