.SH DESCRIPTION
-.B Post
+.B post
is the default program called by
.B send
to deliver
.B post
which parses the various header fields, appends a
\*(lqDate:\*(rq line, and interacts with the mail transport system.
-.B Post
-will not normally be called directly by the user.
+.B post
+will not normally be called directly by the user,
+but can be replaced by the user with a
+.I postproc
+profile component that will have
+.I file
+as its final argument.
+See the mh-profile(5) man page for more information on postproc.
.PP
-.B Post
+.B post
searches the \*(lqTo:\*(rq, \*(lqcc:\*(rq, \*(lqBcc:\*(rq,
\*(lqFcc:\*(rq, and \*(lqResent\-xxx:\*(rq header lines of the specified
message for destination addresses, checks these addresses for validity,
Not all mail transport systems support this feature.
.PP
The mail transport system default is provided in
-.I %etcdir%/mts.conf
+.I %nmhetcdir%/mts.conf
but can be overriiden here with the
.B \-mts
switch.
.PP
+If nmh is using as its mail transport system
+.BR sendmail/pipe ,
+the
+.B \-sendmail
+switch can be used to override the default
+.B sendmail
+program.
+.PP
If nmh is using the SMTP MTA, the
.B \-server
and the
switches can be used to override the default mail server (defined by the
.RI servers
entry in
-.I %etcdir%/mts.conf
+.I %nmhetcdir%/mts.conf
).
.PP
If
.B \-user
switch can be used to select a authorization userid to provide to SASL
other than the default. The credentials profile entry in the
-mh_profile(5) man page describes the ways to supply a username and
+mh\-profile(5) man page describes the ways to supply a username and
password.
.PP
If SASL authentication is successful,
Encrypted data is labelled with `(sasl-encrypted)' and `(sasl-decrypted)' when
viewing the SMTP transaction with the
.B \-snoop
-switch. The
-.B \-saslmaxssf
-switch can be used to select the maximum value of the Security Strength Factor.
-This is an integer value and the exact meaning of this value depends on the
-underlying SASL mechanism. A value of 0 disables encryption.
+switch.
+Base64-encoded data is wrapped with `b64<>'.
+(Beware that the SMTP transaction may contain authentication information either
+in plaintext or easily decoded base64.)
.PP
If
.B nmh
`(tls-decrypted)' when viewing the SMTP transction with the
.B \-snoop
switch.
+Base64-encoded data is wrapped with `b64<>'.
+(Beware that the SMTP transaction may contain authentication information either
+in plaintext or easily decoded base64.)
The
.B \-notls
switch will disable all attempts to negotiate TLS.
+.PP
+If port 465 is specified and none of the TLS switches were enabled,
+.B \-initialtls
+will be implied if TLS support was compiled in. Though port 465 for
+SMTPS (SMTP over SSL) was deregistered by IANA in 1998, it is still
+used for that service.
+.PP
+.B post
+filters out header lines with names beginning with \*(lqNmh-\*(rq
+(case insensitive) from the message draft.
+Those lines are reserved for internal
+.B nmh
+use.
