.SH DESCRIPTION
.B Post
.B post
which parses the various header fields, appends a
\*(lqDate:\*(rq line, and interacts with the mail transport system.
-.B Post

+.B post
+will not normally be called directly by the user,
+but can be replaced by the user with a

+profile component that will have
+.I file

.B Post
searches the \*(lqTo:\*(rq, \*(lqcc:\*(rq, \*(lqBcc:\*(rq,
Under normal circumstances,
.B post
uses the \*(lqFrom:\*(rq line in the message draft as the identity of
-the the originating mailbox. A \*(lqFrom:\*(rq line is required in
+the originating mailbox. A \*(lqFrom:\*(rq line is required in
all message draft. By default the message composition utilities such
as
.BR comp ,
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

the use of SASL authentication with the SMTP MTA. Depending on the
SASL mechanism used, this may require an additional password prompt from the
user (but the
-.RI \*(lq \&.netrc \*(rq
-file can be used to store this password).
+.I netrc
+file can be used to store this password, as described in the
+mh-profile(5) man page). The
.B \-saslmech
switch can be used to select a particular SASL mechanism,

Encrypted data is labelled with `(sasl-encrypted)' and `(sasl-decrypted)' when

+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
has been compiled with TLS support, the
.B \-tls
and
-.B \-notls
-switches will require and disable the negotiation of TLS support when
-connecting to the
-SMTP MTA. Encrypted data is labelled with `(tls-encrypted)' and
+.B \-initialtls
+switches will require the negotiation of TLS when
+connecting to the SMTP MTA. The
+.B \-tls
+switch will negotiate TLS as part of the normal SMTP protocol
+using the STARTTLS command. The
+.B \-initialtls
+will negotiate TLS immediately after the connection has
+taken place, before any SMTP commands are sent or received. Encrypted data
+is labelled with `(tls-encrypted)' and
`(tls-decrypted)' when viewing the SMTP transction with the

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.
