WHOM(1)WHOM(1)NAMEwhom - report to whom a message would go
SYNOPSISwhom [-alias aliasfile] [-check | -nocheck] [-draftfolder +folder]
[-draftmessage msg] [-nodraftfolder] [-mts smtp | sendmail/smtp |
sendmail/pipe] [-server servername] [-port port-name/number]
[-sasl] [-saslmech mechanism] [-snoop] [-user username] [-tls]
[-notls] [file] [-draft] [-version] [-help]
DESCRIPTION
Whom is used to expand the headers of a message into a set of addresses
and optionally verify that those addresses are deliverable at that time
(if -check is given).
The -draftfolder +folder and -draftmessage msg switches invoke the nmh
draft folder facility. This is an advanced (and highly useful) fea‐
ture. Consult the mh-draft(5) man page for more information.
The mail transport system default is provided in
/usr/local/etc/nmh/mts.conf but can be overriiden here with the -mts
switch.
If nmh is using the SMTP MTA, the -server and the -port switches can be
used to override the default mail server (defined by the
/usr/local/etc/nmh/mts.conf servers entry). The -snoop switch can be
used to view the SMTP transaction. (Beware that the SMTP transaction
may contain authentication information either in plaintext or easily
decoded base64.)
If nmh has been compiled with SASL support, the -sasl switch will
enable 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 netrc file can be used to store this password,
as described in the mh-profile(5) man page). The -saslmech switch can
be used to select a particular SASL mechanism, and the -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 password.
If SASL authentication is successful, nmh will attempt to negotiate a
security layer for session encryption. Encrypted data is labelled with
`(encrypted)' and `(decrypted)' when viewing the SMTP transaction with
the -snoop switch. The -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.
If nmh has been compiled with TLS support, the -tls and -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
`(tls-decrypted)' when viewing the SMTP transction with the -snoop
switch.
The files specified by the profile entry “Aliasfile:” and any addi‐
tional alias files given by the -alias aliasfile switch will be read
(more than one file, each preceded by -alias, can be named). See
mh-alias(5) for more information.

BUGS
With the -check option, whom makes no guarantees that the addresses
listed as being ok are really deliverable, rather, an address being
listed as ok means that at the time that whom was run the address was
thought to be deliverable by the transport service. For local
addresses, this is absolute; for network addresses, it means that the
host is known; for uucp addresses, it (often) means that the UUCP net‐
work is available for use.
