NAME
smtptest - interactive SMTP test program
SYNOPSIS
smtptest [ -t keyfile ] [ -p port ] [ -m mechanism ]
[ -a userid ] [ -u userid ] [ -k num ] [ -l num ]
[ -r realm ] [ -f file ] [ -n num ] [ -s ] [ -c ]
[ -i ] [ -o option=value ] [ -v ] hostname
DESCRIPTION
smtptest is a utility that allows you to authenticate to a SMTP server and interactively issue commands to it. Once authenticated you may
issue any SMTP command by simply typing it in. It is capable of multiple SASL authentication mechanisms and handles encryption layers
transparently. This utility is often used for testing the operation of a smtp server. Also those developing SMTP clients find it useful.
OPTIONS
-t keyfile
Enable TLS. keyfile contains the TLS public and private keys. Specify "" to negotiate a TLS encryption layer but not use TLS
authentication.
-p port
Port to connect to. If left off this defaults to smtp as defined in /etc/services.
-m mechanism
Force smtptest to use mechanism for authentication. If not specified the strongest authentication mechanism supported by the server
is chosen.
-a userid
Userid to use for authentication; defaults to the current user. This is the userid whose password or credentials will be presented
to the server for verification.
-u userid
Userid to use for authorization; defaults to the current user. This is the userid whose identity will be assumed after authentica-
tion. NOTE: This is only used with SASL mechanisms that allow proxying (e.g. PLAIN, DIGEST-MD5).
-k num Minimum protection layer required.
-l num Maximum protection layer to use (0=none; 1=integrity; etc). For example if you are using the KERBEROS_V4 authentication mechanism
specifying 0 will force smtptest to not use any layer and specifying 1 will force it to use the integrity layer. By default the
maximum supported protection layer will be used.
-r realm
Specify the realm to use. Certain authentication mechanisms (e.g. DIGEST-MD5) may require one to specify the realm.
-f file
Pipe file into connection after authentication.
-n num Number of authentication attempts; default = 1. The client will attempt to do SSL/TLS session reuse and/or fast reauth (e.g.
DIGEST-MD5), if possible.
-s Enable SMTP over SSL (smtps).
-c Enable challenge prompt callbacks. This will cause the OTP mechanism to ask for the the one-time password instead of the secret
pass-phrase (library generates the correct response).
-i Don't send an initial client response for SASL mechanisms, even if the protocol supports it.
-o option=value
Set the SASL option to value.
-v Verbose. Print out more information than usual.
