SYNOPSISlmtptest [ -t keyfile ] [ -p port ] [ -m mechanism ]
[ -a userid ] [ -u userid ] [ -k num ] [ -l num ]
[ -r realm ] [ -f file ] [ -n num ] [ -c ]
[ -i ] [ -o option=value ] [ -v ] hostname
DESCRIPTIONlmtptest is a utility that allows you to authenticate to a LMTP server
and interactively issue commands to it. Once authenticated you may
issue any LMTP command by simply typing it in. It is capable of multi‐
ple SASL authentication mechanisms and handles encryption layers trans‐
parently. This utility is often used for testing the operation of a
lmtp server. Also those developing LMTP 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 lmtp as defined
in /etc/services.
-m mechanism
Force lmtptest to use mechanism for authentication. If not spec‐
ified 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 pre‐
sented 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 authen‐
tication. 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 mecha‐
nism specifying 0 will force lmtptest 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.
-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.
