11                [ -r realm ] [ -f file ] [ -n num ] [ -s ] [ -c ]
12                [ -i ] [ -o option=value ] [ -v ] hostname

DESCRIPTION

15       pop3test  is a utility that allows you to authenticate to a POP3 server
16       and interactively issue commands to  it.  Once  authenticated  you  may
17       issue  any POP3 command by simply typing it in. It is capable of multi‐
18       ple SASL authentication mechanisms and handles encryption layers trans‐
19       parently.  This  utility  is  often used for testing the operation of a
20       pop3 server. Also those developing POP3 clients find it useful.

OPTIONS

23       -t keyfile
24              Enable TLS.  keyfile contains the TLS public and  private  keys.
25              Specify  ""  to negotiate a TLS encryption layer but not use TLS
26              authentication.
27
28       -p port
29              Port to connect to. If left off this defaults to pop3 as defined
30              in /etc/services.
31
32       -m mechanism
33              Force pop3test to use mechanism for authentication. If not spec‐
34              ified the strongest authentication mechanism  supported  by  the
35              server is chosen.  Specify user to use the USER/PASS commands or
36              apop to use the APOP command instead of AUTH.
37
38       -a userid
39              Userid to use for authentication; defaults to the current  user.
40              This  is  the  userid whose password or credentials will be pre‐
41              sented to the server for verification.
42
43       -u userid
44              Userid to use for authorization; defaults to the  current  user.
45              This  is the userid whose identity will be assumed after authen‐
46              tication.  NOTE: This is only used  with  SASL  mechanisms  that
47              allow proxying (e.g. PLAIN, DIGEST-MD5).
48
49       -k num Minimum protection layer required.
50
51       -l num Maximum protection layer to use (0=none; 1=integrity; etc).  For
52              example if you are using the KERBEROS_V4  authentication  mecha‐
53              nism  specifying  0 will force pop3test to not use any layer and
54              specifying 1 will force it  to  use  the  integrity  layer.   By
55              default the maximum supported protection layer will be used.
56
57       -r realm
58              Specify  the  realm  to  use.  Certain authentication mechanisms
59              (e.g. DIGEST-MD5) may require one to specify the realm.
60
61       -f file
62              Pipe file into connection after authentication.
63
64       -n num Number of authentication attempts; default = 1.  The client will
65              attempt  to  do  SSL/TLS  session reuse and/or fast reauth (e.g.
66              DIGEST-MD5), if possible.
67
68       -s     Enable POP3 over SSL (pop3s).
69
70       -c     Enable challenge prompt callbacks.   This  will  cause  the  OTP
71              mechanism  to  ask  for the the one-time password instead of the
72              secret pass-phrase (library generates the correct response).
73
74       -i     Don't send an initial client response for SASL mechanisms,  even
75              if the protocol supports it.
76
77       -o option=value
78              Set the SASL option to value.
79
80       -v     Verbose. Print out more information than usual.
