DESCRIPTION

13       smtpp is SMTP gateway service to allow internal users to access  exter‐
14       nal SMTP servers.
15

OPTIONS

17       -I     Inetd mode. Standalone service only.
18
19       -d     Daemonise.  Detach  service  from  console  and run in the back‐
20              ground.
21
22       -t     Be silenT. Do not log start/stop/accept error records.
23
24       -u     Never look for username authentication.
25
26       -e     External address. IP address of interface proxy should  initiate
27              connections  from.   By default system will deside which address
28              to use in accordance with routing table.
29
30       -i     Internal address. IP address proxy accepts connections  to.   By
31              default  connection  to  any interface is accepted. It´s usually
32              unsafe.
33
34       -p     Port. Port proxy listens for incoming  connections.  Default  is
35              25.
36
37       -h     Default  destination.  It's used if targed address is not speci‐
38              fied by user.
39
40       -l     Log. By default logging is to stdout. If  logfile  is  specified
41              logging  is to file. Under Unix, if ´@´ preceeds logfile, syslog
42              is used for logging.

CLIENTS

45       You can use any MUA (Mail User Agent) with SMTP authentication support.
46       Set  client  to  use  internal_ip and port as a SMTP server. Address of
47       real SMTP server must be configured as a part of SMTP username.  Format
48       for username is username@server, where server is address of SMTP server
49       and username is user´s login on this SMTP server. Login itself may con‐
50       tain  ´@´  sign.   Only  cleartext authentication is supported, because
51       challenge-response authentication (CRAM-MD5, SPA, etc)  requires  chal‐
52       lenge from server before we know which server to connect.
