11
13 smtpp is SMTP gateway service to allow internal users to access exter‐
14 nal SMTP servers.
15
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.
43
44 -S Increase or decrease stack size. You may want to try something
45 like -S8192 if you experience 3proxy crashes.
46
48 You can use any MUA (Mail User Agent) with SMTP authentication support.
49 Set client to use internal_ip and port as a SMTP server. Address of
50 real SMTP server must be configured as a part of SMTP username. Format
51 for username is username@server, where server is address of SMTP server
52 and username is user´s login on this SMTP server. Login itself may con‐
53 tain ´@´ sign. Only cleartext authentication is supported, because
54 challenge-response authentication (CRAM-MD5, SPA, etc) requires chal‐
55 lenge from server before we know which server to connect.
