NAME¶
smtpprox-loopprevent - Transparent SMTP proxy to prevent mail forwarding loops
SYNOPSIS¶
smtpprox-loopprevent [
options] listen.addr:port talk.addr:port
DESCRIPTION¶
This manual page explains the
smtpprox-loopprevent program.
smtpprox-loopprevent is a transparent SMTP proxy which rejects a message
message if any of the recipient addresses (
Rcpt To:) match a
Delivered-To: header.
smtpprox-loopprevent listens on the
listen.addr:port address and
port and sends smtp traffic unmodified to the SMTP server at
talk.addr:port.
smtpprox-loopprevent was written to be a Postfix before-queue content
filter, but will function between any SMTP client and server.
OPTIONS¶
- --children=N
- The number of child processes to maintain in the service pool. Each child
terminates after servicing a random number of messages between
minperchild and maxperchild.
[default 16]
- --minperchild=N
- Minimum number of messages serviced by a child process.
[default 100]
- --maxperchild=N
- Maximum number of messages serviced by a child process.
[default 200]
- --debugtrace=filename_prefix
- If debugtrace is specified, the prefix will have the PID appended
to it for a separate logfile for each child, which will capture all the
SMTP dialogues that child services. It looks like a snooper on the client
side of the proxy.
