postsrsd - Postfix Sender Rewriting Scheme daemon
postsrsd -s<file> -d<domain> [other options]
Sender Rewriting Scheme implementation for Postfix. Implements two TCP lookup tables to rewrite mail addresses as needed. The forward SRS is for sender envelope addresses to prevent SPF-related bounces. The reverse SRS is for recipient envelope addresses so that bounced mails can be routed back to their original sender.
-s<file> read secrets from file (required) -d<domain> set domain name for rewrite (required) -a<char> set first separator character which can be one of: -=+ (default: =) -f<port> set port for the forward SRS lookup (default: 10001) -r<port> set port for the reverse SRS lookup (default: 10002) -p<pidfile> write process ID to pidfile (default: none) -c<dir> chroot to <dir> (default: none) -u<user> switch user id after port bind (default: none) -t<seconds> timeout for idle client connections (default: 1800) -X<domain> exclude additional domain from address rewriting -e attempt to read above parameters from environment -D fork into background -4 force IPv4 socket (default: any) -6 force IPv6 socket (default: any) -h show usage information -v show version
