Rewrites the envelope sender address in view of remailing it
envfrom2srs [fwdomain] email
Rewrite the email with an SRS encoded version. fwdomain is used as forward domain.
WARNING:
Use only if absolutely necessary. It is very inefficient and a security risk.
The program uses /etc/mail/pysrs.cfg, if available:
[srs] secret = 'shhhh!' maxage = 8 hashlength = 8 fwdomain = 'mydomain.com' separator = '='
