# envfrom2srs(1)

rewrites the envelope sender address in view of remailing it

## NAME

envfrom2srs - rewrites the envelope sender address in view of remailing it

## SYNOPSIS

*envfrom2srs* \[*fwdomain*\] *email*

## DESCRIPTION

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.

## CONFIG FILE

The program uses */etc/mail/pysrs.cfg*, if available:

```
[srs]
secret = 'shhhh!'
maxage = 8
hashlength = 8
fwdomain =  'mydomain.com'
separator = '='
```
