 This involves adding a couple of functions to rewrite outgoing return paths in 'relayout.lua' or 'mxout.lua' as appropriate and a couple of functions to redirect rewritten bounce message recipients in 'smtpsvr.lua'
+In earlier versions of VPOP3 (or if you don't want the bounce-redirection function of SRS), you can use basic Sender Rewriting using the 'Return path Settings' tab of the Mail Sender in the VPOP3 settings. Set 'SMTP Return Path:' to 'If the original address is not local, set to', and enter a local email address which won't have forwarding or autoresponders set - eg postmaster@yourdomain.com
 The below is a basic implementation based on https://www.libsrs2.net/srs/srs.pdf
