Hello naudefj,

You are right about the proposed preg_replace, slashes were missing.

But I beleive the original code to be wrong about the Return-Path and Errors-To headers.

1) The Return-Path header should consist of an angle-address only, and not « name + angle-address » as in From header.

<https //datatracker.ietf.org/doc/html/rfc2822#section-3.6.7>
§
return = "Return-Path:" path CRLF

path = ([CFWS] "<" ([CFWS] / addr-spec) ">" [CFWS]) /
obs-path
§

2) The Errors-To header is non standard and discouraged, it shouldn't be set at all.

<https //datatracker.ietf.org/doc/html/rfc2076.txt#section-3.5>
§
Address to which notifications Errors-To:, Non-standard,
are to be sent and a request to Return- discouraged.
get delivery notifications. Receipt-To:
Internet standards recommend,
however, the use of RCPT TO and
Return-Path, not Errors-To, for
where delivery notifications are
to be sent.
§
(oups, it is unreadable, even with font=Courier... read the original RFC instead)

Regards,
Olivier Miakinen
