Hello Jonas

The email address of the recipient is added below every
message sent via Apple's mailing lists. This was instated many
years ago (somewhere between 30 August 2004 and 29 October
2004, according to my mail archive). It makes it easier for
mailing list administrators to figure out which subscribed
address is bouncing in case of email forwarding.

Mailman itself is quite good with handling bounces and can suspend (after a soft error has occurred for to long, e.g. mailbox full) or remove subscribers (after hard errors, like user unknown) automatically. An other feature of e-mail helps with this very good. E-mails have two different "From" addresses. One is in the envelope ("Sender:" or "Return-Path:" header line), which proper mail server software (MTA, mail transfer agents) is using for bounces. In case of this mailing list, it is set to 'x11-users-bounces+user=email@hidden' (user=example.com is replaced with your e-mail address, but with = instead of @). So if Mailman is receiving e-mails to this address, it knows which mailing list and which subscribed e-mail address caused the error. The second "From" is the one in the "From:" header line which is displayed and used in your mail client (MUA, mail user agent). On mailing lists this usually is set to the e-mail address of the original sender (e.g. mine), so a private reply could be done easily. On normal private direct e-mails, usually both (envelope and header) "From" are set with the e-mail address which is configured in your MUA. It is even this way until the mailing list server does redistribute (forward) your e-mail to all the subscribers and then is setting a new envelope "From".


PS: Sorry for my two longer off topic postings.


bye
Fabian
