The forum script [link=https://github.com/ilosuna/mylittleforum/blob/2.4.24/includes/functions.inc.php#L2377]does the stitching of the forum name and e-mail-address by itself[/link].

> The questionable setting above led to an invalid From-header. The header field [inlinecode]From[/inlinecode] contains a comma separated list of e-mail-adresses ([inlinecode]From: info@example.com[/inlinecode]) or mailboxes ([inlinecode]Forum <info@example.com>[/inlinecode]). Your forum name stands alone for itself and breaks the necessary format. It must be: [inlinecode]Forum <info@example.com>[/inlinecode], but is (according to your posting): [inlinecode]Forum name <Forum <info@example.com>>[/inlinecode].
> 
> That's documented in your own example. We will inspect it from outer to inner side. The next code block contains the whole content of the From-header. The first two addresses got added [i]after[/i] delivering the e-mail with the function [inlinecode]mail[/inlinecode] to the mail relay of your provider.

> This is a second possible problem. The (old, long) name contains commata. Commata separates the entries in the From-header, so the From-header contains the following sender entries (not encoded):

> The senders [inlinecode]Forum[/inlinecode] and [inlinecode]nicht öffentlich[/inlinecode] are invalid, the last entry [inlinecode]nur für Mitglieder <Forum <info@domain.de>>[/inlinecode] anyway. I would expect the forum name to be safe because of its encoding. But it not seems to be so.
