Summary0001588: No e-mails can be sent from cacert.org sender address
DescriptionWhile sending an e-mail to an e-mail-address from a cacert.org sender address with an e-mail-programm, I get the followiing error message:
-----------------------------------------------------------
Senden der Nachricht fehlgeschlagen.
Fehler beim Senden der Nachricht: Der Mail-Server antwortete:
<myname@cacert.org>: Sender address rejected: not owned by user myname.
 Bitte überprüfen Sie die E-Mail-Adresse des Empfängers "hisname@hisprovider.de" und wiederholen Sie den Vorgang.
-----------------------------------------------------------
The same happens to all other e-mail addresses, even @cacert.org

If there are more than one address in the e-mail, in the error message is shown only the first one. If I remove that one and try to send again, the next one is mentioned in the error message, etc. etc.

Nota: Receiving works well.

Today finally sending from cacert.org addresses worked again, but it was not possible to send e-mails to cacert.org-lists. See the following mailer daemon message:
(for better understading: xxx@cacert.org is the owner of this list.)

sending to lists.cacert.org addresses does still not work from an e-mail client. From the web form it does.

I can confirm this behavior.

My guess is that CAcerts SPF record "v=spf1 a mx a:emailout.cacert.org a:secure.cacert.org a:www1.cacert.org a:ping.cacert.org ip4:213.154.225.230 ip6:2001:7b8:616:162:1::10 ip6:2001:7b8:616:28:50::11 -all" does not include the internal (IP) address of email.cacert.org, probably something like 10.0.10.xxx

It is now three month since note https://bugs.cacert.org/view.php?id=1588#c6360 and we can still not send e-mails from an cacert-e-mail-adress to a cacert mailing list. Every mail I answer e.g. o the support list goes to the sender, but the copy to the list, I have to copy paste to the sympa server and send it there a second time. This is just waist of time. This way, we will never find more people to give a hand.
