A childhood friend of mine have this problem:
He can send mails to his mailing list server only with RoundCube, but
with another Client[Squirrelmail, Thunderbird, ClawsMail or Micro$oft
Outlook doesn´t], and I don´t know what´s happening. I post below his
main.cf. Mailman if configured and working, when you send a mail to a
list, postfix give a user "unknown error"[the user of the list], but
with RoundCube works as a sunshine. So I don´t know what might be
happening there.
I hope you can help me because the issue is tricky to me too.
