How do I configure Claws (under Windows 8) so that I can send email via
SMTP? Receiving is no problem, but sending a mail appears to be impossible.
Both GMX as well as Arcor end up with this error:
[21:15:11] SMTP< 554 5.7.1 <unknown>: Helo command rejected: EHLO Unknown
** Fehler bei der SMTP-Sitzung
*** Fehler beim Senden der Nachricht:
554 5.7.1 <unknown>: Helo command rejected: EHLO Unknown exploit
I tried various options and looked up the FAQ but can't find anything. I am
using the same accounts in MS Outlook without any issues.
If it is hostname related, "hostname" returns a valid hostname.
Any further ideas?
