EMail Problem mit OE 6 und aon Account

[_m3]

Also laut der Fehlermeldung muss die TO-Zeile länger sein, oder aon hat seinen Mailserver falsch konfiguriert.

Aus der RFC 1893:

X.5.3 Too many recipients

More recipients were specified for the message than could
have been delivered by the protocol. This error should
normally result in the segmentation of the message into two,
the remainder of the recipients to be delivered on a
subsequent delivery attempt. It is included in this list in
the event that such segmentation is not possible.
