Thanks for the details!

This is ironic. A couple of 'extra' headers in the email notifications
from Ringlink are there in order to discourage it from being used for
spam or other forms of abuse:

    Sender:            The 'real' sender, in this case the address
                       of the system administrator

    X-Originating-IP:  The IP address of the ISP where the person
                       who initiates the message is logged in.

I deleted 3 members from the ring. The ringmaster mail-copy's sent to my Hotmail mailbox for all 3 was put in the spamfolder.

It should be noted that the ringmaster copy of a delete message is a bcc copy. One thing that might be worth testing is to change it to a cc copy. This can be done in 'sub email' in rlmain.pm (or in Ulf's case in gentools.pm).

Has also noticed that if mail-delivery-error (host unknown, no account etc) and the ringlink mail is returned as attachment;

Such return messages are composed by your mail server, not by Ringlink.

Outlook Express removs access to the attachment (= mail sent from ringlink) as not safe.

To me that sounds like an OE configuration thing.

Can it be someting in the mail-header, that makes Hotmail think it is spam and OE that it is unsafe?

Don't know. See above about the extra headers added by Ringlink.

I notice that in the mail-header Return-Path, From and Sender is not the same: From: ringmaster@xxxx Sender: adminemail@xxxxxxxxxxxxxx Return-Path: my_accont_name@xxxxxxxxxxxxxxxxx (not my domain) This puts all mail-delivery-error in my catch_all_mailbox.

That's correct. "From:" is the logical sender, e.g. the ringmaster address, while the "Sender:" always is the system administrator address (see above). As regards "Return-Path:", what you mentions here tells me that your Ringlink installation sends the messages via sendmail, and accordingly "Return-Path:" is controlled by the sendmail configuration. If you switch to the SMTP option, the address in the "Return-Path:" header will equal the "From:" address. (Btw, this makes the SMTP option the better alternative IMO.)

It would be interesting to know whether changing from 'bcc' to 'cc',
as suggested above, makes a difference. Feel free to contact me privately.
