smtp.kpn-officedsl.nl Mail rejected

smtp.kpn-officedsl.nl Mail rejected
 
Recently the following message started to appear when sending email through KPN.
 
Server Response: '550 5.0.0 Mail rejected.' (Account: 'info', SMTP Server 'smtp.kpn-officedsl.nl', Error Number: 0x800ccc69).
 
The KPN help desk doesn not understand the description of the problem I have given them. Their solution: always use a kpn return address (me@kpn.nl). However I am sending emails to customers and wish to use my own domain to receive email (me@mydomain.nl).
 
It does not happen for all emails. Just for some.

Sending small attachments proves to be problematic now. I send small 200 bytes or so text attachments as key.txt along with emails to customers. As of mid February they are rejected...
 
I did find a customer representative who looks into the problem for me...

smtp.kpn-officedsl.nl rejects the word hyperlink
 
When asked KPN tells customers that outgoing emails sent through their smtp.kpn-officedsl.nl webserver is not scanned. However it is! When I enter the following text in an email body the email will be rejected by the smtp server:
purchase it online using this hyperlink
 
When I remove the word hyperlink the message is sent correctly. It is all still under investigation, or so I hope.
 
Outlook reports the error upon sending as follows:
Server Response: '550 5.0.0 Mail rejected.'. (Account: 'info', SMPT Server:
'smtp.kpn.officedsl.nl', Error Number: 0x800ccc69
