When you use of the e-mail facilities of Carerix and as a part of these facilities, you have e-mails automatically forwarded from Carerix to your own e-mail address.
Forwarding the mails is turned off, and you see the message below:
"Subject: Forwarding e-mail for user ... failed
When forwarding the e-mail to ... an error occurred. Forwarding the e-mail is turned off.
Check if the e-mail address is correct"
It can occur that an e-mail that Carerix forwards, comes back immediately. This way you can get a mail-loop if Carerix does not turn the automatic forwarding off.
Reasons that an e-mail comes back:
The e-mail address doesn't exist (anymore).
Every forwarded e-mail results in a 'bounce'
The mail server doesn't react or doesn't accept mails from Carerix.
The mail results in a 'bounce'.
The receiving mailbox has set an "out-of-office" message.
This will send a reply on every incoming mail.
Check, based on the points above, if the receiving e-mail is working and doesn't lead to an automatic reply. If everything is correct, you can turn the functionality back on.
