Hello there,
as similar stated in several other posts I have an issue with sending emails to messagecloud users from our dedicated server. We are using the swift mailer built in in TYPO3 for sending system mail notifications to our customers. One of our customers delivered us a mail of this kind:
Delivery has failed to these recipients or groups: XXXX@XXX.XXX A problem occurred while delivering this message to this email address. Try sending this message again. If the problem continues, please contact your helpdesk. The following organization rejected your message: cluster8.eu.messagelabs.com.
I don't know if it has something to do with our IP address, but I would like you to check, therefore we can either do something about it or search for another solution. Our ip address is 134.119.134.252
Thanks in advance and let me know if I can do something at our end.
Best regards
Robert
