We are getting blocked when trying to send emails to all customers that have symantec or broadcom, we have contacted the individual users and they said we had to contact symantec and get it unblocked directly from them. Our domain name is bandagist.nu and we have recently moved from bandagist-centret.dk but it doesn't matter which domain we send from it is still blocked. Here is an excerpt of a mail that has been blocked, we have been blocked for a few weeks now and I have a lot of angry coworkers that need to send emails but are unable to. If you need further info such as IP address or other please let me know.
