Mail from isp gets rejected or marked as spam
Hi,
A couple of days ago, we noticed that mails sent from a certain isp (@telenet.be) got rejected.
After turning off the content filtering the mails are being recieved but marked as spam.
I turned on smtp logging and tested mails from that isp (telenet.be) and my own (@techne.be) and they are both recieved the same way (see code, extract from smtplog)
When i telnet to the mailserver, i get a message (see screenshot) using the telenet account, but when i use the techne account i get the same message.
Thanks in advance
