Hello.
Our company experience problems with sending mail to diffrerent receiptents wotj Symantec Spam Protection System.
Previously we used dynamic IP address, now I switched it to static and our permanent address is: 95.84.162.5
Coudl you please kindly add it to white list and remove from blocked list?
Our company works and use this address more than 20 years and after changing ISP now it is impossible to work with part of our customers.
