I do not need a solution (just sharing information)
Good afternoon!
The problem remains, we can not send emails to our customers (chinatelecomglobal.com, chinatelecomeurope.com, fujitsu.com, vodafone.com, etc)
When sending emails I receive an error:
Remote Server returned '<[195.245.230.51] #5.0.0 smtp; 5.3.0 - Other mail system problem 553-'Message filtered. Refer to the Troubleshooting page at\nhttp://www.symanteccloud.com/troubleshooting for more\ninformation. (#5.7.1)' (delivery attempts: 0)>'
IP addresses of mail servers 62.33.0.2, 62.33.0.3
Several times already sent samples of letters to the address: CLOUDfeedback@feedback-87.brightmail.com
Tell me the reason why our IP addresses are blocked?
