I need a solution
Hello,
2 of our customers have problems sending mails messagelabs.com servers.
When we look in the Exchange queue viewer we always see an error “4.2.1 Service temporarily unavailable”.
We have checked the IP-addresses on http://ipremoval.sms.symantec.com/lookup/ but they’re not listed. We also checked on mxtoolbox.com.
How can we solve this problem ?
IP-address customer 1 : 84.199.77.2
IP-address customer 2 : 81.82.255.131
