Hi,
we started 13th of may 2017 using a new subnet for our servers. Since then we are unable to send email to some destination because of your blacklist :
host smtp.aliceposta.it[82.57.200.133] said:550 mail not accepted from blacklisted IP address [92.222.116.148] (in reply to MAIL FROM command)
last week i had to request the delisting every two days, and yesterday I setup relayhosts in postfix to route everything to old VPSes ( luckily still working at the moment ).
My IP range is 92.222.116.144 to 92.222.116.151, can someone of the Symantec take care of this and help me not to fall again in blacklist?
I think that if all emails , without arising alarms, pass through old VPS IP's they should pass from new IPs too...in fact we just moved VPSes to new IPs just reconfiguring their interface address
1) Symantec is the only to blacklist our mail servers.
2) There's no spam coming out from our mail servers
3) There's no virus on our mail servers
4) Our mail servers are not open relays
5) Our mail servers has not dynamic IPs
6) Our inverse records are correcly registered for the name of the new server
7) Our SPF records are present and working for the main domain
Please help, i can't maintain old VPSes working more than a week ...
best regards
Stefano Gatto
