The IPs line format is wrong! [127.0.0.0/8,192.168.0.13/32,::1,2888:bb:30:300:2222:3fff:eeee:ca8d]

How to Fix?
Settings > Zimbra Admin > Servers > MTA Trust Networks field. In the property format, loopback IPV4 and IPV6 must be included!

IPV4/mask IPV6/mask

127.0.0.0/8 192.168.0.13/32 ::1/128 2888:bb:30:300:2222:3fff:eeee:ca8d/64
