Huge mail delay (ident callback?)
Posted on 2006-10-24
All the mail we receive comes with a delay, some with a delay of like 2 hours.
Now my isp tells me that this can be changed by setting ident callbacks to timeout in 0 seconds or disabling ident callbacks,well i looked under every rock on the internet and cannot find a solution, anyone ?
We are using Exchange 2003, where we use an external mail relay server of our isp that does not allow ident callbacks.
Port 25 is closed inbound so we have to use their mailrelay server.
