Trouble Shooting CUSTOM SMTP

Updated on Follow
0 out of 0 found this helpful

 

At times, Custom SMTP may not work properly if the client's network/servers are blocking traffic to unknown IP addresses. To allow Custom SMTP to work for clients whose networks have this security in place, their Network Administrator will have to specifically allow traffic from our Custom SMTP servers. This procedure is called "whitelisting" and it means that they've made their network/servers aware of and allow traffic from specific IP addresses. Below are the IP addresses they'll need to whitelist to allow Custom SMTP to work.

198.101.135.153
198.101.135.154
198.101.135.155
23.253.1.248
162.209.47.173

 

Make sure you write down which clients you provide these IP addresses for. In the event that we make changes or additions, we will need to notify those clients!
