Sendmail dyn IP
If port blocked your server will return error connection timed out with server. Because edpnet blocks all traffic via port 25 (On Dynamic IP) except to our relay server.
So you need to set up our relay as smtp server , how to do it :
- go to sendmail configuration :
- and set up relay.edpnet.be as smarthost :
- MASQUERADE_AS(`you FQDN')
