I've configured my ASA5505 to allow SMTP out from and into the network. However, when I do a telnet test on port 25 to my relay server, it fails with the following (log traces):

I know that this relay server is accessible from other networks with ASAs at the edge. Is there a config error somewhere?
BTW, incoming SMTP works totally fine.
