If after making sure that the settings for Local domains and host name in Mercury core and MercuryE configuration are OK (have a look in Mercury help!) sending still fails the most common reason is that your Internet provider blocks port 25. Many Internet providers do this to stop spam bots, unless it's a business connection that is expected to host servers. If so you could try asking them to open port 25 for you, or you could switch to using the MercuryC module and relay mail through your Internet provider's SMTP server.
