Hi
Assuming that you're using exchange you can trace the mails sent and
received through message traking center under tools (in exchange manager).

First thing to do is check if your exchange is resolving correctly the MX
records.
- Nslookup <press enter>
- Server ipserver <press enter>
- Set Type=MX <press enter>
- domain.tld <press enter>

if everything ok, start the SMTP test is some tools tha you can use
Email/SMTP Test Utility

*if you're using ISA with mail relay check this link :Configuring an Inbound
and Outbound SMTP Relay to Complement ISA 2004 Firewall Protection for
Exchange Servers
