Exchange Server mail flow troubleshooting

I am a new Exchange Server 2010 administrator and just got a job in a medium/large company as an exchange server 2010 admin. I am often asked by my end users about Incoming (Sometime outgoing) email Non-delivery (Internet or even Internal) non-delivery or delay issues.

To give a bit more information, we are using an Exchange server 2010 enterprise server and we install the CAS/HT, mailbox or separate servers. We use a third party spam/content filtering gateway (Tumbleweed), so all incoming mail has to go thru this gateway before entering our exchange 2010 infrastructure. Quite often my end user complain they cannot receive or delay receive email coming from internet and sometimes even within the same exchange site/database server.  I can see from the tumbleweed spam/virus/content filtering console that the email(s) are indeed route to the exchange infrastructure (i.e. the hub role server).

I am quite new to Exchange 2010 admin, may I know what is the best approach or steps to troubleshoot or track down the issue or the root cause of the message undeliverable or delay ? I see there is quite numbers of tools (e.g. Message Tracking, mail flow analyzer etc.) but don't know a systematic way or steps. Can anyone with more experience as far as Exchange 2010 troubleshooting is concerned give me some hints or guidelines ?

Thank you so much for your kind assistant in advance.

the initial diagnosis is pretty much the same process as any version of Exchange.
Start by identifying where the delay is, probably by monitoring the flow of test/example messages through the tracking logs and checking for errors in logs.

Once you know where the delay is you can look at resolving it.
