Some users reported that they just received an email sent on 30 March 2009.
Which is "late" for one year!

How to tackle this kind of issue?

Sounds like someone rebooted a mail server somewhere. Look at the
Internet headers on one such message to see where it was held up -
MXToolbox has a nice utility for this: http://www.mxtoolbox.com/EmailHeaders.aspx
