Mail Notifications Stop Working

We have some jobs that should e-mail the operator upon certain conditions.
For reasons I cannot seem to find, the e-mail notifications have stopped com
ing (net sends do work). I can send mail from the SQL Agent service account
from the desktop, but SQL
won't even send me a test mail from within SQL (using Ent. Mgr). However, S
QL thinks the mail was sent OK, as it says "mail successfully sent". Howeve
r, the test mails never show up. Short of rebooting the server (a 24/7 prod
uction server), I don't kno
w where to go. Have checked the accounts, stopped and started the agent, et
c. If this is a clue, the agent also won't run some scheduled jobs. One da
ily job actually last ran two days ago, yet I don't see any errors or messag
es. Using Win2K, SQL2K (SP
3a) on a 4-processor Dell box.Do you have any warnings or errors in your SQL Server Agent
Error log - right click on SQL Server Agent in Enterprise
Manager and select Display Error Log.
Also - are you by any chance running in fiber mode?

nformational ones that are found when restarting the agent, i.e., version, p
rocessors, memory, etc. It says the mail session was successfuly started.

SQL thinks the mail was sent OK, as it says "mail successfully sent". How
ever, the test mails never show up. Short of rebooting the server (a 24/7 p
roduction server), I don't
know where to go. Have checked the accounts, stopped and started the agent,
etc. If this is a clue, the agent also won't run some scheduled jobs. One
daily job actually last ran two days ago, yet I don't see any errors or mes
sages. Using Win2K, SQL2K
