Sharepoint 'Alert Me' function no longer working

What version of SharePoint?  Are any emails getting out of your farm at all?  This could be an issue with your SMTP configuration or server.

No emails at all.
Windows Server 2008 SP2 x64
Windows SharePoint Services 3.0

THen this isn't an Alerts issue, it's a configuration issue.  What do you have specified for your OUtgoing Email server in Central Admin?  Is it a seperate server?  Is it Exchange?  Do you have relay enabled in Exchange for the SharePoint server?

The same server also has exchange installed. Outgoing email server has its IP address.
There is also an internal relay setup for the subnet.

Can you specify a server address rather than the IP in the outgoing email?

Tried the full internal DNS name on port 25 and it didn't work
I also tried an external URL on port 25 and it also didn't work.

go to exchange system manager > your server > properties > diagnostic logging > MSexchangeTransport > increase the level of logging to maximum for NDR, SMTP protocal ,,all on this category.
try again and check the application log viewer (post the error/NDR)

is only alerting affected? what about site access requests?

i would suggest also to check WSS logs for any smtp error. hope this helps. andrea-

Its Exchange 2007 SP1, so those options might be command line based.
What service logging level am I switching?

MSExchangeTransport\SmtpReceive  at least.


or using the registry

is the domain name used on the wss sender (i.e. sharepoint@blabla.com) a valid smtp domain in the exchange organization? is the domain the same used on your mail users?
have you tried to change the wss sender address with the same domain name?
just excluding relay issues

Ok increased logging level on MSExchangeTransport\SmtpReceive.

The wss sender is using the administrator email address for the domain.

ok. pls try testing wss alert or access request. if exchange has problems you may find the error logged on the windows application log viewer.

Error:
SMTP rejected a (P1) mail from 'administrator@xxxx.org' with 'xxxx' connector. The user 'anonymous' does not have permissions to send as this address.

There is an internal relay setup for the subnet, but the error is on the wrong connector.
Anonymous access is only enabled on the other connector.

I don;t know why our existing email relay connector with Anonymous access doesn't work. But your link helped me setup a new one.

Thank you.
