email errors on CF5

[MartinThorpe]

Hello.

We are using CF5 to run a scheduled task that sends out emails. There are only 100 or so emails being sent but I am getting this error in the log:

An unknown exception happened while attempting to process spooled mail. Polling will continue

I have looked at this tech note:
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_18884

and removed all undelivered files and there are no files in the spool directory, but, this does not change a thing.
Has anyone experienced this and fixed it?

thanks for reading
cheers
Martin

can you dump the mail server logs in here?

Thanks for reading, here is an excerpt from the log, it is all the same so I did not bother to put any more in. There is a tech note related to this error but following that advice I go no-where

OK - I'm guessing you've probably tried this but here goes:

1. Build a CFMAIL page and send an email to yourself. This will confirm the mail server is ok.

2. There is a limit to what can be sent in the To: field of a CFMAIL tag. If the limit is reached the rest is truncated. Hopefully you're looping through the recipients rather than placing them all in the To: field??
<CFLOOP LIST="#theEmailList#" DELIMITERS=";" INDEX="e">
<CFMAIL TO="#e#" FROM="me@somewhere.co.uk" SUBJECT="#theSubject#">
Hi,
#theMessage#

Thanks
</CFMAIL>
</CFLOOP>

3. Check the mail server settings. Can you dump them in here?

Then we can try some more..
