Issue with List

[Rod Rayner]

Hi,
We seem to have an issue with a single list on a customers account. The list is around 7000 recipients and when ever they run a campaign using this list the campaign stalls after sending x number of emails. We have exported the list, checked it in excel and re imported it under a new name, run a campaign against the new list but the issue has not gone away.

Is there any way to find out where the list is causing an issue, i expect it must be a bad email address or something.

Thanks

Hi,
enable debugging in send campaign and check the log

@Rod Rayner - Check if you have some errors in backend - misc - application log

All sorted, ran a campaign in debug mode and found the error. Basically the SMTP server was taken overly long to communicate and the SQL server was timing out. Changed delivery servers and the problem went away and have also increased the SQL Timeout from 10 seconds ( i think is default ) to 60 just in case.
