PIWIK isn’t sending automated emails anymore (we had recently swapped servers). Here is some more information:
[li] ‘Forgot Password’ email is being sent
[/li][li] ‘Send report now’ email is being sent
[li] We are using PIWIK 2.0.3
If no one replies, we may just upgrade PIWIK to 2.2.0 and see if that fixes the issue.
