What do these messages in the Qmail maillog indicate?

- by Griffo

There seems to be an endless supply of messages in the Qmail maillog for a single address. Can anyone shed some light on why this might be and whether it is a problem?

How do I allow users to dial numbers in my tableView cells?

- by Griffo

Hi all, I have a table containing cells with phone numbers. How can I allow the user to dial these numbers by tapping the row?
