Mail Fetching doesn't work

Hi,

I have a problem with incoming mail fetching. Mailbox informations are correct, and the connection test did while saving settings is ok.

But emails aren't fetched, and "Last attempt to fetching mail" contains an empty value.

More, in scheduled list windows there is this row:

More, when I try to stop and restart mail fetching following rows appear in the log file:
