HELP! - weather report e-mail does not work anymore :(

I didnt change something - since today no weather report email did arrive, though wd dials up and looks normal. ftp error log looks also OK.

2 day ago this problem started always with one waether report email at the same time which did not arrive. I tried adding another time and this one also didnt work. So I removed all times for sending and set these times once more. And now no one of the weather report mails works :((((
what could be the reason - has anbody an idea?
I am using vers 9.84e.

please help! thx very much!
