I don't think that is strictly so. With Pegasus Mail (and I had
thought of doing this once the panic attack had passed)
I can download the headers only from my ISP,
and then at leisure mark them for collection or deletion which it will do when
I reconnect. At leisure means while I am offline, but while the
header screen is still up as it does not save this info for later
use (exit Pegasus and it is lost).

Both yourself and dman suggested that i look in the exim log files.
Why did you not say to look in the fetchmail log file? Apart from
the fact that this would seem the place to look, why did you not
suggest that (that is, why _did_ you suggest the exim log)? What bit
of knowledge am i missing here?

the -e option looks useful
