Strange behaviour

[Eduardo Rocha Costa <eduardorochacosta@ieg.com.br>]

Hi, all I really have a strange problem, 
I configured exim (I think) to receive e-mails 
the procmail and fetchmail to
well then, when I do

$fetchmail -k
I receive all e-mails from the pop server and all correctly 
but when I do

$fetchmail 

I receive all e-mails but one or two line in each
Really strange huh ?

And one more related question,
my smtp servers needs authentication to send e-mails 
but I can't configure exim or mutt to do this
anyone has a hint a FAQ or anything to help me ?

Thanks

Eduardo
