I've just found that the default exim4 configuration (exim4 4.20-1 deb
package) comes with no smtp_accept_queue_per_connection value.
So exim4 default, which is 10, is taken as a value. So if you have a
dialup connection, and fectchmail retrieves more that 10 messages in one
smtp connection, then exim4 will kindly deliver the first 10 messages,
and the store the rest of them in /var/spool/exim4/input/
To deliver this "lost" messages, use exim4 -ql
So you should set smtp_accept_queue_per_connection to a higher value if
you are in this case (I use 1000). I did put this in
The risk, as ...
