the problem I had:
"Fetchmail has problems too, by resolving mails - it slowes down after popping some mailboxes - and then it needs a long time to manage the rest. - reindexing does not help "
now is fixed!!!
You need to turn the IPV6 realy off, there is an balancing between IPV4 und IPV6 during the whole time, but aktually I don't need the IPV6.
to check the performance you can check fetchmail manualy by typing:
fetchmail -v -f /"your path to Fetchmailcatchconfig file [maybe /etc/fetchmailrc]"
since I did that, the Fetchmail needs only some seconds to check over 70 mailboxes.
Solution to turn IPV6 off:
for Suse Linux
changes in /etc/modprobe.conf
alias net-pf-10 ipv6
into:
alias net-pf-10 off
alias ipv6 off
then reboot the server
have a nice day..
