fetchmail error with ssl

[Alexander Marx]

Dear List,

i installed a new Kolab 2.2.2 and now i added the fetchmail rpm from
openpkg.
when i try to get mails from the server pop.1und1.de i get following errors:

fetchmail: Server CommonName mismatch: pop.1und1.de != 212.227.15.178
fetchmail: Server certificate verification error: unable to get local
issuer certificate
fetchmail: Server certificate verification error: certificate not trusted
fetchmail: Server certificate verification error: unable to verify the
first certificate

This error is discussed in plenty of sites. the best solution for UBUNTU
would be to just install ca-certificates via apt-get.
that does not solve the prob, as it is a openpkg rpm.

What can be done to get rid of this errors?

is there a openpkg package wich includes all of the ca certificates?

1und1.de seems to use a certificate from thawte.

i want to put this mailserver in production so i would be glad for a
quick and helpful reply.

By the way: my old Kolab 2.0.3 does  work with an fetchmail  without
errors, but that installation is 3 years old....

Thanks in advance,
--
