Only that you mentioned an 'encrypted mail', which is not relevant to
your problem.

It could be that the server rejects your use of 'localhost' (EHLO
localhost). If you don't want to change this in your system, then
just do it in Claws. Go to the Account preferences, Advanced page,
and set something for 'Domain name' -  anything other then the
generic 'localhost'. (It can just be a single word, doesn't need to
be an FQDN).

If that still doesn't help, then study again comment no. 5 in the bug
tracker item, where you were provided with working settings.
