SMTP server problem because of too short keys

Starting a month ago, mail programs could get an update due to the vulnerability for a LogJam attack. After this update these programs refused connections with a server with a too short key. The old C&CZ authenticated SMTP server had such a short key. Users who reported this problem (with the latest versions of Pine, Thunderbird and recently also Apple Mail), were advised to temporarily use an alternative server. As of today using this alternative server is no longer necessary, because the server smtp.science.ru.nl has been replaced by a new server.
