New FREAK SSL Attack CVE-2015-0204

[Adrian Minta]

Hello,
about the CVE-2015-0204, in apache the following config seems to disable 
this vulnerability:
 SSLProtocol All -SSLv2 -SSLv3
 SSLCipherSuite 
HIGH:MEDIUM:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4

Is something similar possible with dovecot ?
If yes, what are the implications with old mail clients ?
