Did you mean to exclude SSLv2 and forget the "!"?
You might consider something saner these days:

    DEFAULT:!SSLv2:!EXPORT:!LOW:!kECDH:!kDH:!3DES:!MD5:!SEED:!IDEA:@STRENGTH


In sufficiently recent versions of OpenSSL, some of the above exclusions
are already part of "DEFAULT" (which is "ALL:!aNULL", and, by the way,
"ALL" already excludes "eNULL" which is what "COMPLEMENTOFALL" consists of).
