Thanks, yes, that solved the problem.
I"ve been out of office for some days now, so I just could try it now, but with proto=tcp it seems to work fine. cyrusmaster binds to both ipv6 and ipv4 stack. Just one more question: why not handle ipv4 also via ipv6 stack (via 6to4 adresses) like most other software does?

Thanks,
