dovecot & cap_net_admin capability

[Michal Hlavinka]

>> we've seen SELinux reports from our users that dovecot tried to use something that needs CAP_NET_ADMIN capability. Before enabling it, we would like to know where it originated from. I've checked the sources, but was not able to find anything that would require this capability. Do you know for what it is used?

Thanks for the answer. We've looked into this a little bit more and 
found out that this message is caused by what happens in kernel (and 
network configuration). It is not caused by what dovecot does.

Cheers,
