I don't know in which ebuild this bug is located, but in my '/etc/services' there is:
cisco-sccp 2000/tcp # Cisco SCCP
sieve 2000/tcp # Cyrus SIEVE
and w/o the 'sieve' entry, sieve daemon could not be started within cyrus-imapd. But it worked some time ago!
Steps to Reproduce:
IANA has allocated port 2000 to 'cisco-sccp'
file a bug with IANA :P
don't close Bugs before asking!
it may be a general problem. But then there should be an 'einfo' about this fact in the cyrus-imapd ebuild.
i asked myself and we agreed that the bug should be closed ... talk a chill pill :P
i forgot we can do aliases in services so ive changed it to read:
cisco-sccp 2000/tcp sieve # Cisco SCCP
cisco-sccp 2000/udp sieve
thanks. perfect solution!
