Kresolve host -a<OKR> -T<TEMP>

Kaccess cdb -T<TMPF> /etc/mail/access
root@deb-test:~# 

The file access seems to work, I checked with auditd and also added
entries (without colons) that worked.

So I assumed that the following works, but the stuff with the colons
does not seem to work:

root@deb-test:~# sendmail -bt 
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> /map access Connect:IPv6:::1
map_lookup: access (Connect:IPv6:::1) no match (0)
> /map access reject@
map_lookup: access (reject@) returns REJECT (0)
> /map access Connect:192.0.2
map_lookup: access (Connect:192.0.2) no match (0)

On other Debian systems with db5.3, such lookups work.

What are I am doing wrong here?
