So - Had a few hours to kill, so I thought I would spend some time installing a brand new iredmail-server, and later migrate. I did not finish, but will look at it again later. But my observations so far.

1. Grabing the tar-ball onto a fresh FreeBSD install would give an issue with unknown certificates from download-site.
/usr/ports/ca_root_nss would most likely fix this. But I just pulled the tarball adding '--no-verify-peer' to the fetch command.

2. Dovecot version1 is removed from ports, and dovecot2 is now just dovecot.
I just made a temp. symlink, in 'usr/ports/mail' so that dovecot2 becomes dovecot.

3. ClamAV portinstall fails.

I have no clue as to why this fails.   '/usr/ports/security/clamav/work/clamav-0.99.2/unit_tests/test-suite.log' contains this:

I will check with the ports-maintainer, but this looks like a new bug.
