postfix lmtp permission problems

Have to set up an email server.
Installed Postfix with Cyrus IMAP.
After configuration I ran a test email ( echo mail | mail -s test larcher )
I got the following messages in the maillog:
Oct 16 08:56:45 redriver01.ids4zos.net postfix/qmgr[862]: C518FBB7B: from=root@ids4zos.net, size=433, nrcpt=1 (queue active)
Oct 16 08:56:45 redriver01.ids4zos.net postfix/lmtp[2677]: C518FBB7B: to=larcher@ids4zos.net, orig_to=, relay=none, delay=504, delays=504/0.01/0.01/0, dsn=4.4.1, status=deferred (connect to redriver01.ids4zos.net[/var/lib/imap/socket/lmtp]: Permission denied)

While /var/lib have the owner and group as root
imap/socket/lmtp directories have cyrus as the owner and mail as the group.

drwxr-xr-x. 2 cyrus mail 6 Oct 15 11:08 lmtp

from the id command
[root@redriver01 /]# id mail
uid=8(mail) gid=12(mail) groups=12(mail)
[root@redriver01 /]# id cyrus
uid=76(cyrus) gid=12(mail) groups=12(mail),76(saslauth)
[root@redriver01 /]# id postfix
uid=89(postfix) gid=89(postfix) groups=89(postfix),12(mail)

I tried chroot for lmtp in the postfix master.cf file, however that didn't work because then it could not find the /var/lib/imap/sockets/lmtp directory structure.
Any ideas and/or suggestions would be most appreciated

Cheers

Guy
