Many thanks to Alexander, Richard, Jonathan and m.roth
The Magic incandation !
portrelease dovecot service cyrus-imapd restart
[root@maui:/etc/named]$ cat /etc/portreserve/dovecot imap imaps pop3 pop3s
My total ignorance of portrelease/portreserve has been a bit of a problem!
Now to fix it permanently and get evolution back in one piece
But why was cyrus able to use imap, pop3 & pop3S but not imaps?
John
Look in /etc/portreserve/ and look at the files there (both the names on the files and their contents). That will give you a sense of what services are covered. Your previous netstat output indicated that portreserve was "holding" both 143 (imap) and 993 (imaps). Since we were focusing on imap I didn't ask for netstat for other ports, so don't know what else it might have been "holding".

What did you configure in your DNS and set in /etc/hosts? Please provide last one.
I am running a DNS server on maui that is updated by DHCP as required The zone file looks like this at the moment IPs between range 148.197.29.129 148.197.29.253 ; are dynamic, the rest are fixed

I'm not certain where that's coming from. That will all work internally (assuming internal consistency), but the outside world has a rather different view.
The information returned by whois for jaa.org.uk (which has your name as registrant) shows:
Name servers: ns.hosteurope.com ns2.hosteurope.com
as the nameservers for that domain.
If you do a "dig" against either of those servers for your maui host:
dig @ns.hosteurope.com maui.jaa.org.uk
you get:
maui.jaa.org.uk. 14400 IN A 213.152.52.233
An rDNS lookup on that IPnumber returns:
233.52.152.213.in-addr.arpa. 56246 IN PTR jaa.org.uk.
while the rDNS on 148.197.29.5 returns:
5.29.197.148.in-addr.arpa. 50161 IN PTR adarwash1.ee.port.ac.uk
which matches the forward lookup:
adarwash1.ee.port.ac.uk. 86400 IN A 148.197.29.5
So, the outside world has a rather different view of what your ipnumber(s) are than you seem to be getting/using internally.
