Hi Richard

I have been working at trying to get cyrus to listen on 148.197.29.5 
interface instead of the localhost - I have failed

Whenever I add things to /etc/cyrus.conf such as
imaps		cmd="imapd -s" listen="[148.197.29.5]:imaps" prefork=1

[root at maui:~]$ service cyrus-imapd restart

[root at maui:~]$ ps -ef|grep cyr
cyrus    22187     1  0 13:26 ?        00:00:00 idled
cyrus    28044     1  0 13:54 ?        00:00:00 
/usr/lib/cyrus-imapd/cyrus-master -d
cyrus    28048     1  0 13:54 ?        00:00:00 idled
cyrus    28050 28044  0 13:54 ?        00:00:00 imapd
cyrus    28051 28044  0 13:54 ?        00:00:00 pop3d
cyrus    28052 28044  0 13:54 ?        00:00:00 pop3d -s
cyrus    28053 28044  0 13:54 ?        00:00:00 lmtpd -a
cyrus    28054 28044  0 13:54 ?        00:00:00 imapd
cyrus    28055 28044  0 13:54 ?        00:00:00 pop3d
cyrus    28058 28044  0 13:54 ?        00:00:00 imapd
cyrus    28059 28044  0 13:54 ?        00:00:00 imapd
cyrus    28060 28044  0 13:54 ?        00:00:00 imapd
cyrus    28061 28044  1 13:54 ?        00:00:00 pop3d
root     28063 11348  0 13:54 pts/2    00:00:00 grep cyr

Then no "imapd -s" appears

I have tried all sorts of combinations in cyrus.conf but all fail
to LISTEN on 148.197.29.5

I have tried taking maui out of /etc/hosts

My IP addresses are a bit odd - but I have been using 148.197.29.0/24 for 
so long, ...
They have never escaped as far as I know!
client machine
ja at paxos ~ 1$ host 148.197.29.5
5.29.197.148.in-addr.arpa domain name pointer maui.jaa.org.uk.
ja at paxos ~ 2$ host maui
maui.jaa.org.uk has address 148.197.29.5

server machine
[root at maui:/etc/pki/cyrus-imapd]$ host maui
maui.jaa.org.uk has address 148.197.29.5

With these lines in cyrus.conf
   imap		cmd="imapd" listen="imap" prefork=5

   pop3s		cmd="pop3d -s" listen="pop3s" prefork=1
   sieve		cmd="timsieved" listen="sieve" prefork=0

your two netstat lines show

Why will cyrus not listen on 148.197.29.5 ?
