Since the localhost4 approach worked, commend out the ipv6
localhost entries in your /etc/hosts file, then try:
IP6 is commented out
dig @localhost localhost a
That works
again. If that works try:
telnet localhost 143
This also works
once again. If those work, it would seem that your ipv6 is messed
up and your system is trying it first and not falling back to ipv4.
Regarding your nameserver list in /etc/resolv.conf. If you have a
working 127.0.0.1 nameserver you generally don't include external
nameservers in that list. So, if non-ipv6 things seem to work, I'd
remove the two non-127 nameservers from that list.
Removed the two nameservers. Still can't access mail. Getting
connection to storage server failed on the roundcube login page.
That you can now successfully get to "localhost" is good progress.
Seems you want to stay away from ipv6 networking issues unless/until
you resolve whatever that issue is.
Roundcube is, potentially, a totally separate issue. I don't use it,
so can only suggest minimal debugging ideas.
What is the hostname that you use to get to your roundcube instance?
Can you resolve that:
dig <hostname> a
If you get an answer, is the ipnumber correct?

Note, if the hostname for your roundcube instance is one of the ipv6
entries in your /etc/hosts file, I'd remove that - and either put in
an ipv4 entry or put an entry for it in your dns.
Thanks again! I still think it's a mail issue. I can't get mail using
usermin either.
Think I'm going to remove the TLS stuff from postfix main.cf that I added
yesterday and retry.
If I missed this further up thread my apologies - is SELinux enabled and
are there any relevant exceptions being logged?
