I've tried the changes that I put below. Users are still able to log in from the LAN.
However, despite putting the appropriate rule in my firewall allowing port 143 I cannot create a user on a PC outside my network.
I'm using Thunderbird to do the testing. Is there a better way to test my setup? Thunderbird doesn't give any diagnostic data, it just says it's failed to test the account.

I have a mail server running on Centos 7.2 which has been working for my LAN for a long time.
I'm at the point where I have to make it accessible to the internet. At the moment, access can be insecure but as it's on my LAN it isn't an issue.
However, for internet access I wish to force SSL/TLS. Having read the documents I think it's as simple as changing 10-ssl.conf from
ssl = yes
to
ssl = required remote 10.0.0.0/8 { ssl = yes }
Am I right in thinking that this would make the global value now force SSL/TLS to be required, but for my LAN (10.0.0.0/8) override this with the old value of 'yes'
Is there a better way to do this? Have I missed anything? I believe that this means implies
disable_plaintext_auth = no
for all except my LAN. Is that right? _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
