I upgraded from v0.29 to v0.30 and then installed a new machine with same IP and installed v0.40. I did a restore of backup and everything seemed to be working as far as emails are concerned.
Today I noticed that my Custom DNS is not working correctly when every I try to ping A records they do not resolve locally.
When I run ‘sudo mailinabox’ I immediately get ‘sudo: unable to resolve host mail’.
When I try to delete and recreate custom dns entries I get the following error.
Custom DNS (Error)
