Yesterday I set up iRedMail on AWS. It was working, then I changed nothing and now connections to it are timing out. I can still connect to the AWS instance on putty, but trying to connect to iRedMail services via webmail or Thunderbird just times out. I enabled all debug logging options and looked into all of the log files, but it's not displaying connection attempts or errors anywhere. It looks like all the services are running correctly.

What I think happened was that earlier I was changing hostname settings in various files in order to have the proper HELO displayed (so that my outgoing emails are not classified as spam). Everything was working, but maybe some of the settings I changed only took effect after a reboot and then broke something. I tried to revert my changes and I've tried various hostname settings, but so far no luck.

I don't know if it's just easier to wipe it and start from scratch.
