Thanks (多谢) for making iRedMail available.  At this time, I don't have any questions, but maybe these comments will be useful.

Bug: spamassasin configuration by iRedMail.sh fails because gpg-agent is missing. It seems to work when re-running iRedMail.sh again, but I doubt it because gpg-agent still is not installed after running iRedMail.sh the second time.

Workaround: Install gpg-agent before running iRedMail.sh.  I also install apt-utils before installing gpg-agent to avoid a warning.

Bug: chown syslog:adm fails (many times) during the run of iRedMail.sh because user syslog does not exist.

Workaround: create user syslog (groups adm and tty) before running iRedMail.sh

Bug: iRedMail.sh marks everything DONE and reports it ran without problems in spite of the chown errors.

Workaround: does not matter if user syslog is created before running iRedMail.sh

Bug: HSTS is implemented, so I cannot use the admin panel with the self-signed certificate even if I am willing to grant an exception.

Workaround: Install a valid certificate before tyring to run the panel

Bug: The forum has a short timeout so you are likely to lose everything you are composing in your topic post.

Workaround: Compose your post in a separate editor and copy it over.

I'm sorry I can't show the logs.  I saved the output from iRedMail.sh from the terminal to a file, but the file was wiped out when I re-imaged the server again to try out the workarounds. d:
