I have been setting this up and all worked well until I got to the Tests - sa-learn section where I get errors when executing these command line checks.

su -s /bin/bash - amavis -c "spamassassin -D bayes < /opt/sample.eml"

and 

su -s /bin/bash amavis -c "sa-learn --dump magic"

bayes: cannot open bayes databases /var/lib/amavis/.spamassassin/bayes_* R/O: tie failed: Permission denied
ERROR: Bayes dump returned an error, please re-run with -D for more information

The error messages are using root user.  All is well elsewhere and the services are running. TIA.

Re: Auto learn spam/ham with Dovecot imap_sieve plugin

Try to switch to "amavis" user first, then run the commands (without the "su ..." part):

su - -s /bin/bash amavis
spamassassin -D bayes < /opt/sample.eml

Thank you.  Still have a problem.

su - -s /bin/bash amavis
Password: 'Database password'
su: Authentication failure

What is the password for amavis?  I cannot authenticate.

Re: Auto learn spam/ham with Dovecot imap_sieve plugin

How about "su -s /bin/bash amavis" (without "-" after "su")?

Thanks, this - was a typo, I did not use it in the terminal.

Check detailed bayes learning log wrote:
# su -s /bin/bash - amavis -c "spamassassin -D bayes < /opt/sample1.eml"
-su: /opt/sample1.eml: Permission denied

Still have the problem. As this one also.

Re: Auto learn spam/ham with Dovecot imap_sieve plugin

Both commands works fine for me on a Ubuntu 18.04 VM.
What's the owner/group/permission of files under /var/lib/amavis/? Check them one by one.
