Hi,

I am trying to setup a dovecot server on my laptop to serve my emails to emacs gnus. The emails are pulled from the mail server using isync into particular directories. I am using a Guix system.

The dovecot service is running. I can telnet into it with:

telnet localhost 143

Trying 127.0.0.1... Connected to localhost. Escape character is '^]'.

• OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ STARTTLS AUTH=PLAIN] Dovecot ready.

However if I then do:

b select inbox

b BAD Error in IMAP command received by server

I have not logged in as I have not set any username or password. I assumed that access was open on localhost. Is this not correct ?

I am not sure how to check further. I have checked the configuration and it is pointing to my email directories, imap is enabled etc.

Thanks

Roy.

Hi!

You can use ANONYMOUS mechanism if you want to allow public access. Clients might get confused with no authentication at all.

But even then you need some user to access as

See https://doc.dovecot.org/configuration_manual/authentication/authentication_m...

and

https://doc.dovecot.org/settings/core/#auth-anonymous-username

And here is simple config based on what we use to expose mailman archives. It should work, but as I removed settings there is small risk of mistake.

You need /srv/dovecot/anonymous directory with mail, control and index directories. control and index need to be writable for vmail.

Then we symlink /var/lib/mailman/archives/private/dovecot.mbox/dovecot.mbox as /srv/dovecot/anonymous/mail/dovecot

dovecot.mbox should not be, as this is read-only archive.

## dovecot.conf auth_mechanisms = anonymous # index and control need to be writable mail_home = /srv/dovecot/%Ln mail_location = mbox:%h/mail:INDEX=%h/index:CONTROL=%h/control passdb { args = /etc/dovecot/anon.passwd driver = passwd-file } userdb { args = /etc/dovecot/anon.passwd driver = passwd-file }

## anon.passwd anonymous:{PLAIN}:vmail:vmail::/srv/dovecot/anonymous::nopassword=y
