dovecot - Mar 2023 - Can't seem to setup remote access to doveadmI'm using

I?m running version 2.1.7 under Raspbian Wheezy (and have been for a number of
years). I want to allow one of my other computers to remotely issue doveadm
commands to my server but can?t seem to find the right way to add an inet
listener to permit this.

Using ?doveconf -a? I?ve found the default service definition for
doveadm-server. So I copied that and added it to the dovecot configuration with
an inet listener section added to it. But that was rejected as a duplicate
service definition when I restarted dovecot. I then tried specifying a
?host:port? value for the doveadm_socket_path value but that didn?t work as no
listening socket at that port appeared when I restarted dovecot.

I can?t seem to find in any of the dovecot documentation a way to do this and
there seems to be nothing like a ?Here?s how to setup doveadm remote access?
section in the documentation (which would be most helpful).

How can I get doveadm-server to listen not only locally (as it?s already doing)
but also open an inet port for remote access?

ok there might be other ways to do this but here is what i did for my 
django project

I had to create a listener in python

PLEASE PLEASE PLEASE BE CAREFUL !

This script is designed to work on a closed network and is still rough 
around the edges but does work

needs to be run as root in the background to access the doveadm.

If you intend to access from outside then you need to secure it by 
static ip, username/password etc ???

The client side code sends an email to notify you when the script is 
accessed?

Can help if you get stuck.

and then in django / or outside ? :

_______________________________________________________________________

     #Try to get info for this account
     if dontupdate == False :

       imap_test = Dovecot_Command ('INFO',self.username) #do i have 
this account ?

       if 'BAD' in imap_test.answer :
         try : #Try to Create the account, note that the db must be 
updated properly before it will work
           imap_create = Dovecot_Command ('CM',self.username)
           if 'OK' in imap_create.answer :
             send_subject = 'Email Account Created : %s' 
%(str(self.username) )

         except :
           send_subject = 'Error Account : %s' %(str(self.username) )
           pass

       else :
         send_subject = 'Email Account Updated : %s' %(self.username)

       #Send update email

       send_from = 'monitor at scom.ca'
       send_files = []
       send_to = ['monitor at scom.ca']
       send_text = '\n\n'+ send_subject + '\n'
