Hello,

When extracting client_id information from the client connection (i.e. setting imap_id_log = *) the information is directly logged by Dovecot as such:
ID sent: name=Thunderbird, version=91.5.0

My question is, Is it possible to export/set this information in a checkpassword script or a postlogin script?

client_id

If imap_id_retain is enabled this variable is populated with the client ID request as IMAP arglist.

I've enabled both checkpassword and postlogin on a test server, as well as 'imap_id_retain' set to 'yes'. I wrote a simple Perl script that dumps everything in %ENV as well as @ARGV for checkpassword and postlogin, but I don't see any occurrences of ID information. I've also tried to see if I could supply that variable in dovecot.conf by setting 'client_id' as a parameter, but that didn't seem to do the trick either.

passdb {

...

   # Doesn't work
   args = /usr/local/bin/checkpassword.pl client_id

   # Doesn't work
   args = /usr/local/bin/checkpassword.pl %{client_id}

...

}

What am I missing? Is it possible to get these variables into an external script that checkpassword or postlogin executes?
