dovecot - Jan 2023 - doveadm proxy list has strange entries

Hi!

I am using dovecot from the latest docker image: Version 2:2.3.20-3+debian11

When getting the proxy list I get the following entries.

# doveadm -f flow proxy list
username=user at example.com proto=imap src ip=10.254.0.13 dest 
ip=172.23.6.194 port=143
username=username proto=service src ip=src-ip dest ip=dest-ip port=dest-port
username=user2 at example.com proto=imap src ip=10.254.0.13 dest 
ip=172.23.6.194 port=143
username=username proto=service src ip=src-ip dest ip=dest-ip port=dest-port
username=user3 at example.com proto=imap src ip=10.254.0.13 dest 
ip=172.23.6.194 port=143
username=username proto=service src ip=src-ip dest ip=dest-ip port=dest-port
...

These correspond to the http API's response:

# curl -H "Authorization: X-Dovecot-API $(echo -n MY_API_KEY|base64 
-w0)" http://localhost:8080/doveadm/v1 -H "Content-Type: 
application/json" -d
'[["proxyList",{},"tag1"]]' | jq

[
   [
     "doveadmResponse",
     [
       {
         "username": "user at example.com",
         "service": "imap",
         "src-ip": "10.254.0.13",
         "dest-ip": "172.23.6.194",
         "dest-port": "143"
       },
       {
         "username": "username",
         "service": "service",
         "src-ip": "src-ip",
         "dest-ip": "dest-ip",
         "dest-port": "dest-port"
       },
...
     ],
     "tag1"
   ]
]


This does not look right.

The proxy list shows the header line from multiple login processes, which ends
up looking like that. This is an old bug. It's finally fixed in the upcoming
v2.4 (because it works completely differently).
