        Hi @ckruijntjens ,

        I just updated to the latest master (which is 8.6.80.743-84.1 at the time of writing) and cannot reproduce the described issue. For me the dagent is starting fine and I can deliver mails via lmtp.

        Regards Felix

            Ah, that’s an error someone can work with.

            There must be another process already listening on port 2003 (which can simply be an old binary). I’d suggest to kill the old process manually and then start the dagent via systemd.

                  Sorry this is No question. It works if I change it to port 2004. If I then look What is using port 2003 it is kopano-dagent ipv6?

                  If I change the port to 2003 in dagent.cfg the it starts to complain again?

                      Im sure this is a bug.

                        and the fix is pretty simple.
                        i changed lmtp_port = 2003 to
                        lmtp_port = 0.0.0.0:2003

                        results in :

                        Fri May  4 11:49:18 2018: [=======] [13391] Starting kopano-dagent version 8.6.80 (pid 13391) (LMTP mode)
                        

                        Now only this is NOT correct, so its still buggy imo.

                        netstat -plant | grep kopano-dagent
                        tcp6       0      0 :::2003                 :::*                    LISTEN      13391/kopano-dagent
                        

                        I’ve set 0.0.0.0:2003 why is the listen on ipv6 ?

                          Please post your dagent.cfg - your problem might be related to an issue with option lmtp_listen.

                            In dagent.conf, If you set

                            server_bind = 0.0.0.0
                            lmtp_port = 2003

                            and what is “server_bind_intf”
                            What do you need to set here, totaly unclear with the current text in the config.
                            Sorry but server_bind_intf is a joke, remove it, where is this for? limit to ipv4/ipv6.
                            above settings like
                            server_bind = 0.0.0.0 should set all adresses. ( ipv4 and ipv6 )
                            server_bind = [::1] should set only ipv6 localhost adresses.
                            server_bind = 127.0.0.1 should set only ipv4 localhost adresses.

                            I cant think of any use for server_bind_intf, is only more confusing imo.

                            so yes, imo, a bug.

                            forgot to mention:
                            dpkg -l | grep kopano-dagent

                            i’ll go test the daily update now.

                                Hello,
                                there have been recent changes to dagent interface/port configuration to match server.cfg nomenclatura.
                                server_bind,server_bind_intf,lmtp_port will be declared “legacy”

                                try:

                                lmtp_listen = [::1]:2003 127.0.0.1:2003
                                lmtp_port = ""
                                

                                to listen on IPV4/6 localhost addresses.

                                There’s an issue with option lmtp_port - read here - already fixed, but probably not contained in current community builds, yet.

                                ++umgfoin.
