I have a quite old home server based on Debian 6.x packages using courier imap server (exim4, fetchmail, courier, apache2, squirrelmail) to keep my and my wife emails (about 25G). I want renew my server to Debian 10 (buster) and got a recommendation to use dovecot instead of courier. For this purpose I'm using a different PC as a sandbox. Debian 10 currently offer dovecot version 2.3.4.1 Installation was "peaceful" but stuck with the migration. I have choose migration using dsync, from Wiki I was choose this command: For per-user user/passwords use: doveadm -o imapc_user=foo -o pop3c_user=foo -o imapc_password=bar -o pop3c_password=bar backup -R -u user@domain imapc: (foo and bar placed real username and password) But I get error: doveadm(tovis(a)nusi.tovis-lab.mydomain.org): Error: User doesn't exist Strongly I have no real domain, I'm using "freedns". "nusi" is the local name of my old server, "tovis-lab" is conjunction with "mydomain.org" choose from freedns. I was trying short as "nusi" which is in /etc/hosts file even ip address but the same result. 143 and 943 ports are working only inside the firewall (OpenWrt). I was checked using telnet courier on the "remote" box and dovecot on the localhost. I was able to login. What should I use as "user@domain" in this situation? tovis
