Cannot login with method=GSSAPI
by Erik Haller 17 Aug '17

17 Aug '17

I am migrating an existing dovecot server to a new server. The existing server uses pam_krb5 and works with the plain and gssapi methods. The new server plain/pam_krb5 normal password authentication works. However, the gssapi (tickets) authentication is producing the following error: === Begin Error ==== imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.7.61, lip=192.168.7.97, TLS, session=<SPnD7NhWWtrAqAc9> === End Error === What is causing the "user=<>"? It should be "user=<erik>". I have been using Thunderbird SSL GSSAPI from a Debian Linux testing/buster XFCE desktop to connect to the existing server for years. When I point it to the new server, I receive the above error. ssh kerberos gssapi authentication is working fine on the new server. Most of the doveconf setting between the existing and new servers are the same. The existing server is 32 bit. The new server is 64 bit running in an LXC container. The existing server dovecot version is the same as the new server. Notes: dovecot version: 2.2.31 (65cde28) OS: Debian Linux testing/buster Arch: amd64 Client: Mozilla Thunderbird 52.2.1 (latest)

Hello, I have a question : if I have multiple servers sharing a single disk space (NFS... cluster), and a message is delivered via say LMTP or LDA to a mailbox, and an IMAP client is in IDLE mode on another server, Will it get notified of the arrival of the new message (and if yes, how ?) Thanks, --Ivan

FTS Lucene Search by Word Parts
by Webert de Souza Lima 16 Aug '17

16 Aug '17

Hello, as the dovecot documentation is only trivial for FTS Search options, I can't find information on advanced options. I have enabled it but it seems I can only search for entire words, i.e. the word Dovecot can be found by searching "dovecot", but not "dove". Is it possible to achieve this using FTS Lucene? I know that using Solr that achievable setting n-gram. Regards, Webert Lima DevOps Engineer at MAV Tecnologia *Belo Horizonte - Brasil*

Failback mailboxes?
by Dag Nygren 16 Aug '17

16 Aug '17

Hi! Have been using Fedora as my dovecot server for some time and am struggling with systemd at every update. Fedora insists on setting ProtectSystem=full in both dovecot.service and postfix.service at every update of the packages. This makes my mailstore which is in /usr/local/var/mail Read-only. And this makes the incoming emails delivered through dovecot-lda disappear into /dev/null until I notice the problem and we lose incoming emails. My question is: Is there any way to set up a failback mailstore for these occasions? PS! I really hate systemd - Destroys the UNIX way of doing things with a heavy axe.... Best Dag

Question about mail_location
by Laura Steynes 16 Aug '17

16 Aug '17

In using mysql, in the configuration file we need to specify, in the user query, '/path/ as home, yet but in dovecot.conf, we also are setting mail_location, the same thing is it not, so unless I've missed something, do we still need to use the path as home in the user query? Do we only need set that if it differs from mail_location? Thanks

Noel, thanks again for help and explanations. (what went wrong for me, I thought I knew actual password, seeing the long random string in dovecot_mysql file, then assumed it must be hashed version of what I knew as password, anyhow, that part working now) V

migrating 2.1 to 3.x, sql pass scheme, pass value?
by voytek＠sbt.net.au 16 Aug '17

I'm trying to migrate from Centos 6/dovecot 2.1.17/mysql to new server on Centos 7/dovecot 2.2.31 (65cde28)/mariadb I've dumped on oldserver 'dovecot.conf' and used it on newserver doveconf -n > dovecot.conf also, transferred /etc/doveconf/*.conf I've also dumped MySQL 'vmail' and imported database, created user vmail, vmailadmin dumb question: should the password hash from oldserver work 'as is' on newserver..? (different machine, different SQL..) I've tried 'as is', then, attepmted to change both "default_pass_scheme" and 'password=' values, but, no luck postfixadmin works, I can login and see domains/mailboxes what default_pass_scheme should I use ? where/how do I take password= value ? when I attempt to login to pop, I see this: # doveadm stop # dovecot # telnet 127.0.0.1 110 Trying 127.0.0.1...
