[Dovecot] SMTP Proxy
by Leonardo Rodrigues 26 Aug '13

26 Aug '13

Hi, I have found a message on this mailing list dated August/2012 in which is said that dovecot could not (at least at that time) do SMTP Authentication using Proxy Features. http://www.dovecot.org/list/dovecot/2012-August/067998.html is this still true, given i'm using latest stable dovecot, v2.2.5 ? extra informations ... smtp authentication is done by postfix using: dovecot: service auth { unix_listener /var/spool/postfix/private/auth { mode = 0660 user = postfix group = postfix } } postfix: smtpd_sasl_type = dovecot smtpd_sasl_path = /var/spool/postfix/private/auth Thanks ! -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

Hello, I am trying to move/copy a virtual user's maildir to another virtual user but am running into problems with dsync and doveadm. I'm trying to move the maildir of a user who is no longer with the company to a manager's maildir. For doveadm I am using the command: doveadm move -u scavenaugh(a)lamontanita.coop jhenning(a)lamontanita.coop/INBOX/scavenaugh INBOX ALL The error is: doveadm(scavenaugh(a)lamontanita.coop): Error: user scavenaugh(a)lamontanita.coop: Auth USER lookup failed /var/log/dovecot.log shows: passdb doesn't support lookups, can't verify user's existence dovecot -n # 2.1.6: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-RELEASE i386 ufs auth_cache_ttl = 14 mins auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain gssapi login auth_use_winbind = yes auth_verbose = yes auth_winbind_helper_path = /usr/local/bin/ntlm_auth first_valid_gid = 1001 first_valid_uid = 1001 info_log_path = /var/log/dovecot_info.log last_valid_gid = 1001 last_valid_uid = 1001 log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:/usr/data/vmail/%u mail_max_userip_connections = 30 mail_privileged_group = mail passdb { args = /usr/local/etc/dovecot-ldap.conf driver = ldap } plugin { sieve = /usr/data/sieve-scripts/%u.sieve } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 } user = root } ssl_cert = </etc/ssl/dovecot/04JAN12cert.pem ssl_key = </etc/ssl//dovecot/04JAN12key.pem userdb { args = uid=vmail gid=vmail home=/usr/data/vmail/%u driver = static } valid_chroot_dirs = /usr/data/vmail verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve sendmail_path = /usr/sbin/sendmail } Your assistance is greatly appreciated.

[Dovecot] A question of imap timeout exit
by 刘莹莹 26 Aug '13

26 Aug '13

hello: I have a question on imap process: if a client connect to dovecot like foxmail(version 10) , dovecot will start at least 3 imap processes , and these imap processes will online until client logout , if the client not logout ,the imap process will always online. this is similar to the long connection and imap's auto logout timer is not effect in this case. now I have two questions: 1: if there are a large number of users online at the same time ( eg about 30 000 users): so dovecot should shart at least 30 000 * 3 imap processes, if user not logout ,so many processes are online all the time .this is terrible. I dot'n know if there is a solution ?? now I have changed the timeout = 2min and test ,dovecot active disconnected imap process ,but I don't think this is a appropriate option. 2: I want to know why auto logout timer duration of IMAP protocol must be not less than 30 minuters ?? My English is not vary good ,I'm sorry but I really want to know the answer . thanks

[Dovecot] dovecot OK for intranet, not OK for external IPs
by Sulla 25 Aug '13

25 Aug '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear all! I'm stuck. I've got a dovecot IMAP server running (TLS, port 149) on Ubuntu 13.04 server behind a DSL router. The mailserver's IP is 10.0.0.1 When I connect to my mailbox from my intranet-PC (10.0.0.2), everything works as expected. Login OK, acces to all mailboxes is ok, everything. netstat -nt on my email server shows me: Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 10.0.0.1:143 10.0.0.2:57952 ESTABLISHED and /var/log/mail.log shows me: Aug 24 22:41:00 SERVERNAME dovecot: imap-login: Login: user=<UID>, method=PLAIN, rip=10.0.0.2, lip=10.0.0.1, mpid=24326, TLS, session=<3Ul+irfkYAAKAAAC> However, when I connect to my mailserver through the internet (from 10.196.124.7 which is a modem of my ISP), dovecot ignores the authentication request. It does nothing. Just nothing. My router forwards the connection request to my mailserver correctly, so port forwarding on the router is ok, as my mailserver gets a connection request from the client. Proof: "netstat -nt" shows me: Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 10.0.0.1:143 10.196.124.7:1024 SYN_RECV So, my server gets a connection request on port 143 from my client PC, but then nothing happens. By nothing I mean, that nothing gets written into /var/log/mail.log and my email client (Thunderbird) gets a connection timeout. Any ideas why dovecot is refusing connections? How can I solve this problem? thanx all Sulla -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlIZI7sACgkQR6b2EdogPFvqxACgrUACK1J8tHCxJR0jMUui14bs TsoAnAw4QnVr2kydjk2cErKW+i6oVu1f =86wg -----END PGP SIGNATURE-----

OK, I did read <http://wiki2.dovecot.org/LDA> but it doesn't answer the question I have since it doesn't tell me what I can do with -o, exactly. What I would like to do is be able to call dovecot-lda and pass along '\\Seen', is that possible? -- Up the airy mountains, down the rushy glen...

[Dovecot] SSL Cipher Order in Dovecot
by Marc Grooz 23 Aug '13

23 Aug '13

Hi, I want that dovecot uses PFS with my Apple Devices. I set the Cipher List to: ssl_cipher_list = DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!CBC:!PSK:!SRP:!DSS:!SSLv2:!RC4 I got this from here: http://www.kuketz-blog.de/perfect-forward-secrecy-mit-apple-mail/ But then my only Outlook 2010 Client won't connect. If i enable rsa-aes128-SHA again on third place all clients connect without dhe. Dosen't dovecot horner the Cipher Order in the config? Kind regards Marc
