encrypted storage on the fly using user's password without storing password on the server
by Alex Knowles 05 Mar '20

05 Mar '20

Hi all, I just joined the list. I've read through the mail-crypt plugin docs here https://doc.dovecot.org/configuration_manual/mail_crypt_plugin/ I'm still unclear (I'm not an expert) about the following: Is it possible to obtain on-the-fly encrypted storage using the user's password without the password being stored on the server? Basically a zero-knowledge solution. Theoretically this should be possible as the user provides the password when storing or retrieving emails. The above plugin docs don't make it clear for me whether it is supported. Could a kind clarify? I'd also be very grateful for a working conf as an example. Best wishes and thanks in advance, Alex.

[PATCH] lib-imap: imap-bodystructure: add test with empty header field

This causes the body structure to be incorrect. The RFC says it's fine o have empty header field values. --- This just adds a failing test, inspired from an e-mail spotted in the wild.

Dovecot autoexpunge
by Philip Colmer 03 Mar '20

03 Mar '20

Following a previous suggestion I'd received to turn on autoexpunge (https://dovecot.org/pipermail/dovecot/2020-February/118281.html) I'm now trying to confirm whether or not it is doing what I expect it to do. I've set the expiration to be 12 weeks (as shown below in the config) but a lot of the mailboxes have email in them that is much older. Reading http://dovecot.2317879.n4.nabble.com/Dovecot-2-2-20-autoexpunge-td54644.html, I've tried using "doveadm search -u user mailbox INBOX savedbefore 2w" to see if it finds any email that is older than 2 weeks (just as a test) and it doesn't. If I change "savedbefore" to be "sentbefore" then it works. If "autoexpunge" is dependent on "savedbefore" working then what do I need to do to fix this? Thanks.

dovecot-lmtp dont see otherMailbox record?
by pi0trek75 01 Mar '20

01 Mar '20

Hello Postfix + LDAP , Samba as LDAP server, Dovecot virtual_transport set in postfix to dovecot-lmtp ( for autoresponder support ) Users have their email aliases in the otherMailbox record For example, account_test@example-domain user has an alias: test@exmaple-domain Query from command line works fine: postmap -q test@example-domain ldap://etc/postfix/ad_virtual_ account_test/Maildir/ (The filter in the query ad_virtual_mailbox_maps2.cf looks like this: [cut] scope = sub query_filter = (&(objectclass=person)(|(mail= result_attribute= uid result_format = %u/Maildir/ ) However, sending an email to the alias test@example-domain ends: Feb 28 12:31:40 mbox-01 postfix/lmtp[13474]: 2367A6EF: to=<test@example-domain>, relay=mbox-01[private/dovecot- delay=0.05, delays=0.02/0/0.02, dsn=5.1.1, status=bounced (host mbox-01[private/dovecot-lmtp] said: 550 5.1.1 <test@example-domain> User doesn't exist: test@example-domain (in reply to RCPT TO command)) I modified dovecot-ldap.conf.ext: I changed: user_filter = (&(objectClass=person)(uid=%u) to: user_filter = (&(objectClass=person)(|(uid=% but that didn't solve the problem.

max number of connections per ip
by Esteban L 29 Feb '20

29 Feb '20

I have been haunted by the following error message or months, that we see using Thunderbird. Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server. If so, use the Advanced IMAP Server Settings dialogue to reduce the number of cached connections. If I change my location, via a VPN, the error message goes away and I can connect. I have edited my /etc/dovcot/conf.d/20-imap.conf file by adding the following: protocol imap { # Space separated list of plugins to load (default is global mail_plugins). mail_plugins = $mail_plugins imap_quota # Maximum number of IMAP connections allowed for a user from each IP address. # NOTE: The username is compared case-sensitively. mail_max_userip_connections = 500 } And, I still get the error message. I know myself, I have about 8-9 accounts, some with as many as 10 folders (I know each one count's as it's own mailbox), as does my partner--who would access the internet from my IP. Does that number really have to be like 10,000, or something? If so, why does it start out so small in the first place. If not, what else could I do to avoid this message going forward??

doveadm acl recursive
by Armin Schindler 28 Feb '20

28 Feb '20

Hello, I try to set acl settings on a public folder including its subfolders. There is no option for acting recursive. But the documentation says wildcards can be given on the mailbox name. But this doesn't work. No matter how the mailbox name is provided with a wildcard, doveadm always tells Mailbox doesn't exist. Folder example: public/project1 public/project1/subdir1 public/project1/subdir2 public/project1/subdir2/subsubdir3 Setting acl on the given mailbox works for all of them. But how can I set for "public/project1" and all its subfolders in one command? Even "doveadm mailbox list" gives the error above when using wildcard. (I also tried all combinations of quotes). Armin

dovecot 2 samba ad-dc

Helo you, I try to build a mail server based on Centos 7, postfix and dovecot 2. My backend is a Samba4 ad-dc. I tried a lot and I don't know what else I could try.I'm new to this mailing list so please forgive me if I don't give right information or anything Samba4 ad-dc is up incl. dns. Win10 Client joined domain and authentication works. Postfix is up and checks against ldap whether recipient address exists. It takes mail via telnet and queues them. But can't give it to dovecot. my master.cf locks like that: [root@mail1t postfix]# cat master.cf smtp inet n - - - - smtpd submission inet n - - - - smtpd -o smtpd_enforce_tls=yes -o smtpd_tls_security_level=encrypt -o tls_preempt_cipherlist=yes pickup fifo n - - 60 1 pickup cleanup unix n - - - 0 cleanup qmgr fifo n - n 300 1 qmgr tlsmgr unix - - - 1000? 1 tlsmgr rewrite unix - - - - - trivial-rewrite bounce unix - - - - 0 bounce defer unix - - - - 0 bounce trace unix - - - - 0 bounce verify unix - - - - 1 verify flush unix n - - 1000? 0 flush proxymap unix - - n - - proxymap proxywrite unix - - n - 1 proxymap smtp unix - - - - - smtp relay unix - - - - - smtp showq unix n - - - - showq error unix - - - - - error retry unix - - - - - error discard unix - - - - - discard local unix - n n - - local virtual unix - n n - - virtual lmtp unix - - - - - lmtp anvil unix - - - - 1 anvil scache unix - - - - 1 scache maildrop unix - n n - - pipe flags=DRhu user=vmail argv=/usr/bin/maildrop -d ${recipient} uucp unix - n n - - pipe flags=Fqhu user=uucp argv=uux -r -n -z -a$sender - $nexthop!rmail ($recipient) ifmail unix - n n - - pipe flags=F user=ftn argv=/usr/lib/ifmail/ifmail -r $nexthop ($recipient) bsmtp unix - n n - - pipe flags=Fq. user=bsmtp argv=/usr/lib/bsmtp/bsmtp -t$nexthop -f$sender $recipient scalemail-backend unix - n n - 2 pipe flags=R user=scalemail argv=/usr/lib/scalemail/bin/scalemail-store ${nexthop} ${user} ${extension} mailman unix - n n - - pipe flags=FR user=list argv=/usr/lib/mailman/bin/postfix-to-mailman.py ${nexthop} ${user} dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${user}@${nexthop} #smtp inet n - n - 1 postscreen #smtpd pass - - n - - smtpd #dnsblog unix - - n - 0 dnsblog #tlsproxy unix - - n - 0 tlsproxy postlog unix-dgram n - n - 1 postlogd my ldap.conf on mailserver: [root@mail1t openldap]# cat ldap.conf # # LDAP Defaults # # See ldap.conf(5) for details # This file should be world readable but not world writable. #BASE dc=example,dc=com #URI ldap://ldap.example.com ldap://ldap-master.example.com:666 URI ldaps://ldap1t.test.loc:636 #SIZELIMIT 12 #TIMELIMIT 15 #DEREF never #TLS_CACERTDIR /etc/openldap/certs TLS_CACERTDIR /etc/pki/tls/certs/ka # Turning this off breaks GSSAPI used with krb5 when rdns = false SASL_NOCANON on TLS_REQCERT never dovecot.conf: [root@mail1t dovecot]# cat dovecot.conf auth_mechanisms = plain login mail_uid = vmail mail_gid = vmail ssl_cert = </etc/ssl/mail.pem ssl_key = </etc/ssl/key.pem login_log_format_elements = "user=<%u> method=%m rip=%r lip=%l mpid=%e %c %k" #mail_plugins = quota ssl_cipher_list = EDH+CAMELLIA:EDH+aRSA:EECDH+aRSA+AESGCM:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH:+CAMELLIA256:+AES256:+CAMELLIA128:+AES128:+SSLv3:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!DSS:!RC4:!SEED:!ECDSA:CAMELLIA256-SHA:AES256-SHA:CAMELLIA128-SHA:AES128-SHA log_timestamp = "%Y-%m-%d %H:%M:%S " log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log debug_log_path = /var/log/dovecot-debug.log #auth_verbose=yes auth_debug=yes auth_debug_passwords=yes mail_debug=yes verbose_ssl=yes protocols = imap listen = * auth_cache_size = 50000 # ~ 200 Benutzer mit Passwort auth_cache_ttl = 300s # in Sekunden, 5 Minute auth_cache_negative_ttl = 30s # wenn Benutzer nicht existierte bei letztem Check passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } service auth { unix_listener /var/spool/postfix/private/auth_dovecot { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { mode = 0600 user = root } user = root } service dict { unix_listener dict { mode = 0660 user = vmail group = vmail } } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = } protocol imap { mail_plugins = quota imap_quota } plugin { quota = maildir:User quota } dovecot-ldap.conf.ext: root@mail1t dovecot]# cat dovecot-ldap.conf.ext #hosts = 192.168.122.30:636 # Windows Active Directory uris = ldaps://192.168.122.30:636 #dn = CN=DovecotAdministrator,OU=ServiceAccounts,OU=Identitiy,DC=test,DC=loc dn = CN=Administrator,CN=Users,DC=test,DC=loc dnpass = Test123!

dovecot-uidlist....
by Chi Min Wang 27 Feb '20

27 Feb '20

Hello Everyone: Is it possible to direct dovecot to modify dovecot-uidlist automatically?? I have some user who use ancient MUA(i.e. Openwebmail) and IMAP/POP3. Since Openwebmail will insert "Status: R" in the eml file,the size of the eml file will increase by 10 bytes. If the user use Openwebmail first,then the size record(S=xxxx) in dovecot-uidlist will be fine. But if he use POP3/IMAP(dovecot) first then use Openwebmail,the size record in dovecot-uidlist will not match the actual size modified by Openwebmail. This will cause dovecot killed by core dump. I'm wondering if there are any method to avoid this situation,Thanks!! *********************************************** CONFIDENTIALITY NOTICE:This e-mail and any attachments are confidential and may be legally privileged.
