[Dovecot] Fail2ban and logging
by Paul van der Vlis 17 Jul '13

17 Jul '13

Hello, Dovecot is logging authentication failures this way: ------ Jul 12 18:07:19 vps0 dovecot: imap-login: Disconnected (auth failed, 22 attempts in 172 secs): user=<info>, method=PLAIN, rip=82.95.148.152, lip=1.2.3.4, TLS, session=<QylMqlLhVwBSX5SY> ------ Fail2ban is trying to catch them with this regex: ------ failregex = .*(?:pop3-login|imap-login):.*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed).*rip=(?P<host>\S*),.* ------ This way fail2ban is counting 22 attempts as 1 attempt... I expect I need to change something on the logging, so that every attempt is seperate logged. But I don't know how. Is here somebody who knows how to get fail2ban correct working? No help on this on the wiki's: http://wiki1.dovecot.org/HowTo/Fail2Ban http://wiki1.dovecot.org/Logging http://www.fail2ban.org/wiki/index.php/Dovecot With regards, Paul van der Vlis. -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl/

Hi everybody, I'm trying to configure the expire plugin, unsuccessfully. This is my configuration, the part related to this plugin. Could somebody give a look to it? I can not figure out why is not working :-S. Thank you, and regards!

[Dovecot] courier to dovecot
by J Gao 17 Jul '13

17 Jul '13

Hi, All, I am new here and I need your advises. Here is my story: I have a mail server like this: - CentOS 5 32 bit (LAMP) - Postfix 2.3 - Courier - MailScanner Courier use maildir to save emails in /home/vmail/<virtual domain>/<user> / Now I want to build a new system on CentOS 6.4 64bit with postfix, dovecot and migrate all user accounts and their emails. I already installed CentOS 6.4, postfix and mysql. Also just installed Dovecot v2.2.4 from the RPM. Now I am looking into how to Is there a good instruction on how to do this kind of migration? I still prefer using the maildir system. If I just copy all users email from old server to new dovecot user maildir, will dovecot see these mails (and sub-folders) ? Do I need do anything extra? Thanks in advance. Gao -- __ _|==|_ ('')__/ >--(`^^') (`^'^'`) `======'

[Dovecot] reload without shutting imap connections down
by Hajo Locke 16 Jul '13

16 Jul '13

Hello, we have some problems with users who report connectionproblems to dovecot sometimes. According to the logs there are dovecot reloads at this times. Seems that a reload also causes dovecot to shut all imapconnections down: Jul 16 13:31:40 myhostname dovecot: master: Warning: SIGHUP received - reloading configuration Jul 16 13:31:40 myhostname dovecot: imap: Server shutting down. bytes=251/675 I tried to reload by initscript or sending -HUP manually to pid, dovecot is shutting down imapconnections and i think this is the reason for users to report this problems with some clients. This seems to be new with versions 2.x, i have some old 1.2.x dovecots running and cant find "Server shutting down" in their logs after reload. I have still potential to reduce reloads, but cant avoid them completely. Is there a workaround? Thanks, Hajo

[Dovecot] Difference between using auth_realms and setting up virtual mailboxes in postfix?
by Gab IIpop 16 Jul '13

16 Jul '13

Hi, there is a possibility in the future that I might have to support multiple domain names(but using the same IP address). Postfix has something called 'virtual mailboxes' to help handle this. But I also noticed that dovecot has a setting "auth_realms" where I can specify domains separated by a space. What is the relationship between the two?

[Dovecot] mail not reject when the mailbox is full (Dovecot-LDAP-Imap_quota)
by Victor Oñate 16 Jul '13

16 Jul '13

Hello List. Currently I have configured the share of users through the LDAP query as shown #dovecot.conf protocol imap { mail_plugins = quota imap_quota } plugin { quota = dirsize } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } #dovecot-ldap.conf auth_bind = yes ldap_version = 3 base = dc=XXX,dc=YY,dc=ZZ deref = never scope = subtree user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mail=Maildir,mailQuotaSize=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password,homeDirectory=userdb_home,uidNumber=userdb_uid,gidNumber=userdb_gid pass_filter = (&(objectClass=posixAccount)(uid=%u)) Additionally in thunderbird customers have the plug so they can see the share. This works perfect! However, when the mailbox exceeds 100% users continue to receive mail which makes the risk set allocated disk space, the idea is that when full the mail reject with a message "mailbox XXX full" . As always appreciate the ideas. Victor Oñate

[Dovecot] Proxying improvements in v2.1.2
by Timo Sirainen 16 Jul '13

16 Jul '13

I just committed a couple of features that will make life easier for some types of proxying setups: 1. IMAP proxying has already for a while supported sending local/remote IP/port to backend server, which can use it for logging and other purposes. I've now implemented this for POP3 as well, although only the remote IP/port is forwarded, not local IP/port. I implemented this also for LMTP in v2.2 tree, but haven't bothered to backport that change. Both POP3 and LMTP uses XCLIENT command that is compatible to Postfix's (XCLIENT ADDR=1.2.3.4 PORT=110). 2. proxy_maybe=yes + host=host.example.com actually works now. As long as host.example.com DNS lookup returns one IP that belongs to the current server the proxying is skipped. 3. auth_proxy_self = 1.2.3.4 setting means that if proxy_maybe=yes and host=1.2.3.4 then Dovecot assumes that this is a local login and won't proxy it, even if 1.2.3.4 isn't the actual local IP. This can be helpful if the host field contains load balancer's IP address instead of the server's. You can add more than one IP (space separated) and of course everything related to this works just as well with hostnames as with IPs (even when hostname expands to multiple IPs).

[Dovecot] Sieve vacation variables reference
by Simon 16 Jul '13

16 Jul '13

Hi There. We are using dovecot v2.2.4 with pigeonhole 0.4.1 (both compiled from source) Centos 6.4. Sorry for the dumb question in advance if I'm just missing an obvious link somewhere (also if I've got the terminology all wrong!), but could someone point me to the reference list for "vacation", e.g.: vacation :days :subject :addresses :from is there a definitive list of things like "days", "subject" etc? Thanks Simon

[Dovecot] Sieve scripts in mysql?
by Simon 16 Jul '13

16 Jul '13

Hi There. We are using dovecot v2.2.4 with pigeonhole 0.4.1 (both compiled from source) Centos 6.4. We are storing our virtual user config in mysql. At the moment we are storing our sieve script configs in mysql and then running a script to write these out to a file.. But I'm wondering if there a way to store sieve scripts in mysql? Many thanks!

[Dovecot] Services not starting in 2.1 (or 2.2)
by Tommy Wareing 16 Jul '13

16 Jul '13

I'm trying to install Dovecot onto my QNAP NAS. I apologise for this! It means I'm not working in a normal environment, and don't (necessarily) have the normal range of tools available (or the most up to date version of those tools). It seems that 2.0.21 works (at least, as far as I've tested), but 2.1.17 and 2.2.4 won't start up their child services. I've got the source code for all three from http://www.dovecot.org/download.html, and, for experimental purposes, I'm configuring with: ./configure --prefix=/opt The configure script ends by reporting: Install prefix . : /opt File offsets ... : 64bit I/O polling .... : epoll I/O notifys .... : inotify SSL ............ : yes (OpenSSL) GSSAPI ......... : no passdbs ........ : static passwd passwd-file shadow checkpassword : -pam -bsdauth -sia -ldap -sql -vpopmail userdbs ........ : static prefetch passwd passwd-file checkpassword nss : -ldap -sql -vpopmail SQL drivers .... : : -pgsql -mysql -sqlite The dovecot.conf I'm using, at the moment, is the absolute minimal to fire things up: protocols = imap listen = * ssl_cert = </opt/etc/ssl/certs/dovecot.pem ssl_key = </opt/etc/ssl/private/dovecot.pem dovecot -n is happy, and reports those four lines back to me. When I start this up, I get, in /var/log/messages file: Jul 10 10:09:28 QNAP mail.info dovecot: master: Dovecot v2.0.21 starting up (core dumps disabled) and ps shows: [admin@qnap dovecot]# ps -ef | grep dovecot admin 11478 1 0 10:09 ? 00:00:00 /opt/sbin/dovecot dovecot 11479 11478 0 10:09 ? 00:00:00 dovecot/anvil admin 11480 11478 0 10:09 ? 00:00:00 dovecot/log admin 11482 11478 0 10:09 ? 00:00:00 dovecot/config admin 11525 455 0 10:10 pts/5 00:00:00 grep dovecot All is right with the world! Well, until I try to use dovecot properly, at which point I'll need a full configuration. But it's alright so far! :) However, if I go through the same routine with Dovecot 2.1.17, I get the appropriate message in messages: Jul 10 10:12:45 QNAP mail.info dovecot: master: Dovecot v2.1.17 starting up (core dumps disabled) But this time, ps shows: [admin@qnap dovecot-2.1.17]# ps -ef | grep dovecot admin 15259 1 0 10:12 ? 00:00:00 /opt/sbin/dovecot admin 15294 455 0 10:12 pts/5 00:00:00 grep dovecot and the child services don't seem to have started. This is born out by the fact that no network connections work: they stall, and then eventually time out (telnet localhost 143 produces no output at all, until I disconnect it). Even dovecot stop has trouble, taking several seconds before it returns me to the prompt, and *not* killing the existing process. dovecot -n is still happy however (and in a full configuration, components which don't require the services seem to work properly, such as dovecot-lda, if it doesn't require auth). I'm not sure that I need those newer versions of dovecot, so I'll get back to version 2.0 for now. But I'd certainly like the option, and imagine that somebody else might care as to what the problem is! -- Tommy Wareing

[Dovecot] trying to configre dovecot
by Gene Heskett 15 Jul '13

15 Jul '13

Hi all; Thinking I'd like to have a bit of security, I followed the example for dovecot from allgoodthings.org Guessing between the lines I made a few substitutions to localize it for me, but when I run the line to dump the configs, the output is very short because I do not have the *.pem files. Where can a usable set of these ssl 'keyfiles' be obtained? Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

[Dovecot] User login for SMTP but not for IMAP/POP?
by Martin 15 Jul '13

15 Jul '13

Hello everybody, I have a question, though I'm not sure if it's a matter of dovecot or postfix. Or if it's even possible to do at all. If I understand it correctly, SMTP authentification is done via SASL. When a user wants to login Postfix queries an external user database (dovecot). Therefore the SMTP-users are identical to the IMAP/POP-users. I want to achieve the following: I want some user credentials (username&password) for a user that is able to login via SMTP, but who doesn't have a mailbox and therefore shouldn't be able to login via IMAP/POP. Is this even possible? How can it be achieved? Or: does this behaviour have a special name, which I can google for? Regards, Martin

[Dovecot] login_trusted_networks from webmail ?
by Jan-Frode Myklebust 15 Jul '13

15 Jul '13

I'd like to get the IP-address of the webmail-klient logged in my maillog (for being compliant with coming data retention policies). I've noticed that with login_trusted_networks pointing at my dovecot directors, we get rip=client-ip logged on the backends. How is the proxy providing this to the dovecot backends? Anybody know what magic we need to implement in our webmail-solution to be able to forward the webmail-client-ip and have it logged as rip= in dovecot? I belive it will be enough to have it logged as rip= on the directors, maybe not needed to be forwarded all the way to the backends (but that would be nice as well). -jf

[Dovecot] new user questions
by Gene Heskett 14 Jul '13

14 Jul '13

Greetings; Trying to follow along with the wiki2 setup instructions and thought I'd hit a snag with the first "send me a mail" snippet as it took several minutes to arrive, so I assume that somehow procmail was involved in the delivery and my procmail runs mail thought a whole bunch of checks before finally handing it off to a mailfile as /var/mail/gene. Then the next script seems to only try whats in my home dir, and of course doesn't find it as neither exists, yet... I assume that is because dovecot needs a kill -HUP. But I am not familiar with that, so how is it done, and as what user, me, or root, on a ubuntu 12.04.2 LTS install? Thanks.

[Dovecot] Mail replication ... totally confused !
by HL 13 Jul '13

13 Jul '13

Hello, I am totally confused configuring replication in dovecot. In my case I have 2 servers instead of running rsync as a daemon which takes a lot of time I would like SERVER-A will be the master and SERVER-B will be the slave My users directly interact with server A, Server B stands as a mails backup only I've setup SERVER-B ( backup ) like that, NO SPECIAL CONF on master SERVER-A Is this ok ?? I Don't want to miss any mails Since this is a live server service aggregator { # give enough permissions for mail processes # fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } service replicator { # start replication at startup # process_min_avail = 1 } service doveadm { # if you're using a single virtual user, set this to start ssh as vmail # (not root) # user = vmail } service config { # needed to grant access to /var/run/dovecot/config for service doveadm # unix_listener config { user = vmail } } dsync_remote_cmd = ssh -p 1234 -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} plugin { mail_replica = remote:vmail@master-server-a.tld replication_full_sync_interval = 1 hours }

[Dovecot] Ambiguous behavior with prefetch database?
by Axel Luttgens 13 Jul '13

13 Jul '13

Hello, Let's say dovecot.conf contains: mail_uid = dovemailer mail_gid = dovemailer mail_home = /some/path/%n mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox and that the password database query is of the form: password_query = \ SELECT \ passwd AS password, \ nickname AS user, \ mail_home AS userdb_home, \ mail_location AS userdb_mail, \ WHERE \ ... The database initially comes with NULL for both mail_home and mail_location, the goal being to be able to progressively replace legacy settings. With the above, one gets such entries in the logs upon a pop or imap connection: auth-worker(11262): Debug: auth(u12345678,127.0.0.1): username changed u12345678 -> john.doe auth: Debug: auth(u12345678,127.0.0.1,<dsNsasbgRQB/AAAB>): username changed u12345678 -> john.doe [...] auth: Debug: prefetch(john.doe,127.0.0.1,<dsNsasbgRQB/AAAB>): passdb didn't return userdb entries, trying the next userdb and, of course, the userdb_query fails since it isn't supposed to be invoked under such circumstances. Of course, the userdb_query could be adapted so as to handle pop/imap connections in addition to say, lmtp or doveadm connections, but this would anyway raise the question: why bother with a prefetch database setup? In fact, it seems that the problem comes from the fact that the password_query returns NULL values (i.e. "do not override dovecot.conf settings") for all userdb_xxx settings even if, technically speaking, it returns such columns. A slight yet somewhat silly modification of the password_query, such as this one: password_query = \ SELECT \ passwd AS password, \ nickname AS user, \ 'dovemailer' AS userdb_uid, \ mail_home AS userdb_home, \ mail_location AS userdb_mail, \ WHERE \ ... indeed seems to bring back all the expected behavior: now, the "passdb returns userdb entries" and, for example, the config's mail_home expands to the expected value /some/path/john.doe. Could it be that the case "userdb_xxx columns returned, even if all with NULL values" has been somehow overlooked in the code? Or am I erring with my interpetation of all those matters? TIA, Axel

[Dovecot] A sqlite-based quota dict
by Axel Luttgens 13 Jul '13

13 Jul '13

Hello, While experimenting with the sqlite backend, I noticed a big vacuum wrt its use for a quota dict. This is thus an opportunity to share a solution I managed to devise after some trials and errors and a (very quick and unscientific) look at the code. And also the opportunity to ask the community to check for possible flaws. Yes, nothing comes for free... ;-) TIA, Axel This is the SQL for creating the database or for adding needed table/trigger to an existing database (with many comments and few "active" lines): CREATE TABLE quota ( -- We will assume that, in the case of a sqlite DB (and probably a pgsql DB -- as well), Dovecot will *always* act along these lines: -- In case of a "row creation": -- INSERT INTO quota (subject, byte_count) -- VALUES (<some id>, <byte count>); -- INSERT INTO quota (subject, message_count) -- VALUES (<some id>, <msg count>); -- In case of a recalculation: -- UPDATE quota -- SET byte_count = byte_count + <byte count diff>, -- message_count = message_count + <msg count diff> -- WHERE subject = <some id>; -- In case of a row deletion: -- DELETE FROM quota -- WHERE subject = <some id>; -- For example, a "doveadm quota recalc" may first delete the relevant row -- if it exists, then (re-)create it. -- Clearly, the "row creation" case is a bit problematic, hence the need for -- a trigger. -- An id for the entity subjected to a quota (a user/mailbox, a domain...). subject TEXT PRIMARY KEY NOT NULL, -- The entity's size, expressed as a storage space use and as a message -- count. -- Note the NULL defaults: they allow to simplify the trigger's logics. byte_count INTEGER DEFAULT NULL, message_count INTEGER DEFAULT NULL ); CREATE TRIGGER quota_insert BEFORE INSERT ON quota FOR EACH ROW BEGIN -- If there's a row to update, that's because the first INSERT of the "row -- creation" has been performed. -- (this UPDATE could probably be simplified if the insertion order, -- byte_count then message_count, was guaranteed; anyway, since the "row -- creation" operation shouldn't be very frequent, we may afford a slight -- inefficiency). UPDATE quota SET byte_count = CASE WHEN NEW.byte_count ISNULL THEN byte_count ELSE NEW.byte_count END, message_count = CASE WHEN NEW.message_count ISNULL THEN message_count ELSE NEW.message_count END WHERE subject = NEW.subject; -- In which case we may ignore that second (current) INSERT, since the -- previously inserted row has just been updated with the value coming -- from the current INSERT statement. SELECT raise(IGNORE) WHERE EXISTS (SELECT * FROM quota WHERE subject = NEW.subject); END; The corresponding dict configuration being thus supposed to be similar to this one: connect = /path/to/database map { pattern = priv/quota/storage table = quota username_field = subject value_field = byte_count } map { pattern = priv/quota/messages table = quota username_field = subject value_field = message_count }

[Dovecot] Dovecot Virtual Folders... could these be managed by a/the Client?
by Charles Marcus 12 Jul '13

12 Jul '13

Hi all/Timo, I was thinking about Thunderbirds ability to create Virtual folders allowing you to have many different views of your messages... The downside though, is you only see these in Thunderbird. I know that dovecot supports server side virtual folders: http://wiki2.dovecot.org/Plugins/Virtual But I'm wondering about the possibility to manage these from the client side... For example, would it be possible to create an extension in Thunderbird that allowed the user to manage these (create, edit the filters for, delete, rename, etc)? Thanks, -- Best regards, Charles

[Dovecot] (no subject)
by Gab IIpop 12 Jul '13

12 Jul '13

>From the documentation, virtual users seem like a good idea if you plan on having a lot of users. Although I'm wondering about the following: What other benefits/consequences are there to using virtual over system users and vice versa? Will virtual users have the same protection as system users (system users would use linux permissions, which is pretty secure)? How easy will it be to switch from using system users to virtual users or vice versa?

[Dovecot] avoid log message when using nagios check
by lluis 12 Jul '13

12 Jul '13

Hello, I'm using a nagios check to monitor dovecot status, since dovecot v2 I see those syslog messages on every nagios check: pop3-login: Aborted login (no auth attempts in 0 secs) imap-login: Aborted login (no auth attempts in 0 secs) I tried to avoid those messages sending a logout string: check_imap -H localhost -e 'OK' -s 'a logout' check_pop -H localhost -e 'OK' -s 'quit' but now I get imap-login: Disconnected (no auth attempts in 0 secs) pop3-login: Disconnected (no auth attempts in 0 secs) what can I do to avoid a log message on every nagios check? thanks!

[Dovecot] getting quota error when accessing private namespace
by Andreas Oster 12 Jul '13

12 Jul '13

Hi all, I have run into a problem which I cannot find a solution for. I have created an additional private namespace with the following commands in dovecot.conf : namespace { disabled = no hidden = no ignore_on_failure = no inbox = no list = children location = maildir:/var/vmail/archives/%Ln/Maildir mailbox "archived mails" { auto = subscribe driver = special_use = \Archive } prefix = Archives/ separator = / subscriptions = yes type = private } plugin { quota = maildir:User quota:ns= quota2 = maildir:Archives quota:ns=Archives/ quota2_rule = *:storage=5G quota_rule = *:storage=1G quota_rule2 = Trash:storage=+200M } I can access the new namespace without any problems but every time a folder in this namespace is accessed, I get the following error messages in mail.err log: dovecot: imap(testuser): Error: quota: Unknown namespace: Archives/ dovecot: last message repeated 49 times Quota seems to work, though I have the feeling, that it only will be updated when closing and reopening the mail client, but this can also be a client issue. Quota for the INBOX is either taken from LDAP or, if there is no value defined in LDAP, will be assigned a quota of 1G The Archives/ namespace has a static quota of 5G for every user. Does anyone have idea how to get rid of these error messages ? Thank you for your kind help Andreas

[Dovecot] Multiple Folders Continually Auto-Created
by Cassidy Larson 12 Jul '13

12 Jul '13

I've had reports of a number of clients running Outlook 2011 on Mac where they have quite a few folders with the same name appended by multiple "1"s. So far I've only narrowed it down to Outlook 2011 on Mac. We've been in the process of migrating to sdbox on a new server from maildir using dsync backup. Example folder structure: INBOX INBOX 1 INBOX 1 1 INBOX 1 1 1 INBOX 1 1 1 1 INBOX 1 1 1 1 1 INBOX 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 1 1 INBOX 1 1 1 1 1 1 1 1 1 1 Junk Junk 1 Junk 1 1 Junk 1 1 1 Junk 1 1 1 1 Junk 1 1 1 1 1 Junk 1 1 1 1 1 1 Junk 1 1 1 1 1 1 1 Junk 1 1 1 1 1 1 1 1 and so on for "Sent Messages", etc. Seems that the the default folders for these clients are getting created over and over again, each time with a new "1" at the end. Anybody else see this? I'm digging for a client I can troubleshoot with and reproduce with me watching. Thanks, -c

[Dovecot] SSL cert problem
by Peter von Nostrand 12 Jul '13

12 Jul '13

Hi, I'm running a new dovecot 2.0.9 under Centos 6.4. I'm having an issue with SSL certificate not being accepted by the email client. I have my own CA and I have generated certificates for web usage without a problem. For imaps and pop3s what I did was generate a certificate for the hostname of my dovecot server and then cat that cert with the intermediate and root CA certificates. No matter what thunderbird still complains with Unknown identity. # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-358.2.1.el6.x86_64 x86_64 CentOS release 6.4 (Final) auth_mechanisms = plain login auth_socket_path = /var/run/dovecot/auth-userdb auth_username_format = %n disable_plaintext_auth = no log_path = /var/log/dovecot.log mail_fsync = never mail_home = /vmail/%u mail_location = maildir:~/Maildir mail_plugins = quota managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mbox_write_locks = fcntl passdb { driver = pam } plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 lmtp sieve quota_full_tempfail = yes service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } service lmtp { unix_listener lmtp { user = vmail } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl_cert = </etc/pki/dovecot/certs/mail.pem ssl_key = </etc/pki/dovecot/private/mail.example.com.key userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_ssl = yes protocol lmtp { mail_fsync = optimized mail_plugins = sieve quota } protocol lda { mail_plugins = sieve quota } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota This is the log: Jul 11 15:38:45 imap-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv2/v3 read client hello A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read client hello A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write server hello A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write certificate A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write key exchange A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write server done A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 flush data [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read client key exchange A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read finished A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write session ticket A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write change cipher spec A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write finished A [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 flush data [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x20, ret=1: SSL negotiation finished successfully [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL: where=0x2002, ret=1: SSL negotiation finished successfully [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL alert: where=0x4004, ret=558: fatal certificate unknown [192.168.0.1] Jul 11 15:38:45 imap-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [192.168.0.1] Jul 11 15:38:45 imap-login: Info: Disconnected (no auth attempts): rip=192.168.0.1, lip=192.168.1.1, TLS: SSL_read() failed: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown: SSL alert number 46 Thx in advance -- Peter
