[SIEVE] pipe :copy to external program with arguments
by spamvoll＠googlemail.com 02 Aug '18

02 Aug '18

Hi all, quick questions about sieve pipe: I want to pipe spam messages to an external program with additional parameters my spamlearn.sieve script: require ["vnd.dovecot.pipe", "copy", "imapsieve"]; pipe :copy "mybin" ["-h 127.0.0.1:44444" , "markspam"]; I also tried: pipe :copy "mybin" ["-h 127.0.0.1:44444 markspam"]; pipe :copy "mybin" ["-h 127.0.0.1:44444"] ["markspam"]; pipe :copy :args ["-h 127.0.0.1:44444 markspam"] "mybin" ; It never executes correct, it always ends with: Error: sieve: Execution of script /my/path/to/spamlearn.sieve failed So whats the correct syntax ? What works is a single argument: pipe :copy "myscript" ["markspam"]; Dovecot Version 2.3.2.1

Basic question about file permissions for sieve error log

Hello, I have an admittedly very basic question, but I am not able to get it to work. I store my global sieve script in: /etc/dovecot. I recently made a mistake in my global sieve script which causes Dovecot to attempt to log the errors in: /etc/dovecot/sieve-global.log In /var/log/dovecot.log I see: Jul 24 15:33:32 lmtp(test(a)example.com): Error: ABVWGAx/V1uKLAAA1B5X9w: sieve: failed to open logfile (LOGGING TO STDERR): open(/etc/dovecot/sieve-global.log) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /etc/dovecot, we're not in group 122(dovecot), dir owned by 0:122 mode=0775) …but the group membership shows: $ sudo -u vmail groups vmail dovecot …and I restarted Dovecot, but the same error happens. What am I doing wrong ? Thanks, - J

question about using procmail
by Joe Wong 01 Aug '18

01 Aug '18

Hello, I am new to Dovecot, testing the setup with Solr FTS plugin. Currently I am using procmail to delivery email into user's mailbox. I am using maildir on file system. I found that if email is delivered via procmail, the indexer-worker is not being called. But when I move the email between folders via IMAP, indexer is involved. Is this expected? - Joe

Almost there with Sieve
by Danny Horne 31 Jul '18

31 Jul '18

Hi all, Dovecot - 2.2.35 Pigeonhole - 0.4.23 I've recently moved mail filtering from local filtering (using Thunderbird) to Sieve. I've got filtering into folders and flagging emails working fine, but for possibly one tiny glitch. When specifying folders to filter into I have to use the format 'INBOX/Folder name' instead of just 'Folder name'. Can this be corrected? No real biggie but would be nice if it could.

Well, I don't know about yuuuge security risk (not saying there isn't any...), but if this concerns you, you can also use LTMP instead, which is probably a better solution here.

2.3.2.1 - EC keys suppport?
by ѽ҉ᶬḳ℠ 31 Jul '18

31 Jul '18

Hi, facing [ no shared cipher ] error with EC private keys. This happens when the private key is generated with [ openssl ecparam -name brainpoolP512t1 -genkey ] with OpenSSL 1.1.0hh on the same machine Dovecot is running on. Tried some variations of [ ssl_cipher_list ] but to no avail - the [ no shared cipher ] error persists. Once the key is generated with [ openssl genpkey -algorithm RSA ] however the error is gone. Thus wondering whether (1) I am missing something or (2) this a bug or (3) there is no support for EC keys?

Welcome plugin - user and domain vars?
by Tony 31 Jul '18

31 Jul '18

Hi List, I have multiple mail domains and depending on the domain name was looking for a way to pass the user and domain into a welcome.sh script. I looked at the quota script and saw of the 3 vars one of them is for the user. BOUNDARY="$1" USER="$2" MSG="" For the username - could we still reference USER="$2" in order to pass the username in the welcome email or is this only supported with the quota plugin? For the domain - how could one pass the 1st time login user's mail domain to the script? I looked at the welcome-plugin.c source, but didn't find anything that might reference a domain. Ideally I was hoping maybe something similar to the quota script could work.. MSG="" if [[ "$DOMAIN" = "domain.net" ]]; then MSG="..." elif [[ "$DOMAIN" = "domain.com" ]]; then MSG="..." elif [[ "$DOMAIN" = "domain.me" ]]; then MSG="..." elif [[ "$DOMAIN" = "domain.email" ]]; then MSG="..." fi Thanks for any suggestions. Cheers, Tony

uid problem
by Andras Kemeny 31 Jul '18

31 Jul '18

hi, contacting this mailing list is my last-ditch effort to somehow come to a working configuration where postfix "ends in" dovecot, IE for special LDAP-based users, featured in the virtual mailbox delivery, dovecot would act as LDA. here's the deal. i've set up dovecot's access to the LDAP server, and for the purposes of being an IMAP server and a SASL auth backend, dovecot works brilliantly and without a glitch. i can access my test mailbox (in maildir format), i can use the LDA as root and it delivers the message correctly (after a switch to the target user's UID), and even postfix's submission works with dovecot as its SASL backend. what does not work is dovecot as LDA from postfix. i'm getting these errors in the log: Jul 31 03:40:40 rhyno dovecot: lda(aik): Error: user aik: Auth USER lookup failed Jul 31 03:40:40 rhyno dovecot: auth: Error: userdb(aik): client doesn't have lookup permissions for this user: userdb uid (10001) doesn't match peer uid (5000) (to bypass this check, set: service auth { unix_listener /var/run/dovecot/auth-userdb { mode=0777 } }) Jul 31 03:40:40 rhyno dovecot: lda: Fatal: Internal error occurred. Refer to server log for more information. for the sake of clarity, i've tried the "to bypass this check" instructions, didn't help. also, for the sake of operational clarity, "aik" is the LDAP account with the following parameters: dn: uid=aik,ou=People,dc=rhyno,dc=tech objectClass: account objectClass: posixAccount objectClass: postfixUser cn: aik uid: aik uidNumber: 10001 gidNumber: 10001 homeDirectory: /home/aik loginShell: /bin/sh gecos: aik description: User account structuralObjectClass: account entryUUID: db947584-0369-1038-98b3-675e2f0cea17 creatorsName: cn=admin,dc=rhyno,dc=tech createTimestamp: 20180613152616Z email: *********** userPassword:: ************************* mailacceptinggeneralid: andras.kemeny mailacceptinggeneralid: kemeny.andras mailacceptinggeneralid: aik mailacceptinggeneralid: pdx mailacceptinggeneralid: @rhyno.tech mailacceptinggeneralid: @rhynotechnologies.com maildrop: aik and postfix's master.cf says: dovecot unix - n n - - pipe flags=ODRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -e -f ${sender} -d ${user} so i'm stuck at this point. obviously, if the LDA is spawned with vmail:vmail perms, it cannot become uid 10001 (btw, the LDAP and passwd accounts were once connected, but for security reasons, the connection has been severed -- still the /home/aik/mail dir is owned by uid 10001 etc). what am i doint wrong? thanks, a

dovecot 2.3.x, ECC and wildcard certificates, any issues
by David Mehler 31 Jul '18

31 Jul '18

Hello, Does dovecot 2.3.x have any issues recognizing or using certificates that are ECC and wildcard? I'm trying to switch my letsencrypt implementation from acme-client which does not support either of those capabilities to acme.sh which does. Since then external clients checking their email has not worked. A manual telnet to mail.example.com 993 gives a connected message but then nothing no greeting or capabilities. The certificate is for example.com with an alt name of *.example.com if that's not right let me know, i'm not sure about that one, connecting to the web sites of these pages seems noticeably slower, I'm wondering if both of these issues aren't key related? Thanks. Dave.

mdbox_deleted proper syntax
by Johan Huldtgren 31 Jul '18

31 Jul '18

hello, on the wiki, https://wiki2.dovecot.org/MailboxFormat/dbox, it says that one can use either doveadm fetch or doveadm import, however I can find no correct syntax with fetch that'll actually work. Is the idea to simply override the mail_location with -o ? That seems to work for doveadm mailbox but not for doveadm fetch or search # doveadm -f table mailbox status -u johan all dovecot mailbox messages recent uidnext uidvalidity unseen highestmodseq vsize guid firstsaved dovecot 0 0 1 1362145026 0 1 164208086 64bd9f0003af305190040000b9256959 1471825482 # doveadm -f table -o "mail_location=mdbox_deleted:~/mdbox" mailbox status -u johan all dovecot mailbox messages recent uidnext uidvalidity unseen highestmodseq vsize guid firstsaved dovecot 0 0 1 0 0 1 0 ddb9421479f0595bf21b0100b9256959 18446744073709551615 # doveadm -f flow fetch -u johan size.virtual mailbox dovecot size.virtual=2869 size.virtual=2960 size.virtual=8023 size.virtual=6683 ... # # doveadm -f flow -o "mail_location=mdbox_deleted:~/mdbox" fetch -u johan size.virtual mailbox dovecot # # doveadm search -u johan mailbox dovecot subject "LMTP Log" 64bd9f0003af305190040000b9256959 8642 64bd9f0003af305190040000b9256959 21302 64bd9f0003af305190040000b9256959 21373 64bd9f0003af305190040000b9256959 21420 64bd9f0003af305190040000b9256959 21434 64bd9f0003af305190040000b9256959 21435 64bd9f0003af305190040000b9256959 21460 64bd9f0003af305190040000b9256959 21461 64bd9f0003af305190040000b9256959 21463 64bd9f0003af305190040000b9256959 23684 # doveadm -o "mail_location=mdbox_deleted:~/mdbox" search -u johan mailbox dovecot subject "LMTP Log" # What I'm really trying to accomplish is see if a mail which a user deleted still exists in mdbox_deleted, so I wanted to do a fetch / search to see and then try to copy / import that message back.

Doveadm protocol; dovecot v2.2.10
by David White 31 Jul '18

31 Jul '18

Hi there, Just wondering what is considered current best practice for managing dovecot? The options I see are: Doveadm binary Doveadm protocol via socket Doveadm http protocol I’m currently on v2.2.10 and it appears the doveadm protocol command set is limited to just the “mailbox” commands and the http protocol hasn’t been implemented. Is the doveadm http protocol still experimental in v2.3.2?

Restricting SSL/TLS protocol versions on Dovecot 2.2.22
by J Doe 30 Jul '18

30 Jul '18

Hello, I have a question regarding SSL/TLS settings for Dovecot version 2.2.22. In: 10-ssl.conf there are two parameters: ssl_protocols ssl_cipher_list ssl_protocols is commented with “SSL protocol to use” and ssl_cipher_list is commented with “SSL ciphers to use”. If I want to disable SSLv3, for example, do I need to use both parameters or will disabling SSLv3 ciphers in ssl_cipher_list do the same thing ? So is: ssl_cipher_list = !SSLv3 …equivalent to: ssl_protocols = !SSLv3 ssl_cipher_list = !SSLv3 Thanks, - J

[Dovecot] quota-status not working in distributed environment
by Benoit Panizzon 30 Jul '18

30 Jul '18

Hello List Quick overview of our set-up: Postfix / Dovecot (2.2.2.1) / MySQL Cluster on (at the moment) three Servers to create a HA environment where you could easily add additional servers as the demand or load grows. Circular dovecot replication is used so each server uses another one as replication partner and allowing one server to fail. Dovecot Proxy Feature being used, so we can use round-robin DNS and each server can forward the connecting user to the correct 'master' for his mailbox. So far, everything works as expected. Now we want to reject emails to 'full' mailboxes during SMTP to prevent backscatter and use the quota-status policy service from within postfix. That works fine, if the mailbox or it's replica is present on the machine where quota-status is called, but it fails if it's run on a machine where neither the mailbox or the replica is present. In our case, we get a correct SMTP 550 'Mailbox Full' Reject in two cases and a LMTP generated bounce in the later case. Also `doveadm quota get -u user(a)example.com` return the correct quota if run on the two machines which have the mailbox and it's copy locale, but return 0% used if run on the other machine. Is there a way to get quota-status to also use the proxy feature to request the quota information from the correct machine? Or is the postfix policy daemon call to the quota-status socket documented somewhere (it must be, but where?) so we could implement it from within the Milter? (we use the sendmail Milter API from postfix to filter spam and viruses, do sender/recipient rewriting, forward bounce matching, rate limmiting, login/IP statistics to block botnets abusing phished addresses and legal intercept stuff anyway) Kind regards Benoit Panizzon -- I m p r o W a r e A G - ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 07 CH-4133 Pratteln Fax +41 61 826 93 02 Schweiz Web http://www.imp.ch ______________________________________________________

[SOLR] Where is solr-schema.xml?
by Peter Nabbefeld 27 Jul '18

27 Jul '18

Hello, running dovecot 2.3.2.1 on Arch Linux, and installed solr 7.4.0. According to the wiki, there should be doc/solr-schema.xml, but I cannot find it. Tried "whereis dovecot": dovecot: /usr/bin/dovecot /usr/lib/dovecot /etc/dovecot /usr/include/dovecot /usr/share/dovecot /usr/share/man/man1/dovecot.1.gz But I cannot find any xml files using find /usr/{lib,share}/dovecot -name "*.xml" Kind regards Peter

Dovecot v.2.2.32 and I have configured two imap post-login scripts and it seems like after successfully login scripts are not closed (dovecot_node/imap imap-postlogin : multiple processes are running still) and after some times there are too many processes and the limit is reached (imap proces_limit 1500): 1) #!/bin/sh case $IP in 10.10.1[1-2][0-7].*) exec "$@" ;; 10.11.2.4[0-9]) exec "$@" ;; esac CHECK_USER=`PGPASSWORD="password" /usr/local/pg952/bin/psql -h 10.11.1.3 -q -t -U postfixuser -d mail -c "select imap_allowed from users where name = '$USER' LIMIT 1"` if [ $CHECK_USER == "t" ] ; then exec "$@" fi if [ $CHECK_USER == "f" ] ; then exit 0 fi 2) PGPASSWORD="password" /usr/local/pg952/bin/psql -U postfixuser -d mail2 -h 10.11.1.3 -c "select last_auth('$USER','$RIP2','1')" > /dev/null exec "$@" Regards, Jack
