Trying to install Mailcrypt, receive completely blank emails
by sewing 22 Aug '19

22 Aug '19

Hi - perhaps someone can help me. Starting from a good and well-functioning mailserver setup, I have installed MailCrypt as per the instructions (I think) to have the per-user passworded keys setup. dovecot.conf /Added:/ mail_attribute_dict = file:%h/Maildir/dovecot-attributes mail_plugins = $mail_plugins mail_crypt dovecot-sql.conf.ext /commented this/ #password_query = SELECT email as user, password FROM virtual_users WHERE email='%u'; /Added this/ password_query = SELECT \ email as user, password, \ '%w' AS userdb_mail_crypt_private_password \ FROM virtual_users WHERE email='%u'; 90-plugin.conf /Updated this section/ plugin { mail_crypt_curve = secp521r1 mail_crypt_save_version = 2 /Have also tried all configurations this option set /#mail_crypt_require_encrypted_user_key = yes } /The user is in the mailserver SQL database:/ | user | password | userdb_mail_crypt_private_password | +----------------------+------------------------------------------------------------------------------------------------------------+------------------------------------+ | user@domain | 4t63ttt36tttttt3rt6r763r76t8998t858t4y48ht4huu4hti.76876t847t47yt4ty478yt4wgwygfwffweggggggggggwy8yey83//FElgiApZU. | %w /I have reissued the keys as other problem resolutions have instructed to do, and I can see the new keys are active./ doveadm -o plugin/mail_crypt_private_password=(same password as user@domain when created in SQL) mailbox cryptokey generate -u user@domain -UR /I have restarted dovecot and postfix each time./ /I then send an email either from the user@domain > user@domain OR otheruser@otherdomain > user@domain from Outlook. Authentication is fine (POP and SMTP). No errors appear in any logs - the logs show the mail as being received and I can see the mail in the user@domain /cur folder. If I try to Postcat any of these messages I get:/ postcat '1*********2.M**********3.(host),S=633,W=649:2,S' *** ENVELOPE RECORDS 1*********2.M*********3.(host),S=633,W=649:2,S *** message_size: YPTED postcat: fatal: invalid size record: YPTED??? */Within a minute or so I receive the email in the Outlook Inbox - except it is completely empty of anything. There is no TO / FROM/ SUBJECT / Body or even Routing information. See screencaps from Outlook/* <http://dovecot.2317879.n4.nabble.com/file/t5785/message_list_view.jpg> <http://dovecot.2317879.n4.nabble.com/file/t5785/empty-emails.jpg> /This happens with existing user mailboxes and new test mailboxes I create. If I deactivate Mailcrypt all mailboxes/user-accounts work fine. Any ideas??? I would like to get the working - thanks in advance for your expertise and time!/ Graham -- Sent from: http://dovecot.2317879.n4.nabble.com/

imapsieve suddenly not working anymore
by Thomas Stein 21 Aug '19

21 Aug '19

Hello one and all. Dovecot version 2.3.7.1 I've configured imapsieve like https://wiki.dovecot.org/HowTo/AntispamWithSieve a while a go and it worked for years now. Suddenly i noticed moving mails to the spamfolder does not trigger the report-spam.sieve script anymore. sieve-test gives: ~/.maildir/.Spam/cur $ sieve-test /usr/share/dovecot/sieve/report-spam.sieve 1542388745.M99384P16720.meine-oma.de\,S\=8173\,W\=8373\:2\,S -D sieve-test(himbeere): Debug: sieve: Pigeonhole version 0.5.7.1 (db5c74be) initializing sieve-test(himbeere): Debug: sieve: include: sieve_global is not set; it is currently not possible to include `:global' scripts. sieve-test(himbeere): Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.5.7.1 (db5c74be) loaded sieve-test(himbeere): Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.5.7.1 (db5c74be) loaded debug: file storage: Using Sieve script path: /usr/share/dovecot/sieve/report-spam.sieve. debug: file script: Opened script `report-spam' from `/usr/share/dovecot/sieve/report-spam.sieve'. debug: Script binary /usr/share/dovecot/sieve/report-spam.svbin successfully loaded. debug: binary save: not saving binary /usr/share/dovecot/sieve/report-spam.svbin, because it is already stored. report-spam: error: the imapsieve extension cannot be used outside IMAP. sieve-test(himbeere): Info: final result: failed; resolved with successful implicit keep ~/.maildir/.Spam/cur $ I'm not sure the "the imapsieve extension cannot be used outside IMAP" is the error already or thats only because the sieve-test script. Any ideas on that? cheers, t.
