SIEVE: handling of lineending in fields
by Ingo Thierack 25 Jul '17

25 Jul '17

Hello, migrated von the mailserver from centos to alpine linux. Most parts are run well. dovecot 2.2.31 sieve: 0.4.19 But i fight with on behavior. I have an sieve script which pipes a few fields to an external script which send this data to an telegram-bot. the part of the sieve-script. if header :matches "Subject" "*" { set "subject" "${1}"; } if header :matches "from" "*" { set "from" "${1}"; } if header :matches "to" "*" { set "to" "${1}"; } foreverypart { if header :mime :type :is "Content-Type" "text" { extracttext :first 30 "msgcontent"; break; } } pipe :copy :try "notify.sh" [ "", "(${from})#${to}#${subject}", "\"${msgcontent}\"" ]; What i get now is an error about looks like encoding of the linefeeds. default: line 107: error: specified :args item `"test 4??"' is invalid. Here is sent a mail which contains in subject "test 4". or default: line 107: error: specified :args item `"?? ?? ??? ??? Oracle Magazine "' is invalid. Here is sent a mail which contains in subject "test 4". On centos this was never an problem. With alpine-linux this process is complete broken. Any hints, where to look and maybee fix thie behavior? Mybe its ab problem with the libmusl which used in alpine. Regards Ingo

last_logon SQL mapping
by viper 25 Jul '17

25 Jul '17

Hi I have been attempting to do a mapping on the last_logon plugin. I have been reading the documentation on mapping. is there any way to customise a little more and create a individual SQL query for each of the functions SELECT and UPDATE, my current SQL setup has the username and domain in separate tables and my user_query and password_query are concat which I do not believe can be defined in the dictionary map process, I was also wanting to use datatime as the saved field but it seems only the unix timestamp is used. If there is any way to create a fully custom query that can be executed I believe this would allow me to preform the action am looking for in the same manner as the user_query and password_query If anyone has any suggestions please let me know Regards Craig

Strange Error: Password data is not valid for scheme SHA256. Please help me resolve it.
by david.madman2＠vfemail.net 24 Jul '17

24 Jul '17

Hello, I am using version 2.2.31 (65cde28) on an Ubuntu 16.04 VPS. I am attempting to setup a mail server using a flat file system as an experiment. I am able to send e-mail from external domain names and the messages land in my /var/mail/vmail/domain/user/ directories. I am trying to setup Thunderbird as an MUA using the information I generated on my VPS namely the IMAP server, username(a)domain.com, password, and SMTP server. IMAP server - www.domain.com SMTP server - www.domain.com Username - created in /etc/postfix/virtual-mailbox-users.db and /etc/dovecot/passwd.db Password - created by dovadm pw -s SHA256 and entered (along with the username) in /etc/dovecot/passwd.db I enter this information into "new accounts" in Thunderbird and select STARTTLS with ports 143 (IMAP) and 587 (SMTP). (I have experimented with a variety of other combinations too). I click "Done" which transmits the information to the domain server to verify the details. My /var/log/mail.log shows: Jul 22 18:40:48 www dovecot: auth: Error: passwd-file(test(a)domain.com,46.xxx.xxx.xxx,<wZoHUuxU6IAu9j4y>): Password data is not valid for scheme SHA256: Input length isn't valid (0 instead of 32) Jul 22 18:41:00 www dovecot: message repeated 2 times: [ auth: Error: passwd-file(test(a)domain.com,46.xxx.xxx.xxx,<fGoHUuxU6IAu9j4y>): Password data is not valid for scheme SHA256: Input length isn't valid (0 instead of 32)] Jul 22 18:41:02 www dovecot: imap-login: Disconnected (auth failed, 3 attempts in 14 secs): user=<test(a)domain.com>, method=PLAIN, rip=46.xxx.xxx.xxx, lip=139.xxx.xxx.xxx, TLS, session=<fGoHUuxU6IAu9j4y> What does "Password data is not valid for scheme SHA256: Input length isn't valid (0 instead of 32)]" mean? I assume that there is some kind of a mismatch between the way I generated the password with doveadm and entered it in passwd.db and the way I entered the non-hashed password into the password field in the new account section of Thunderbird. Is there a way to resolve this issue? My dovecot -n is below. You will note that the passdb section does have the scheme as SHA256.

You are essentially writing your own backend by taking over authentication. You'll be accepting user/password inputs into your checkpassword executable, then use the LDAP API (or some other system that will do it for you) to authenticate. (You can Google around for code snippets.) You'll have direct control over all aspects of authentication (if/when/where/etc) that a generic backend can't provide. You can choose do implement using shell/PERL/etc script, or compile to executable from C sources. It's more work, but if you need to do everything on your wish list, I can't see any eaiser option. One of the drawbacks is that a working password depends on both time and source address, which will be adversely affect performance on a busy server as authentication data cannot be cached.

dovecot/pigeonhole and sogo

Hello, I have two systems one with dovecot 2.2.31/Pigeonhole 0.4.19 selfcompiled through the src.rpms from ghettoforge on a CentOS 6.9 server and a second system of SOGo (3.2.9, nightly) on CentOS 7. Everything worked together until I made the update to Dovecot 2.2.31 Pigeonhole 0.4.19. Since then I get an error message when I try to upload a sieve-script. SOGo shows a message popup that "the service is temporarily not available" and in the log file of Dovecot i get: > Jul 12 15:26:41 mail2 dovecot: managesieve-login: Disconnected (no auth attempts in 0 secs): user=<>, method=PLAIN, rip=192.168.1.138, lip=192.168.1.135, TLS: Disconnected, session=<25U/xB5U/KLCw8GK> > Jul 12 15:26:41 mail2 dovecot: auth: Debug: auth client connected (pid=12182) > Jul 12 15:26:41 mail2 dovecot: managesieve-login: Disconnected (no auth attempts in 0 secs): user=<>, method=PLAIN, rip=192.168.1.138, lip=192.168.1.135, TLS: Disconnected, session=<4zxBxB5U/qLCw8GK> > Jul 12 15:34:35 mail2 dovecot: auth: Debug: auth client connected (pid=12263) > Jul 12 15:34:35 mail2 dovecot: managesieve-login: Disconnected (no auth attempts in 0 secs): user=<>, method=PLAIN, rip=192.168.1.138, lip=192.168.1.135, TLS: Disconnected, session=<uiR64B5UDKPCw8GK> > Jul 12 15:34:35 mail2 dovecot: auth: Debug: auth client connected (pid=12264) > Jul 12 15:34:35 mail2 dovecot: managesieve-login: Disconnected (no auth attempts in 0 secs): user=<>, method=PLAIN, rip=192.168.1.138, lip=1192.168.1.135, TLS: Disconnected, session=<LeJ74B5UDqPCw8GK> Does this mean that managesieve-login doesn't get authentication data from SOGo? SOGo logs for this error: > S[0x7f368f2bab60]: "IMPLEMENTATION" "Dovecot Pigeonhole" > S[0x7f368f2bab60]: "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext" > S[0x7f368f2bab60]: "NOTIFY" "mailto" > S[0x7f368f2bab60]: "SASL" "PLAIN" > S[0x7f368f2bab60]: "VERSION" "1.0" > S[0x7f368f2bab60]: OK "Dovecot ready." > C: AUTHENTICATE "PLAIN" {%d+} > LOGIN:PASSWORD > > S[0x7f368f2bab60]: NO "Error in MANAGESIEVE command received by server." > C: AUTHENTICATE "PLAIN" {%d+} > LOGIN:PASSWORD Than I compiled Dovecot 2.2.31 together with Pigeonhole 0.4.18 and than everything works again as expected. I can upload and activate sieve-scripts from the SOGo webinterface. After that I tried to disable TLS for sieve with ssl = no in the 20-managesieve.conf: [...] protocol sieve { ssl = no [...] to capture the traffic between SOGo and Dovecot/Pigeonhole but then the managesieve-login process crashes: > Jul 12 16:28:32 mail2 dovecot: managesieve-login: Fatal: master: service(managesieve-login): child 12941 killed with signal 11 (core dumps disabled) [last ip=192.168.1.138] Why isn't it possible to disable TLS for sieve and what changes between Pigeonhole 0.4.19 and 0.4.18 could be responsible for the disharmony between SOGo and Pigeonhole. I looked for 'changes' but could not find any hints regarding this problem. Is there a chance to get both work together again? And is it possible to disable TLS for sieve or why crashes the managesieve-login daemon? Any help would be welcome. TIA Thomas Robers

Modify stored mail contents?
by Evan Martin 23 Jul '17

Is there a safe way to modify the contents of emails stored by Dovecot? I'll probably only want to change the message bodies, not the headers, if that matters. Looking for ways to do this both for existing emails and new emails as they are received (though anything that works for existing emails can probably just be run again for new emails.) My mail storage is currently mdbox, but I could migrate to another format if that helps.
