Hi! On the latest versions (2.2.28, 2.2.29.x) we get crash on dovecot config parse. Error in config parser when checking namespace mailbox name. Reason: comma in mailbox name. Worked well in versions < 2.2.22. Do not know if it was working on 2.2.23-2.2.27, skipped this versions. Example: namespace inbox { mailbox "&BB4EQgQ,BEAEMAQyBDsENQQ9BD0ESwQ1-" { special_use = \Sent } } Error: # dovecot -n # 2.2.29.1 (e0b76e3): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.18 (29cc74d) doveconf: Panic: file config-parser.c: line 89 (config_add_type): assertion failed: (ret > 0) doveconf: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x9b89a) [0x7fa1f8cc789a] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7fa1f8cc81d2] -> /usr/lib64/dovecot/libdovecot.so.0(+0x2f81a) [0x7fa1f8c5b81a] -> /usr/bin/doveconf() [0x40b213] -> /usr/bin/doveconf(config_parser_apply_line+0x763) [0x40b983] -> /usr/bin/doveconf(config_parse_file+0x821) [0x40c351] -> /usr/bin/doveconf(main+0x255) [0x406845] -> /lib64/libc.so.6(__libc_start_main+0xfd) [0x7fa1f88b6d1d] -> /usr/bin/doveconf() [0x4051f9] doveconf: Error: managesieve-login: dump-capability process killed with signal 6 doveconf: Panic: file config-parser.c: line 89 (config_add_type): assertion failed: (ret > 0) doveconf: Error: Raw backtrace: /usr/lib64/dovecot/libdovecot.so.0(+0x9b89a) [0x7f6dfa20489a] -> /usr/lib64/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7f6dfa2051d2] -> /usr/lib64/dovecot/libdovecot.so.0(+0x2f81a) [0x7f6dfa19881a] -> /usr/bin/doveconf() [0x40b213] -> /usr/bin/doveconf(config_parser_apply_line+0x763) [0x40b983] -> /usr/bin/doveconf(config_parse_file+0x821) [0x40c351] -> /usr/bin/doveconf(main+0x255) [0x406845] -> /lib64/libc.so.6(__libc_start_main+0xfd) [0x7f6df9df3d1d] -> /usr/bin/doveconf() [0x4051f9] Info: &BB4EQgQ,BEAEMAQyBDsENQQ9BD0ESwQ1- - is a valid mailbox name for russian Outlook folder "Отправленные".

Hi, I am trying to determine the correct LDAP schema I need to use to have either mailLocation or mailboxPath available ? Should I be just adding this to one of my own custom objectClasses ? -- Dave

20 Apr '17

Hi, i am using dovecot-2.2.10-7.el7.x86_64 on centos-release-7-3.1611.el7.centos.x86_64. if i follow this tutorial https://delog.wordpress.com/2011/05/10/access-imap-server-from-the-command-… i can login to my server and successfully list the folders using tag LIST "" "*" * LIST (\HasNoChildren) "." INBOX tag OK List completed. no folders are listed using tag LIST / "*" tag OK List completed. when i request a folder listing using JavaMail it similarly sends the following command and no folders are listed a97 LIST / "*" a97 OK List completed. if i follow the tutorial again and use my gmail account instead of my dovecot installation i can successfully list folders using both methods tag LIST / "*" * LIST (\HasNoChildren) "/" "youtube" tag OK List completed. is there some way to make dovecot list folders when it receives the command LIST / "*" i note that in the listings my dovecot installation has "." in the middle and gmail has a "/"

JavaMail setFlags on readonly folder
by Gabriele Bulfon 20 Apr '17

20 Apr '17

Hi, I'm facing a strange issue using JavaMail, where Dovecot let me open "READ_WRITE" a folder with readonly ACLs (same happens on other imap servers), but then doesn't issue any error when if try to setFlags(...) on that folder. The result is that the code thinks the folder marked the messages (deleted, flagged, etc), while it actually did not. Just refreshing the folder from the java client, you get back your original messages as they were before the operation. Is there any known issue about this?

Using filter in an imapsieve script?
by Tobi 20 Apr '17

20 Apr '17

Hello list I currently have an issue with an imapsieve script on my dovecot server CentOS Linux release 7.3.1611 (Core) Dovecot 2.2.26.0 (23d1de6) Pigeonhole 2.2.26.0 The goal is to "fire" an imapsieve script upon mailclient saves message to sent folder I setup the following in 90-plugin.conf: plugin { sieve_plugins = sieve_imapsieve sieve_extprograms sieve_extensions = +vnd.dovecot.filter +vnd.dovecot.pipe +vnd.dovecot.execute sieve_filter_bin_dir = /etc/dovecot/sieve-filters sieve_pipe_bin_dir = /etc/dovecot/sieve-filters sieve_execute_bin_dir = /etc/dovecot/sieve-filters sieve_filter_exec_timeout = 10000 sieve_pipe_exec_timeout = 10000 sieve_execute_exec_timeout = 10000 imapsieve_mailbox1_name = Sent imapsieve_mailbox1_causes = COPY APPEND imapsieve_mailbox1_before = file:/home/vmail/domain/user/dovecot-crypt-sent.sieve } and the content of the sieve script is: require ["environment", "vnd.dovecot.filter", "variables", "imapsieve", "vnd.dovecot.pipe", "vnd.dovecot.execute"]; if anyof (environment :is "imap.cause" "APPEND", environment :is "imap.cause" "COPY") { filter "gpgit" "myuser(a)mydomain.tld"; } gpgit is a perl script that encrypts a given message using the users pub key and returns back the encrypted message As a sieve script for lmtp/lda it works fine and encrypted messages show up in the mailbox. But it does not work if it is used as imap sieve script There is nothing in the logs that indicates a problem with the imap sieve script. Is it possible that 'filter' is not supported for imapsieve as it changes the content of a message? Thanks for any hint tobi

RSA key not found
by Michael Segel 20 Apr '17

20 Apr '17

I’ve got a couple of issues with a new mail server set up… I’m getting the following error: warning: cannot get RSA certificate from file /etc/pki/dovecot/certs/<mycert>.pem: disabling TLS support The problem is that <mycert>.pem isn’t an RSA ticket, but a X509 certificate. The RSA ticket is in /etc/pki/dovecot/private directory. I checked both files and they are good certificates. I’m using webmin to manage my server. In webmin, the TLS certificate file is the X509 and the private key is the RSA file. So why does Postfix check the certificate link for the RSA file and not the X509? Thx -Mike

Adding secure POP3?
by ＠lbutlr 20 Apr '17

20 Apr '17

I have a working server that only allows connections over secure IMAP (port 993) and secured submission (587). However, I have one account that has been forwarding mail to gmail for many years and that is getting to be more and more of a problem as more large sites enforce DMARC. So, the only way that gmail will pull mail is via pop3, so I need to add pop3 access. 1) How do I add a secure (TLS) POP3 service to dovecot 2) can I restrict access to that to specific users? Domains? OT, but someone probably knows, is secured POP3 going to work with gmail? ===BEGIN passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } ===END I did read <https://wiki.dovecot.org/SSL/DovecotConfiguration> but it’s about adding ssl to an existing setup. -- Apple broke AppleScripting signatures in Mail.app, so no random signatures.

my domain in both my destination and virtual_mailbox_domains?
by Michael Segel 20 Apr '17

20 Apr '17

I’m doing a new dovecot mail server for my domain. Here’s yet another thing I mucked up. I wanted to set up virtual mailboxes. One reason was that I wanted to set up virtual users for the domain so I don’t need to create user accounts just mail accounts. I followed one of the many examples / tutorials out there and I end up with the following warning message. postfix/trivial-rewrite[8818]: warning: do not list domain <machine>.<domain>.com in BOTH mydestination and virtual_mailbox_domains I checked my configuration, I don’t see where I’ve set up anything for mydestination in postfix. I’m trying to work thru the log file issues that I can find… this is just one more. To add to the confusion, I’m using webmin as my server admin UI to make life easier… yet it seems to much things up a bit Any suggestions? Thx -Mike
