Replacing email envelope
by jon.sp2＠wp.pl 30 Nov '18

30 Nov '18

Hi, Could you please advice how I can replace envelope of a message received on my server? Best would be using sieve. Simple case - email A(a)example.com receives message, which I'd like to repack into new envelope (I want to have control what values in the envelope will be there - from, to, replay-to et.c) and send to B(a)test.com . At first I wanted to use editheader extension, but it is not allowing me to modify From or To values as far as I can tell. Another idea was to use envelope, but I don't see any way of editing values. Only reading. Now, I am thinking of writing script and from sieve it will be passed there, where I'll do message parsing and send new message using mutt or something similar. Frankly speaking I suppose there is much better solution to that and I'd appreciate any advice on the topic. Thanks, Jon

rspamd / imapsieve script is not executed/called
by Michael Ludwig 30 Nov '18

30 Nov '18

Hi to all of you, as I am struggling around with this a week or so I'm afraid I have to ask for help here. The problem is sitting right in front of the computer, as most of the time. ;-) So let me explain: Dovecot is working properly for IMAP with LE certificates, so I thought it's time to continue with Christoph Haas tutorial primarily and other blogs and tutorials for setting up the server. Next part would be to get rspamd learning what mails the user puts into junk folder. I followed the tutorial, but it will not work. Also I tried to get into debug mode, but I feel that dovecot is not really logging too much. Server is freshly set up Ubuntu 18.04.1, latest patchlevel with packages mostly from Ubuntu sources, except rspamd, but this was added as ppa if my remembering is correct. This is what I get on syslog, whilst *.* is being put at /var/log/allmessages. ######################################### Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: INBOX/Junk: Mailbox opened because: UID move Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: imapsieve: mailbox INBOX/Junk: MOVE event Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: sieve: Pigeonhole version 0.4.21 (92477967) initializing Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: sieve: Sieve imapsieve plugin for Pigeonhole version 0.4.21 (92477967) loaded Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: sieve: Sieve Extprograms plugin for Pigeonhole version 0.4.21 (92477967) loaded Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: imapsieve: Static mailbox rule [1]: mailbox=`Junk' from=`*' causes=(COPY) => before=`file:/etc/dovecot/sieve/report-spam.sieve' after=(none) Nov 25 23:30:50 myserver dovecot: imap(info(a)mydomain.tld): Debug: imapsieve: Static mailbox rule [2]: mailbox=`*' from=`Junk' causes=(COPY) => before=`file:/etc/dovecot/sieve/report-ham.sieve' after=(none) ######################################### So as far as I can interpret there is absolutely no script called when I move a mail from inbox to junk folder in Thunderbird.

Best way of merging mbox files
by Marc Roos 30 Nov '18

30 Nov '18

When concatenating mbox files like described here https://xaizek.github.io/2013-03-30/merge-mbox-mailboxes/. You will end up with an 'unsorted' mbox file. Is this going to be a problem esspecially when they are large >2GB's and new emails will be written to it? The email client nicely sorts the message from folder A "foldera 5 last" as last, but of course the mbox is not like this. Is there a better solution for merging files? Having: A folder A with messages: From Subject Received Size test foldera 1 16:18 665 B test foldera 2 16:18 665 B test foldera 3 16:18 665 B test foldera 4 16:18 665 B test foldera 5 last 16:29 670 B A folder B with messages: From Subject Received Size test folderb 1 16:23 665 B test folderb 2 16:24 665 B test folderb 3 16:24 665 B test folderb 4 16:24 665 B test folderb 5 16:24 665 B [@ mail] cat .foldera .folderb > .folderc Getting a folder C with messages: From Subject Received Size test foldera 1 16:18 665 B test foldera 2 16:18 665 B test foldera 3 16:18 665 B test foldera 4 16:18 665 B Mail System Internal Data DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA 16:19 454 B test folderb 1 16:23 665 B test folderb 2 16:24 665 B test folderb 3 16:24 665 B test folderb 4 16:24 665 B test folderb 5 16:24 665 B test foldera 5 last 16:29 670 B

"merging" folders Sent-Items Sent-Messages Sent
by Marc Roos 29 Nov '18

29 Nov '18

I have a running server and would like to clean up a bit, and merge sent folders and trash folders etc. Is this best done via the mailbox alias plugin like mentioned here? Or is there a better way? I prefer to have one folder listed at the client, and not "Unfortunately it also means that some clients will download the same mails to local cache multiple times." https://wiki2.dovecot.org/Plugins/MailboxAlias dovecot-2.2.10-8.el7.x86_64 CentOS Linux release 7.5.1804 (Core)

Hi, i'm quite often getting this error: Error: fts_solr: Lookup failed: 414 URI Too Long Most web servers are limiting URI length to 8192 characters. Why not to use POST instead of GET when communicating with Solr? Solr is able to handle this ok, also see: https://dzone.com/articles/solr-select-query-get-vs-post azur

determine why mail clients download mails 2nd time
by Poliman - Serwis 29 Nov '18

29 Nov '18

I have strange problem. In last Friday I had a problem with dovecot. It didn't see directories with mailboxes in /var/vmail. Somehow it crashed because probably two things (a lot of this type of lines in mail.err file): *Nov 23 07:05:02 s1 dovecot: lda(poli(a)poli.li <poli(a)poli.li>): Error: User initialization failed: Initializing mail storage from mail_location setting failed: mkdir(/var/vmail/poli.li/poli/Maildir <http://poli.li/poli/Maildir>) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /var/vmail, dir owned by 0:0 mode=0755)* and maybe *Nov 12 09:27:59 s1 dovecot: imap(artur(a)firmastanaszek.pl <artur(a)firmastanaszek.pl>): Error: Corrupted index cache file /var/vmail/firmastanaszek.pl/artur/Maildir/dovecot.index.cache <http://firmastanaszek.pl/artur/Maildir/dovecot.index.cache>: Broken MIME parts for mail UID 559 in mailbox INBOX: Cached MIME parts don't match message during parsing: Cached header size mismatch (parts=)Nov 12 09:27:59 s1 dovecot: imap(artur(a)firmastanaszek.pl <artur(a)firmastanaszek.pl>): Error: unlink(/var/vmail/firmastanaszek.pl/artur/Maildir/dovecot.index.cache <http://firmastanaszek.pl/artur/Maildir/dovecot.index.cache>) failed: No such file or directory (in mail-cache.c:28)* and after this event probably all mailboxes download again all emails from 1.11 to 22.11. They were duplicated in mail clients. -- *Pozdrawiam / Best Regards* *Piotr Bracha*

Dovecot Version: 2.3.2.1 Hello Mailing List, We are having a random issue in a couple of our production servers, where one of the child processes randomly dies with an out of memory error (see below): Nov 26 11:58:17 config: Fatal: pool_system_malloc(8192): Out of memory Nov 26 11:58:17 pop3-login: Fatal: Error reading configuration: read(/var/run/dovecot/config) failed: EOF Nov 26 11:58:17 config: Fatal: master: service(config): child 29696 returned error 83 (Out of memory (service config { vsz_limit=2048 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) We only use dovecot for internal application POP3 mail access from a mailbox, and there is under 10 connecting applications. Have have gradually increased the vsz_limit from the default of 256mb up to 2GB now. Is there anything else that should/could be changed instead of continuing to through memory at it? # dovecot -n # 2.3.2.1 (0719df592): /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-862.11.6.el7.x86_64 x86_64 CentOS Linux release 7.5.1804 (Core) # Hostname: <Internal host name here, removed> doveconf: Warning: please set ssl_dh=</etc/dovecot/dh.pem doveconf: Warning: You can generate it with: dd if=/var/lib/dovecot/ssl-parameters.dat bs=1 skip=88 | openssl dhparam -inform der > /etc/dovecot/dh.pem auth_cache_size = 10 M auth_verbose = yes base_dir = /var/run/dovecot/ default_vsz_limit = 2 G instance_name = EMX Pop Mailstore listen = <Internal ethernet Name Here, removed> log_path = /var/log/dovecot-echo.log login_greeting = Pop3 MailServer Ready. login_trusted_networks = <IP Addresses Here, removed> mail_location = maildir:~/Maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = cache_key=%u driver = pam } protocols = pop3 ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it userdb { driver = passwd } verbose_ssl = yes Thanks, Kevin
