Sieve logging?
by ＠lbutlr 13 Jun '19

13 Jun '19

I am trying to create some sieve scripts to filter my mailing lists and am wondering if sieve logs anywhere, and it so where? I don’t see anything in mail.log beyond lines like: dovecot: lda(kremels(a)kreme.com)<39790><hNchChSkAV1umwAAIdGjjQ>: sieve: msgid=<267D5D71-D99C-4790-8706-C1A92BCC9F97(a)kreme.com>: stored mail into mailbox ‘INBOX' Which doesn’t really tell me anything other than that the script failed. -- If the #2 pencil is the most popular, why is it still #2?

Regarding dovecot, all you need to do is following: <https://wiki.dovecot.org/LMTP> <https://wiki.dovecot.org/HowTo/PostfixDovecotLMTP> (if postfix is your MTA) <https://wiki.dovecot.org/LMTP/Exim> (if exim is your MTA) > And are there any downsides? Not that I’m aware of. Things remained the same as when I was using LDA but using LMTP over Dovecot’s LDA brings some advantages like better performances (no need to fire up new processes for deliveries) among others one. There were several threads on the list related to LDA vs LMTP, such as: <https://dovecot.org/pipermail/dovecot/2016-June/104670.html> <https://dovecot.org/list/dovecot/2013-July/091617.html> > What do I do about > > lda_mailbox_autocreate = yes > lda_mailbox_autosubscribe = yes > > ? They’re also used by LMTP so no need to worry when migrating from LDA to LMTP. You can check what LDA’s options are specifically also used by LMTP in examples/conf.d/15-lda.conf -- matt [at] lv223.org GPG key ID: 7D91A8CA

Migrated from maildir to sdbox: questions
by Ranbir 13 Jun '19

13 Jun '19

Hi Everyone, I migrated my maildir mailboxes to sdbox without any show stopping errors, but I did see this during the migration and now I'm also seeing it in the log: Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota I'm not quite sure why this is happening. Any ideas? I am using a "public" namespace for several mailboxes to share emails: # public namespace configuration namespace { type = public # the default separator for Maildir is ".", so that is what should be # used automatically. separator = . prefix = Public. location = maildir:/var/spool/mail/thesandhufamily.ca/public subscriptions = no } Under the "public" dir in the old maildir setup, I have folders configured for various mail accounts. For example: .Ads .Junk .Bills etc. These "users" are setup in a passwd file so that I can use a different mail storage location for them than the one they get from ldap (same as above). Using dsync to migrate my other mailboxes was easy, but I don't know how to migrate these public mailboxes. I looked through the wiki and didn't see anything about how to do it. Could someone explain how I can migrate the public mailboxes? -- Ranbir

Sieve to strip html from multipart messages
by ＠lbutlr 13 Jun '19

13 Jun '19

Is is possible (I’m sure it is, so how) to strip multipart messages that are HTML and text of the HTML portion and leave the bare text message without also stripping other parts (like images or attached files). Or also to take messages that are only HTML and strip the HTML and replace it with a plain text version? I used to do this a long time ago with procmail and lynx, but it was never reliable since procmail doesn’t really understand MIME.

Updating passwords
by ＠lbutlr 13 Jun '19

13 Jun '19

I created some new users in my MySQL database using postfoxadmin. The passwords looked correct in the database and show the right prefix {SHA256-CRYPT} but logins were failing, so I manually created new passwords from the command line: doveadm pw -s SHA256-CRYPT -p “a password" -u kremels(a)kreme.com {SHA256-CRYPT}$5$ZKsovTv0Ddc9k4… I then went into the postfix database and manually updated the password field in the database. update mailbox set password = '$5$ZKsovTv0Ddc9k4…' where username like 'kremels(a)kreme.com'; SOME of the accounts can now login, but not all. I get a debug line like: dovecot: auth-worker(26599): Debug: sql(kremels(a)kreme.com,xx.xx.xx.xx,<rnadomlookingstuff>): SHA256-CRYPT(a password) != '$5$ZKsovTv0Ddc9k4… -- 'They've given us the answers,' he [Carrot] said.

LMTP and Sieve with <prefix><recipient_delimiter><user>
by Paul Muster 11 Jun '19

11 Jun '19

Hi there, Dovecot's LMTP implementation and Pigeonhole Sieve already do support the <user><delimiter><suffix> format. RfC 5233, the Sieve subaddress extension, also offers <prefix><delimiter><user>. Could Docecot's LMTP and Pigeonhole be extended to that effect? Thanks & greetings, Paul

Potfix+Dovecot with dsync replication problem
by Zeljko Dokman 11 Jun '19

11 Jun '19

Hi all, I am in need of some help. Straggling to make something work, trying to configure postfix and dovecote imap server with dovecote replication. Can’t figure out what is wrong with my configuration. Replication is working only for vmail user account, I am getting this error on my secondary server for all other users… dovecot: doveadm: Fatal: setgid(4015(zdokman) from userdb lookup) failed with euid=5000(vmail), gid=5000(vmail), egid=5000(vmail): Operation not permitted (This binary should probably be called with process group set to 4015(zdokman) instead of 5000(vmail)) primary server reports this error: dovecot: doveadm(zdokman): Error: doveadm server disconnected before handshake: EOF dovecot: doveadm(zdokman): Error: sync: Disconnected from remote: EOF doveadm replicator status '*' username priority fast sync full sync success sync failed vmail none 01:58:13 02:05:25 01:58:13 - zdokman none 00:00:25 02:55:26 - y test none 00:01:00 21:48:13 - y doveadm sync * doveadm(root): Fatal: execvp(Maildir) failed: Permission denied dsync-local(root): Error: read(remote) failed: EOF (version not received) I am attaching my dovecot.conf main.cf and master.cf. I think my problem is with permissions but I can figure out how to workaround it. Best regards

Sql user and maildirs
by ＠lbutlr 10 Jun '19

10 Jun '19

For many years I had the following in my dovecot.conf: userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext default_fields = uid=vpopmail gid=vchkpw mail_location=/usr/local/virtual/%u/Maildir mail=maildir:/usr/local/virtual/%u/Maildir driver = sql } Recently, I started having quite a lot of errors on one MySQL account (used as a bcc backup account) along the lines of Fatal: Namespace '': Ambiguous mail location setting, don't know what to do with it: /usr/local/virtual/backup@domain/Maildir (try prefixing it with mbox: or maildir: Messages were sitting in the mail and were also getting dumped into /usr/local/virtual/backup@domain/new and I ended up running a fun little awk to move them into the right folders: grep -r "<backup+" . |awk -F: '{t=tolower($2); f=tolower($1); gsub(/@.*/, "/", t); sub(/<backup\+/, "../Maildir/", t); sub(/\.\//, "",f); cmd="mv " f" “t; system(cmd); }’ So I changed my doevecot.conf to: userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext default_fields = uid=vpopmail gid=vchkpw mail_location=maildir:/usr/local/virtual/%u/Maildir mail=maildir:/usr/local/virtual/%u/Maildir driver = sql } And the errors went away. So, no problem here to solve, but I am curious why I haven’t been having issues until quite recently? Was there a change or have I stumbled into something where it only looks like I’ve fixed the issue? In case it matters? # cat dovecot-sql.conf.ex [7:57] [/etc/dovecot] driver = mysql connect = host=localhost dbname=postfixusers user=dovecot password=x default_pass_scheme = SHA256-CRYPT password_query = select password FROM mailbox where username ='%u' user_query = select 89 as uid, 89 as gid, concat('/usr/local/virtual/', maildir, 'Maildir') as home FROM mailbox where username = '%u' The only ‘recent’ change I’ve made to my configuration was creating the Maildir/ subfolder for all the virtual users instead of using the ‘mailder’ from the sql table (that is, I added “, ‘Maildir’” to the concat, but that was quite awhile ago. I’m pretty sure I’d have noticed this before. Is that user_query as it should be or should I set concat('/usr/local/virtual/', maildir) as home and also set concat(‘maildir:/usr/local/virtual/', maildir, 'Maildir') as mail here rather than in the userdb block? -- K is for KATE who was struck by an axe L is for Leo who swallowed some tacks
