Sieve rewrite headers?
by ＠lbutlr 14 Jun '19

14 Jun '19

I’ve bene looking for examples on how to do this, but so far am coming up short. I want to check certain messages for a reply-ro header and if it is present, rewrite it to X-Reply-To: and then add my own reply-to header. I don’t see anything in the various sieve examples I’ve found on altering the actual message. There is the editheader extension, but I failed to find documentation or examples on how to use it. It appears that I can add a header and delete a header (addheader deleteheader?) but not rewrite one. So something like if header “Reply-to: foo(a)bar.xn--tld-9o0a { addheader "X-Reply-To: foo(a)bar.xn--tld-9o0a deleteheader “Reply-To:” addheader "X-Reply-To: bar(a)foo.xn--tld-9o0a } ?? Do I need to delete the header or will the add header overwrite the one that is there? Also, how do people manage different sieve files? Just cat them all into the active one, or is there a mechanism to import/switch/load other files?

Re: Re: CASifying dovecot and webmail

Hi. I have been trying for a long time to roundcube but I have trouble doing it. It may therefore be necessary to manage the casification of dovecot. Something that is not easy right now with the operating system version that I use. I am working with a kali 2019, and I have compilation errors when running the make on pam_cas. Any help will be useful to me. Thank you Charlie Harper Best regards,

Re: Migrated from maildir to sdbox: questions

Hi Ranbir, i think youre just using the wrong quota backend. https://wiki2.dovecot.org/Quota You should switch from "quota = maildir...." to another one, like dict. Converting your Public mailbox you could try this ( no guarantee .. just guessing. make backup ! ): doveadm -o mail_location="maildir:/var/spool/mail/thesandhufamily.ca/public" sync sdbox:/target/folder Regards, Daniel > > 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.

Outlook renames Junk folder
by Cliff Hayes 13 Jun '19

13 Jun '19

Hello, Some versions of Outlook will randomly rename the Junk folder to Junk Email. This of course causes errors because Dovecot can no longer store junk. I go in to Outlook for each user and add another Junk folder, so now they have Junk and Junk Email. This fix action lasts a while until Outlook decides to do it again. Is there a way to tell Dovecot that if the Junk folder doesn't exist, try sending the email to Junk Email folder? Thanks in advance.

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 12 Jun '19

12 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. 'Perhaps we can find out what the questions should have been.' --Feet of Clay
