Only client knows, so only client may act. In that case, the only possibility is to have some automatic script that periodically "cleans" the "cur" subdirectories, as you suggested. However, not being a programmer at all, I'm far from being able to write an industrial-grade solution for this. ;-) Best regards, Răzvan

Re: [Dovecot] [RFE] A way to encode passwords in the /etc/imap.passwd file

@Pascal Volk Thanks for the algorithm you've provided ! Unfortuantely, I'm not a programmer myself and I don't feel confident to code such an utility (even if I perfectly understand your pseudocode). ;-) What I'm looking for is not even a hand-made script, but a production solution included in the stock dovecot RPM package itself - i.e a new, better form of the dovecotpw utility. Best regards, Răzvan

[Dovecot] Execute mailfilter after message move
by Kārlis Repsons 04 Feb '10

04 Feb '10

Hi, came here to ask, if there are any ideas about a possible Dovecot feature, which would allow execution of a specific mailfilter or other program after new message is *moved* in specified mail location? The practical benefit on my side would be, that there wouldn't be any need to do getmail cronjobs, which unnecessarily fill up logfiles... (primarily for easy spam learning and reporting)

[Dovecot] [dovecot] Problem with namespaces and dovecot -n
by Jonathan Siegle 03 Feb '10

03 Feb '10

I'm running dovecot 2.0 revision 10622:de9d6dae7fe5 on AIX. I'm trying to see both namespaces that I have listed in mail.conf. namespace private { separator = / prefix = inbox = no hidden = no location = maildir:%h/Maildir list = yes } namespace private { separator = / prefix = "#mbox/" location = mbox:%h:INBOX=/var/mail/%u inbox = yes hidden = no list = yes # for v1.1+ } Whichever namespace is last, I can see when running dovecot -n. Am I supposed to only see the last one printed? # 2.0.beta2: /usr/local/dovecot2.0beta2/etc/dovecot/dovecot.conf # OS: AIX 3 0001112AD300 auth_debug = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/krb5/dovecot.keytab auth_mechanisms = plain gssapi disable_plaintext_auth = no listen = * login_greeting = Dovecot version 2 on tr27n12 ready. mail_full_filesystem_access = yes mail_location = mbox:%h:INBOX=/var/spool/mail/%Ju/%u mbox_lazy_writes = no mbox_write_locks = fcntl mmap_disable = yes namespace { hidden = no inbox = yes list = yes location = mbox:%h:INBOX=/var/mail/%u prefix = #mbox/ separator = / name = private } passdb { deny = no driver = pam master = no pass = no } With this config I have no folders. If I flip the namespaces in the config, I have no INBOX and can't login. Thanks, Jonathan

[Dovecot] [RFE] A way to encode passwords in the /etc/imap.passwd file
by Răzvan Sandu 03 Feb '10

03 Feb '10

Hello, Is this the proper place to suggest an enhancement for the stock dovecot package ? The enhancement would be the following: For the time being, the dovecotpw utility offers a standardised way to interactively encode a user password in a certain scheme, say: dovecotpw -s CRYPT Enter new passord: Re-enter new password: etc. Given a *valid* /etc/imap.passwd file (passwd-file authentication), dovecotpw should be able to process it non-interactively and output another text file with all {PLAIN} passwords converted in the specified <scheme>, i.e.: dovecotpwd -s CRYPT if=/etc/imap.passwd of=/etc/imap.passwd.converted where /etc/imap.passwd.converted have the previously {PLAIN} passwords converted in scheme CRYPT. Passwords that were previously encrypted in other schemes than {PLAIN} shoud remain untouched. That will allow quick securing of old legacy /etc/imap.passwd files. Thanks a lot, Răzvan

[Dovecot] deny=yes in userdb
by Edgar Fuß 03 Feb '10

03 Feb '10

I would like deliver to reject certain users. Since supposedly deliver only uses userdb, not passwd, I can't use deny=yes for that. Or does userdb support deny=yes? Yes, I should rather reject them right in the MTA, but that currently takes too long to implement. Or how to reject gast* in postfix using nss authentication?

[Dovecot] Restore of individual mail files
by CoolAtt NNA 03 Feb '10

03 Feb '10

Hi. In order for restoration to work fine, I have to create a folder using the interface (e.g RounCube) which also creates the required structures. Then I copied the emailfile e.g xyz:s to /myrestoredemail/cur/ How do i properly create a folder with its structures(index,etc) without using the RoundCube web inteface ? Thanks CoolAtt _________________________________________________________________ Hotmail: Trusted email with powerful SPAM protection. https://signup.live.com/signup.aspx?id=60969

[Dovecot] disabling mail delivery for a user
by Frank Cusack 02 Feb '10

02 Feb '10

How can I disable mail delivery for a user yet still allow access to their mailbox from another account which their mail is shared to? If I put them in a userdb which has "deny = yes" that just disables their ability to login, yes? And they would still have mail delivered. I want to disable their ability to login AND bounce all mail delivered to them, preferably solely through dovecot configuration. I am using lda, obviously, for mail delivery. (I could configure the MTA to reject mail for them if there is no other option.)
