[Dovecot] Very Complex Master Password Challenge
by Marc Perkel 21 Apr '06

21 Apr '06

This might require adding some new code to Dovecot to pull this off. But it would be extremely powerful if I could get this to work. Here's the situation. Having a master password is great for helping users and doing tech support. But - suppose I'm hosting many domains and I want to create master passwords for each domain separately so that the owners of the domain can log in as any user within that domain? Here's the way I have things set up. I have a directory of passwd/shadow pairs for each domain as follows: /etc/vmail/passwd.domain1.com /etc/vmail/shadow.domain1.com /etc/vmail/passwd.domain2.com /etc/vmail/shadow.domain2.com Additionally I have a master domain used for management of the other domains. The master domain is an email account for each domain under the domain junkemailfilter.net. domain1.com(a)junkemailfilter.net domain2.com(a)junkemailfilter.net The password and shadow files are like the others: /etc/vmail/passwd.junkemailfilter.net /etc/vmail/shadow.junkemailfilter.net So - the idea is that the owners of the domain have access to the email accounts on junkemailfilter.net and what I'm hoping to do is that they can use this as the master password for their domain only. Example: domain1.com(a)junkemailfilter.net domain2.com(a)junkemailfilter.net I suppose that the master password feature needs another new feature to limit the scope of what it is allowed to be a master password for. Something perhaps like: passdb passwd-file { # Path for passwd-file args = /etc/vmail/shadow.junkemailfilter.net master = yes scope = *@%u } In the above example "%u" is the user part of the master password. So that that master user would be for example "domain1.com(a)junkemailfilter.net" and it would be the master password only for users of domain1.com and not domain2.com. So - if you can follow this - then you will see that this would be a really cool feature to have. And - I'm guessing that it might be easy to implement.

[Dovecot] okay, working, but not quite pretty...
by Chris Lea 21 Apr '06

21 Apr '06

Hi all. I got my previous problem fixed. Effective uid and gid fix in dovecot.conf file made it work. However, I'm still seeing this in my /var/log/dovecot.conf dovecot: 2006-04-13 21:09:00 Info: imap(chl(a)iaminla.com): Effective uid=1000, gid=1000 The uid and gid *should* both be 1009, and I can't for the life of me figure out how to configure that. I looked around the list and couldn't find the answer. Help a noob out please? I promise I'll write up a detailed howto for my debian + postfix + dovecot using static userdb's when I have it all working. :) -- --------------------------------------------------------------- "When moderate to highly intelligent people get bored, bad things happen." -- Ann Moreno (310) 709-4021 http://www.chrislea.com ---------------------------------------------------------------

[Dovecot] hard link between courierimapuiddb and dovecot-uidlist?
by Jeff Tucker 21 Apr '06

21 Apr '06

Hi, guys. I'm attempting to transition between Courier IMAP and Dovecot. I may not be able to transition all the courierimapuiddb files instantly or even transition all my servers at the same time. Ideally, it wouldn't matter. Users can login and get to a Courier IMAP machine or a Dovecot machine and read their email (all mounted via NFS). My question is: is there any reason I can't just do a hard link between courierimapuiddb and dovecot-uidlist? That way, I can transition users over to Dovecot at my leisure. And, if I need to, I can move back to Courier. The hard link is essentially free and lets me make sure these files stay synced. Thanks Jeff

[Dovecot] Beta 7 maildir++ "unlimited quota"
by Apps Lists 21 Apr '06

21 Apr '06

Hi. It looks like Beta 7 is treating a zero quota in maildirsize as a literal quota value. The maildir++ specification says a zero quota means unlimited. Steve

[Dovecot] UIDL documentation
by Mark E. Mallett 21 Apr '06

21 Apr '06

Hi, I see this in the 1.0-beta7 dovecot-example.conf file: # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu # Courier version 0 : %f # Courier version 1 : %u # Courier version 2 : %v-%u # Cyrus (<= 2.1.3) : %u # Cyrus (>= 2.1.4) : %v.%u # Older Dovecots : %v.%u # # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. # # NOTE: Nowadays this is required to be set explicitly, since the old # default was bad but it couldn't be changed without breaking existing # installations. %08Xu%08Xv will be the new default, so use it for new # installations. and on the wiki at http://wiki.dovecot.org/Migration there is this: By default Dovecot generates POP3 UIDs differently than UW-IMAP. If you want to preserve them, with 0.99.x you'll have to patch Dovecot. With 1.0-tests you can use: pop3_uidl_format = %08Xv%08Xu In the dovecot-example.conf file, it appears that the mentions of "%08Xu%08Xv" as being fail-safe and being the new default may be typos, since that format doesn't seem to come from anywhere. Should they not say "%08Xv%08Xu" ? (It'll still provide the same sort of unique value, only with the ends reversed; i.e. it should still work ok. But consistency and compatibility is nice.) mm

[Dovecot] unlink a directory
by Alfred Tuinman 21 Apr '06

21 Apr '06

Hi, Occasionally I get an error message in my dovecot log when, in evolution, I click on the inbox: dovecot: Apr 21 00:07:06 Error: imap(admin): unlink(/home/admin/.maildir/cur/1145393825.P23027Q0M159929.terminator.odyssey.nl:2,ST) failed: Is a directory Instead of the message being delivered as a file it appears to be written as a directory. Deleting those directories solves the error message from reappearing. Any ideas? I use FC5, dovecot-1.0-0.beta2.7, postfix-2.2.8-1.2, procmail-3.22-16.2.1 Regards, Alfred

[Dovecot] Permissions for Public Namespace?

Dear List, We've been following: http://wiki.dovecot.org/SharedFolders But all we can do is subscribe. Our users can't create folders, move e-mails into the top level folder etc. Am I not grasping the shared folders idea correctly? Thanks. -- Kind Regards, Gavin Henry. Managing Director.
