Of course Web is different, I agree one SU per virtual host, however there SU is really irrelevant to the users, its used only for things like suexec etc, where all auth and user activity etc is done via their VU details.

And this bug has probably existed for years, and this is the first time someone's noticed it. So I don't think it's such a huge deal for most people.

I don't see us being able to go to 2.0 until after it's been out of beta for a few months. I hate to see the 'current' branch being deprecated before we have a workable 'stable' alternative to upgrade to.

Here we go; no longer can you justify your position so now you attempt to change the focus of it, and/or attach the responders of your post. I stand by my assertion that a properly configured system basically runs itself. Software updates, etc do on occasion require direct intervention by the system maintainer; however, if I have to reconfigure the system on a daily basis it is more than obvious that I have failed to properly set it up to begin with. In virtually every case when a serious problem has arose on the system, it could be directly tied to the "PEBKC" principal. By the way, I have no knowledge of this "Rich" individual, nor do I give a F**K either. Obviously you are mesmerized by, and perhaps even sexually attacked to him, so I suggest that you consult him from now on when a problem arises. -- Jerry ✌ dovecot.u...@seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

Uh. You're now using /var/empty, while originally your mails were in
~/mail/? It sounds like you've just kept breaking your setup worse and
worse. Do you have your original configs backed up? I'd suggest starting
again from there.
Looking at the original mails, the only problem I see is:
> user_query = SELECT maildir, concat('/var/mail/',maildir) AS home, 125 AS
> uid, 125 AS gid FROM mailbox WHERE username = '%u' AND active = '1'
1) don't return "maildir", it's ignored.
2) The /var/mail/ base dir is most likely wrong, if /var/mail/%u
contained mboxes. So your mail directories exist somewhere else. Find
them. This is why relative home dirs are no longer allowed, who knows
where they are..

This is where the fault lies, ive fiddled till I got it working but I never
had to specify a writable unique home directory in the past, it just worked.
I create users via postfixadmin and tried to specify /var/mail/%u/ as the
unique directory but of course it complains that dir doesn't exist then.
I would have expected it to create it, itself. That would solve that issue.
I have done all sorts of work arounds now to continue operating without it
by using /var/empty and all that , but now my squirrelmail doesn't work like
it should anymore.

[Dovecot] dovecot 1.2.11/ thunderbird 3.1 - moving folders
Hello List, customers telled me problem when moving folders in thunderbird which i can confirm. Following setup on my side: dovecot 1.2.11 with mbox. Thunderbird 3.1 with ready mailaccount and "Server supports folders that contain sub-folders and messages" is disabled. i create folder1 for subfolders and in folder1 a folder2 for mails. Now i create folder3 on toplevel like just like folder1 for subfolders. Now i drag/dop folder2 to folder3. Thunderbird is moving this folder successful but in folder1/.imap i can still see a folder folder2 which is containing a dovecot.index.log At this point thunderbird shows error-message when i start to delete folder1. It tells: [CANNOT] Mailbox is'nt selectable: folder1. AND [NONEXISTENT] Directory folder1 is'nt empty, can't delete it. What to do now? Is error on my or thunderbirds side? Parts of my config needed? Thanks, Andre

[Dovecot] dovecot 2.0, imap-login killed with signal 11
Hello,
I have 2.0.beta6 (3156315704ef) on Solaris.
A user can login, if he makes logout imap-login will be killed with
signal 11.
I tried both:
passdb driver ldap and userdb driver ldap,
or
passdb driver shadow and userdb driver passwd.

Here you don't change any relative path, but change to base dir of your

I guess, the problem is in maildir, this is not absolute.

Your mysql query returns /var/mail/<> as home directory, where
Dovecot puts files.

But it (-n) will deliver (rather than reject) into the regular INBOX
if the folder for the extension does not exist?
I'm using Postfix, but with dovecot as a transport.
main.cf has:
virtual_transport = dovecot
master.cf has:
dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f
${sender} -d ${us...@${nexthop}
dovecot.conf has:
mail_location = maildir:/home/mail/%Ld/%Ln/mail
I wonder if that ${EXTENSION} works in master.cf. I guess I gotta go
back to Postfix for reading. I assumed this would be a Dovecot
problem.

Re: [Dovecot] address extension going into folder
With Postfix, I use
mailbox_command = DOVECOT_LDA -n -e -m "${EXTENSION}"
where DOVECOT_LDA is the path do dovecot's deliver. The -n switch prevents
creation of the IMAP folder.
See http://wiki.dovecot.org/LDA
[Dovecot] address extension going into folder
Is it possible with a simple config change to make address extensions, e.g. alice+sa...@example.com, go into a folder, e.g. .INBOX.sales, and do so ONLY if that folder already exists (and just go into INBOX if it does not exist)?

I find a system-user scheme more complicated only when there is not a one-to-one relationship between the system user base and the usernames in one domain. I tend to use a non-system-user scheme more, now, because of things like having different sets of users in different domains, where, if not now, possibly in the future, a LHS will conflict with a system user, meaning I have to map the relationships. In cases where there is one domain and LHS will be the same as the system user forever (about 3 to 5 years in internet time), I'll use system users (with role accounts either forwarded or as real system users, depending on need). Otherwise, the multi-domain, multi-user-set, all stored under one system user, scheme (that I don't like to call virtual because there is nothing virtual about it once you avoid thinking in terms of system users) works quite well. A hybrid, where one or more domains are designated for system users, could still coexist with the multi-domain scheme.

However, Noel, I firmly believe that there are OPs (SAs ?) that greatly exaggerate the degree of difficulty of their job. I guess we all like to feel we are indispensable.

That's one of the most ridiculous things I've seen todate. Do you seriously expect ISP admins that may have for instance, 16 front end SMTP servers, each processing around 1.4 million connects a day, and accepting around 900K msgs each a day, are going to seriously sift through each servers logs every day?

I'd agree--not a lot of skill required. Managing it afterward? That requires mail admin skills, regardless of virtual or system user accounts. It requires admin skills if the box is actually managed correctly that is. Anyone who isn't looking at mail logs or log summaries daily and taking action on any problems needing attention doesn't count as a mail OP. -- Stan

Hmm, I understood Rob's post arguing that almost every Unix daemon "just plainly works" with system users. And, IMO, this is true for both: MTA and Dovecot. The requirements are low, because you have system tools to create users, installed daemons are pre-packaged to use them. Install, and you are set. I do _not_ argue about security here. I really wonder why some distros still allow ssh-access by default for every user and some don't. Even a virtual-user based setup requires system users, so one cannot ignore uid related security either. I also don't argue about flexibility. Rob is talking about a newbie setup (IMHO) and I do agree to him. Once one got accustomed to the field of mail-related services, one can make decisions.

I agree, virtual users are not only easier to deal with, it gives you greater flexibility, but most importantly, better security. in the mid nineties I started pooling my own mail onto my own server using system users, yes, lazy %$$* i was :) By early 2000 I had not only my domain but several friends domains as well, a PITA to administer, as ever wanted change had to wait for me, I refused to run any of the scripts around that permitted user management as I felt none were secure and ended up having 'root', I then migrated to using sendmail front end to what we used at my employers, a qmail-vpopmail solution (IMHO having qmail exposed was and is, like having M$ exchange exposed), this made things easier they can add/delete do whatever to their own users, so more free time for me, infact I've not had to do anything for any of them since, except, add their new domains, but it was a painful task converting all of them from mbox to maildir, it took nigh on 15 hours. (incidently we also used dovecot for pop3 as well as imap inplace of vpopmails pop3, much saner solution.) (I wrote a script to convert from vpopmail structure to a better structure when we moved from that mess to postfix/dovecot/mysql a few years back, that conversion, including moving mail took all of 45 minutes, most of that was copying mail, in the early days I did not like nor trust postfix, but are with it today and wouldnt use anything else again, in case I change jobs I've always kept my converting script hehe) Hrmm., boy, so far OT now I'll finish... So, my recommendation, is to plan for what might be some day, rather than wait until that "someday" arrives. <>
