[Dovecot] dovecot security with IPv6
Hi Timo, hi all others! In fact, I've only read one person claiming that IPv6 support opens up "too many backdoors" [1], but anyway, as I intend to run just particular services, please give me your opinion if it's insecure to have a dovecot server, which is accessed through a public IPv6 address... (or note just shortly what else could give a firm ground to such claims...) [1] http://forums.gentoo.org/viewtopic-t-882557.html

If thats not a secret, what is the reason why you can't be sure of things with just attaching a trusted timestamp header for each mail? Someone could edit or delete those mails? Well, if you'd be using a LDA like maildrop, you could easily just call some bash script or direct command to make a new commit as your VCS provide... After each newly arrived message.

Can there be any other reason to use it than because someone could delete or change a mail without your knowledge? signature.asc Description: This is a digitally signed message part.

[Dovecot] Execute mailfilter after message move
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...

So, if I have some 50KB of mailfilter rules, which I want to divide across a tree of filter files, each of which can inherit variables from their includers, handle mailinglists, sometimes deliver copies to multiple maildirs, is there a reasonable chance I can do with sieve? signature.asc Description: This is a digitally signed message part.

[Dovecot] Conditionally use a sieve script with deliver?
I found a post in this list [0], which says sieve scripts can be used to deliver mail as read. However, can it be done somehow conditionally, I mean, with a direct or indirect switch for deliver? For a nonexistent example, it would be simply < | deliver -m path/to/maildir -r > or maybe an environment variable could be exported to deliver sieve and checked there? (Still not sure if sieve can replace maildrop in my case, however, using it with dovecot creates various problems with interoperability; but perhaps I can just add those imap4flags like "\\seen" myself to the message with maildrop and avoid mess with sieve at all?)

But maybe you could also post a short info on how should deliver be called? I read that "The Dovecot LDA, called deliver, is a local delivery agent which takes mail from an MTA and delivers it to a user's mailbox, while keeping Dovecot index files up to date." However in my case maildrop seems to be in the place of deliver. Would it work if maildrop had deliver called by xfilter with the options appended, then followed by "to /dev/null"? signature.asc Description: This is a digitally signed message part.

Well, that is weird to me as I didn't! No joke, I did again: Thunderbird 3.0; KMail 1.12.1 Using KDE 4.3.1 (KDE 4.3.1); dovecot-1.2.6; So: 1) create folder TOP with KMail, then create a subfolder sub, which results in: "TOP" and "TOP.sub" (both prepared as maildirs with cur,new,tmp and maildirfolder file); 2) create folder "TOP2" on the same fs level with Thunderbird, then create a subfolder "sub2" into it, which results in: "TOP2" prepared and containing "sub2" also prepared (prepared just like with KMail).

[Dovecot] How to create UTF encoded folders?
Hey, as I understand from post [1], system folders with UTF-8 chars in their names will only be available for use with Dovecot2 and I certainly look forward to that, but somehow I was short of info about the current use of UTF characters like ā, Ž etc. Should I just omit thinking about modified-UTF-7, avoid those characters for the time being and then with Dovecot2 create UTF-8 encoded folders with MUA and also on fs? Or there is something to know anyway? Please suggest as it would be a pity not to create folders with utf symbols...

[Dovecot] IMAP client dependence on dovecot mail storage fromat?
Hi, After setting up a maildir tree with :LAYOUT=fs and accessing it with KMail and Thunderbird, various mail client-specific problems appeared, but, as I didn't try with maildir++, I would like to confirm here: does that matter for an IMAP client much if I store mail on server as ":LAYOUT=fs" or maildir++? Can it see differences? I would like to think, that IMAP protocol should provide for all transactions in a standard way and its dovecot's/server's sole business how it stores mail locally. However... These results seem not very good: KMail: try creating a folder "sub" in "parrent" and you'll get "parrent.sub" along with "parrent" on server side. There, however, are no problems with Latvian unicode chars. Thunderbird: it can create a new folder in "parrent" as desired, but it can't display Latvian unicode chars (being such at server side) on client, while, if I try creating a new folder with Thunderbird with these chars, on server it will look somewhat like base64! So I'm really confused. All together these things are pretty frustrating, sure, but I'd like to understand whats the real problem here! signature.asc Description: This is a digitally signed message part.

The whole problem lies in a desire to use these two things in the same time: 1. maildrop filters file for all users messages (to place sent mail right); 2. store / access mails from mailserver, which is also a relayhost.

[Dovecot] id/permissions question
People, There is an imap client, which runs with user1 uid, but when its accessed to watch a maildir, whose (and its contents) ownership is user1:user1, this error occurs: dovecot: IMAP(user1): fchown(/path/user1/dovecot-uidlist.tmp, -1, 12(mail)) failed: Operation not permitted (egid=1000(user1), group based on /path/user1) dovecot.conf contains this line: mail_privileged_group = mail authentication happens through passwd-file, where for user1 its uid and gid are specified as in /etc/passwd and /etc/group.
