[Dovecot] multiple passdbs and auth sockets
Hello,
I want to use different authentication arguments for smtp and imap/pop3.
In the dovecot list I found this:
http://www.dovecot.org/list/dovecot/2013-August/091960.html
I tried to follow these instructions but dovecot refuses to find the
auth executable:

[Dovecot] Selectively allow non-SSL connections based on userdb
Howdy Folks, I am considering transitioning our mail service over to SSL-only. As a transition mechanism, it would make sense to force all new accounts to use SSL, but still allow old accounts to go unencrypted until some transition date passes. I have done some extensive searching but could not figure a mechanism through which I could specify a setting for this in userdb or similar. Does anyone have any ideas that doesn’t involve a post-login script? Thanks, Trent

Ah, it’s configurable only in v2.2. In v2.1 it can only be changed by recompiling with configure --localstatedir=/somewhere

Well, it shoud work exactly the same way as with zlib plugin .. difficult to say what you’re doing differently without seeing the code. After decryption the mail will look exactly the same as before encryption, right? No added/removed pieces of data? That’s a requirement when using zlib-like code for this. BTW. In v2.2.9 there’s also mail-filter plugin where you can implement this encryption/decryption using an external script.
[Dovecot] [Dovecot 2.2.9] mail-filter plugin don't load
Hello, I'm trying to load the mail-filter plugin (dovecot-2.2.9) with the following option in 10-mail.conf : mail_plugins = $mail_plugins mail_filter But I've got the following error when restarting dovecot : dovecot: imap: Fatal: Plugin 'mail_filter' not found from directory /usr/local/lib/dovecot I reinstalled dovecot-2.2.9 from sources (freeBSD ports) but it did not install the mail-filter library in /usr/local/lib/dovecot Thank you for your help. - Stanislas SABATIER s.sabat...@pobox.com ---
[Dovecot] Plugin development - ostream and index cache size
Hi, I'm new to this list, so first thanks for the dovecot tool! So far, it has been great to work with. Currently, I'm developing a scrambler plugin for dovecot, that should stores the mails encrypted. To do that, I've created the scrambler_ostream and scrambler_istream that does the encryption and that I hook in the mail storage process. The scrambler_ostream is stacked on top of the output stream of the mail_save_context (mail_save_context->data.output) and the scrambler_istream is attached to the input stream when the virtual function istream_opened in the mail_private struct is called. Basically, the encrypt/decrypt works, but during the process the data size changes slightly. And when I'm doing a FETCH BINARY[] via imap, it results in the error... Cached message size smaller than expected (204 < 208) Error: Corrupted index cache file /home/.../mail/mailboxes/INBOX/dbox-Mails/dovecot.index.cache: Broken physical size for mail UID 1 My guess is, that the FETCH function tries to deliver the unencrypted cache version of the mail (204 bytes) and not the stored version (208 bytes). How can I make dovecot cache the output of my scrambler_ostream or at least disable this caching for testing? I've read already a lot of code, but I've found a hint yet. How does - for example - the zlib plugin handle this issue? I have read the code a couple of times, but still have no clue. Best regards, Philipp

[Dovecot] restricted dovecot conf
Hi all,
I have a simple but well running dovecot configuration attached below.
Now I want to change some things. What I need is an IMAP-Server which
restricts the user to the following:
- no folder createable
- no messages deleteable
How to get what I want?
My Version: Debian x86 Squeeze, Dovecot 1:1.2.15-7.
Many thanks in advance!
Goran

Indeed, it is much better to be held hostage of a huge corporation that does not care the less about your little business and that may change it's licensing schemes or drop features on which you depend every moment. :-) I know I'm simplyfing a lot, but if "competences lock-in" should be weighted in the choice, I think it is also fair to consider vendor lock-in. Cheers, Daniele

If a company ever needs to sack key members of its IT staff for any reason, or if it decides to sack them all and outsource IT administration to a consulting firm, having an all or mostly MS infrastructure makes this a no brainer. I'm not suggesting this is a possibility in your case, but that it's simply something that management considers. If they don't they're not doing their job. Management should never allow the company to be held hostage, have no options, due to being reliant on a single systems administrator and his/er unique knowledge of the infrastructure. Seamless client integration *with windows clients*. This is something you didn't mention but is vital for some organisations (like mine, where a tiny minority of administrative workers use windows). Allowing one microsoft service into your organisation is like inviting in a Trojan horse. It won't be long before somone else says "why don't we try sharepoint now that we get a bundled license" or something, not to mention the licensing nightmare "wait I think we need a CAL for every end user!" Consider it if you are already a microsoft shop, otherwise avoid it as you would a plague rat.

Thank you Steffen, I’ve passed this along to my hosting provider and hope they can figure out how to fix the problem. Best regards, Sonovo On 11. des. 2013, at 08:46, Steffen Kaiser wrote: >
