[Dovecot] Outlook + Outlook Express
by Andrew Gargan 29 Jul '05

29 Jul '05

Hi I am having problems with users accessing their maildir mail stores through dovecot I am working on version 0.99.11-1 (on fedora core) It seems to be when the email size is large (450KB +) The errors are (the server disconnected unexpectedly) Have turned on the three Outlook and Outlook Express workarounds I found but no luck. Have read through logs and looked for clues but am just getting no where ... All the linux boxes here seem to be able to handle things fine ... (kmail evolution etc.) Thunderbird is also giving me hassles when trying to pull large mail files. The server is a 2.8 P4 HT with 1024 MB RAM 200GB SATA RAID. +- 7 domains and +-1200 users. Squirrel Mail seems fine and users are using that to get around the problem for now but I really need the pop3 access working ... My MTA is postfix and I am using virtual mailboxes using mysql_lookups. I am also running MailScanner and ClamAV and SpamAssassin (using the hold queue method) Regards Andrew Andrew Gargan Developer Interface Media (PTY) Ltd. Tel: 011 507 3003

[Dovecot] Handling virtual domains
by Phillip Davis 28 Jul '05

28 Jul '05

Hello all, I'm Having a sticky problem, and Im pretty sure I've configured dovecot wrong, I just don't know what I'm doing wrong. I have a system running sendmail. I need to sue virtual domains, as several domains will be hosted on this box. I am using squirrelmail for webmail and it has a vlogin plugin that allows me to use virtual domains, and it is working correctly, so far as I can tell. If a user goes to their email domain via http://www.domain.com/webmail/ and logs in, it correctly converts their login from just user that they typed in to user(a)domain.com, and if another domain was domain2.com and they went to http://www.domain2.com/webmail it will send user(a)domain2.com to dovecot. This is where I think I'm doing it wrong. Dovecot seems to just try that username which doesnt exist to the local OS of course, its just user, not user(a)domain.com. I read the part about dovecot using the auth_passdb and auth_userdb but was really confused how it works. if I use those, does it expect sendmail to deliver mail for those virtual domains to a new path I have supplied? also do I have to create a new and separate login and password flat file for it to authenticate? if so, how do I configure sendmail to deliver only those specific mails from each separate user from different virtual domains to be delivered? I'm just trying out the virtual domain thing, and I'm definitely really really confused because it seems each piece of software I have running here wants to do it differently. any pointers, hits or help would greatly be appreciated. -- Phil Phil(a)daviszone.org

[Dovecot] Preventing IMAP folder removal?
by John R. Dennison 28 Jul '05

28 Jul '05

Is there a way to configure Dovecut (version: dovecot-stable) to prevent the removal of an IMAP folder? We are planning on rolling out the @Mail webmail client to our user base in the next few weeks. This package has an internal Spam folder that we use to deliver spam into to allow our users to get to both their main mailbox and also their spam repository in one location. We are a Maildir shop, so the folder appears as: '~username/Maildir/..Spam' We want to use a sym-link to point '..Spam' to a location on another filesystem. Our testing shows that dovecot will happily follow a sym-link properly and no badness occurs as a result. Our concern, however, is that a user will attempt to remove their Spam folder, which will break the symlink and the next time a spam message is delivered the folder will be re-created as a directory and will reside on the same filesystem as their Maildir. Preventing the removal of the folder would be the easiest solution. If such a restriction is not already present in dovecot, might something be added to allow admins to lock down removal of folders? If this question has already been asked and answered on the list I apologize - I did quickly browse some of the back list and did not see a reference to the topic, but I admit, I may have missed it. Thank you in advance, John -- "I'm sorry but our engineers do not have phones." As stated by a Network Solutions Customer Service representative when asked to be put through to an engineer.

[Dovecot] Index File Permissions - Perhaps feature Request
by Marc Perkel 27 Jul '05

27 Jul '05

Trying an experiment to put the index files on a different volume than the mailbox files The idea being that the mailbox files are in a limited space slow raid1 array and the index files are somewhere else that is fast and not backed up. I'm using a virtual file structure as follows: /vhome/%d/home/%n The index files are set to: /nobackup/indexes/%d/%n Upon startup it created the index files correctly making all the missing directories. But I have an issue with the permissions. The problem is that it works for the first user, but the second user will have a permission error on the /%d/ level because of the 700 permissions. So - I would like to specify that directories that are automatically created have 770 permissions instead of 700, and, that perhaps I might want to ser the group permissions to 660 instead of 600. This might make Dovecot more ready for shared mailboxes in the future.

[Dovecot] Small Feature Dovecot Should Have
by Marc Perkel 27 Jul '05

27 Jul '05

There should be a config command that allows you to change the default ".subscriptions" file to ".mailboxlist" for WU-IMAP compatibility. Yes - I can rename them all but it would be handy for testing purposes and it should be trivial to add this feature. I'm still someone who is going to convert soon, but still testing and waiting for stability.

[Dovecot] Supporting charsets
by Armando Soto Baeza 27 Jul '05

27 Jul '05

Hi there! We are trying to use support for japanese language, but when composing in squirrelmail or while resending either in squirrel or in Outlook, we do not get the right symbols. The server and client PCs have all the required software. Indeed, we receive japanese written messages and can display them well. The problem arises when we resend or compose a message. In the squirrel configuration, we found that our imap has to support the charsets we want to use. The question is, how can we add this to dovecot. We are using release 0.99.14-1 on GNU Debian 3.1 r0 (sarge) Any idea? Thanks for helping -- Alta tecnologia para la empresa mexicana
