[Dovecot] Out of Quota Causing "BYE Too many invalid IMAP commands."
by Timothy White 30 May '06

30 May '06

Doing some testing in Squirrelmail, with quotas, and basically opening a message, and saving it as a draft, over and over until I run at of quota. This is what I get when I try and save a message that is larger than the size left May 30 19:36:36 mafeking dovecot: IMAP(joeblogs): Disconnected: Too many invalid IMAP commands. and in SM ERROR: IMAP server closed the connection. Server responded:* BYE Too many invalid IMAP commands. I would expect something a little more user friendly in that situation. I haven't worked out how to debug the IMAP session in SM, or how to run an IMAP session with logging. I may get around to setting up debug in dovecot to see what happens. I'm running dovecot beta8. Any suggestions as to how to make it 'die' nicer? Thanks Tim -- Linux Counter user #273956

[Dovecot] Leave copy on server problem.
by Dario Ale 30 May '06

30 May '06

Hello, I am using Dovecot 0.99.14-r1 with mbox format. I have a problem with the option "Leave copy on server", the messages are duplicated. I tried many options but I can´t find the solution. The last test was: I modified in src/pop3/commands.c (function list_uids()) the folowing things: "... client_send_line(client, message == 0 ? "%u %u.%u" : "+OK %u %u.%u", mail->seq, client->uidvalidity, mail->uid); ..." by "... client_send_line(client, message == 0 ? "%u %08x%08x" : "+OK %u %08x%08x", mail->seq, mail->uid, client->uidvalidity); ..." then, I removed all index files so this were regenerated, I deleted popstate.dat, after with Mozilla Thunderbird I got the messages. popstate.dat was regenerated too, with the following information: this is the last lines: "... k 000000b14062ffdb 1148496134 k 000000b24062ffdb 1148496135 " After I send a new email and get messages, the last lines in popstate.dat was: "... k 000000b14062ffdb 1148496134 <-- no duplicated k 000000b34062ffdb 1148496827 <-- duplicated of k "000000b24062ffdb 1148496135" k 000000b44062ffdb 1148496828 <-- new " the new messaged arrived and the previous message was duplicated. This problem happens with OutLook Express too. Please, somebody can help me?? Thanks very much. pd: sorry by my english. -- Dario Ale (dario.a en telpin.com.ar)

[Dovecot] Migration problems from Courier-Imap
by Mattia Martinello 30 May '06

30 May '06

Hi, I'm migrating from Courier-Imap to Dovecot-Imapd and I have some problems.. I don't want to change the IMAP folders, so I wish to have Dovecot's compatibility with Courier's IMAP folders. In the Dovecot configuration I configured this: namespace private { separator = . prefix = INBOX. inbox = yes } Dovecot correctly shows me the INBOX folder, but doesn't show me the subfolders anymore... What can I do to solve this problem? Thank you very much and goodbye. Mattia.

[Dovecot] Effect of "login_process_per_connection = no"?
by Pete Slagle 29 May '06

29 May '06

Using dovecot version v1.0.beta8 on FreeBSD 6.1_RELEASE with login_process_per_connection = no in the dovecot.conf file, I still get a new imap process for each IMAP login. That is, if a single user logs in five times, five imap processes are created. The difference appears to be that with a "yes" setting each user login causes a new copy of the imap-login processes to be forked, which then creates the imap process for the connection and exits. With a "no" setting, one of the existing imap-login processes creates the imap process directly (and does not exit). I am understanding the effect of this control setting correctly? Are there other actions or implications? Pete

[Dovecot] Security hole with mboxes
by Timo Sirainen 29 May '06

29 May '06

Unfortunately we have our first problem that could really be counted as security hole. Giving "1 LIST .. *" IMAP command allows the user to see all files and directories under the mbox root's parent directory, so potentially you could see other users' mailbox names. Nothing can be done with them though, so it's not possible to read or modify them. There are also some other less than wanted behaviors that can be done with "." and ".." directories, such as "DELETE .." command can give errors. Also with maildir if you store indexes in different directory than mails this command can be used to delete the index files. Anyway I don't see any of these as security issues. Hopefully most people have their mail directory under user's home directory, so this would only list the home directory's contents. But if you do have users' mails stored in eg. under /var/mail/%u/ directory, giving that command would list everything under /var/mail, assuming that the process has permissions to do that (that's why you should be using different UIDs for users if possible). This affects 1.0 beta and 1.0 stable releases, but not 0.99.x. Fix is in http://dovecot.org/list/dovecot-cvs/2006-May/005563.html I'll also release 1.0 beta8 now. Thanks for Bill Boebel for noticing "DELETE .." doing weird things with maildir.

[Dovecot] Subfolder in Maildir
by Bart Braem 29 May '06

29 May '06

Hello, We have installed a brand new Dovecot because it seems very interesting as an IMAP server. We created a mailbox for a test user and we succeeded in copying some mails into it. However making subfolders does not work. The only folders we can create are in the root, next to the INBOX that is. We thought Maildir does support subfolders (as opposed to mbox), are we wrong here? Our Dovecot version is 1.0.b8_1. Bart

OE just immediately say error , what is also worrying is the Corrupted index message even though i am using POP3. any ideas what to look for. I might add a test box running FC3 and the same .conf works!

[Dovecot] setting default_mail_env - INBOX not seen?
by Noah 28 May '06

28 May '06

Hi there, I am trying to figure out hte Proper defualt_mail_env definition default_mail_env = mbox:%h/mail:INBOX=/usr/mail/%u (yes /usr/mail not /var/mail) Most users have their INBOX at /usr/mail/%u and some users have saved-folders and other mail folders in %h/mail *** right now i am unable to view my inbox. But I can view all the folders and contents of the %h/mail subdirs visible as separate folders. do I have this set up correctly? My IMAP client is unable to see my INBOX file. Cheers, Noah
