[Dovecot] IMAP Folders Don't Make Sense
by Carlos Williams 27 Feb '10

27 Feb '10

I noticed for some reason that I am missing an IMAP folder called 'Symantec' that was under my Inbox. I see all my other folders listed on my mail client except 'Symantec'. I then login to my mail server which runs Postfix / Dovecot & there I can see it: /home/cwilliams/Maildir [root@mail Maildir]# ls -la total 608 drwx------ 33 cwilliams it 4096 Feb 25 13:23 . drwx------ 5 cwilliams it 4096 Feb 23 13:24 .. drwx------ 2 cwilliams it 53248 Feb 25 13:22 cur -rw------- 1 cwilliams it 3048 Feb 25 12:42 dovecot.index -rw------- 1 cwilliams it 178176 Feb 25 13:22 dovecot.index.cache -rw------- 1 cwilliams it 54936 Feb 25 13:23 dovecot.index.log -rw------- 1 cwilliams it 131124 Feb 10 16:18 dovecot.index.log.2 -rw------- 1 cwilliams it 121 Jul 15 2009 dovecot-keywords -rw------- 1 cwilliams it 8190 Feb 25 13:13 dovecot-uidlist drwx------ 5 cwilliams it 4096 Feb 25 12:47 .Drafts drwx------ 2 cwilliams it 4096 Feb 25 13:27 .INBOX drwx------ 5 cwilliams it 4096 Feb 25 08:55 .INBOX.ClamAV drwx------ 5 cwilliams it 4096 Feb 25 08:54 .INBOX.Dell.Quotes drwx------ 5 cwilliams it 4096 Feb 25 08:54 .INBOX.Dell.Warranty drwx------ 5 cwilliams it 4096 Feb 25 08:55 .INBOX.IBM drwx------ 5 cwilliams it 4096 Oct 2 2008 .INBOX.Logs drwx------ 5 cwilliams it 4096 Feb 25 08:55 .INBOX.Red Hat drwx------ 5 cwilliams it 4096 Feb 23 09:26 .INBOX.Symantec drwx------ 2 cwilliams it 32768 Feb 25 13:13 new drwx------ 5 cwilliams it 4096 Feb 25 13:25 .Sent drwx------ 5 cwilliams it 4096 Feb 17 08:37 .Spam -rw------- 1 cwilliams it 393 Feb 23 10:23 subscriptions drwx------ 2 cwilliams it 4096 Feb 25 13:13 tmp drwx------ 5 cwilliams it 4096 Feb 25 13:22 .Trash As you can see above there is a .INBOX.Symantec directory and I can 'cd' into it and see all my messages: /home/cwilliams/Maildir/.INBOX.Symantec [root@mail .INBOX.Symantec]# ls -l total 280 drwx------ 2 cwilliams it 12288 Jan 21 17:39 cur -rw------- 1 cwilliams it 2352 Jan 21 17:39 dovecot.index -rw------- 1 cwilliams it 233472 Feb 22 08:17 dovecot.index.cache -rw------- 1 cwilliams it 8428 Feb 22 08:17 dovecot.index.log -rw------- 1 cwilliams it 41 Oct 12 09:50 dovecot-keywords -rw------- 1 cwilliams it 6665 Jan 21 17:39 dovecot-uidlist drwx------ 2 cwilliams it 4096 Oct 2 2008 new drwx------ 2 cwilliams it 4096 Jan 21 17:39 tmp However when I open Thunderbird & Webmail (both use IMAP), I see my Symantec folder under a 'Drafts' folder. When I try and click on the Symantec folder as a sub folder in 'Drafts', I get an error: "The mail server responded:Mailbox doesn't exist: Drafts.Symantec" So why does it show up there and why can't I see it normally with all my other IMAP folders under my Inbox. I am confused. Please help! Thanks!

[Dovecot] Little Help with Plugin
by Alex Baule 26 Feb '10

26 Feb '10

Hi everyone..... I Build a plugin to concat my body and header splited.... Its have 2 "versions". One is with the body without modifications. The second, is with the body with crypto, and this crypto increase a little the size of email. So, without crypto, works fine, but with crypto i got stuck in some modifications. Because the email is splited, to handle it, i made a copy from istream-concat.c, and in i_stream_concat_read i made this changes. Every place that have the i_stream_get_data i get the index from concat (if is the frist or second stream) and if is the second, (my body) the unsigned char *data is the return from my function. if(cstream->cur_idx == 1){ data = decrypt_data(cstream->cur_input, &data_size); }else{ data = i_stream_get_data(cstream->cur_input, &data_size); } In this part, i get the function i_stream_get_data and put in the function too, to get the data in the same way, but i dont return the (_stream->buffer + _stream->skip;), i put this in a unsigned char * too, and work with this variable. The size_r, with the _stream->pos - _stream->skip, i update it, with the new value get from my total length from the decrypted buffer. In resume, every (inside istream_concat_read and istream_concat_read_next ) i_stream_get_data(cstream->cur_input, &data_size); // (in istream_concat_read is "pos" variable) I change to if(cstream->cur_idx == 1){ data = decrypt_data(cstream->cur_input, &data_size); //(in istream_concat_read is "pos" variable) }else{ data = i_stream_get_data(cstream->cur_input, &data_size); //(in istream_concat_read is "pos" variable) } Setting the unsigned char *data, with my decrypted data and the pos or data_size, with the length of buffer data , decrypted. I Think there is Ok with this, and must be work, but i got some errors with this, when the Email is read to get them, the total length read is diferent from the W flag in header name. FETCH [] for mailbox INBOX UID 2 got too little data: 1351 vs 1352 FETCH [] for mailbox INBOX UID 1 got too little data: 1357 vs 1360 FETCH [] for mailbox INBOX UID 3 got too little data: 691 vs 1303 There is some variable or something that i forgot to update with this news values ? I use the Zlib plugin for exemple to do this. Tks Guys !!!

[Dovecot] Regarding: **OFF LIST** subject declaration
by Jerry 25 Feb '10

25 Feb '10

Seriously, I just have to ask this question. Why mark via the subject line a message as "OFF LIST" and then send it via the normal list framework. Doing so only insures that the message is actually "ON LIST" irregardless of what nomenclature is used in the subject line. If a message is truly supposed to be "OFF LIST", then why not send it directly to its intended recipient(s)? If, on the other hand, it is meant for general review by the groups members, then why mark it "OFF LIST" to begin with? I am aware of the prefix "OT" used in several forums; however, that is usually only used to thwart the moderator of the forum from banning the message or chastising the OP. Its use is of dubious success. -- Jerry gesbbb(a)yahoo.com |::::======= |::::======= |=========== |=========== | The course of true anything never does run smooth. Samuel Butler

[Dovecot] FTS cron script to force index updates
by Stan Hoeppner 25 Feb '10

25 Feb '10

From: http://wiki.dovecot.org/Plugins/FTS "You could also build a cronjob to index users' mailboxes once in a while (by selecting each mailbox and issuing a SEARCH TEXT xyzzyx command)." Has anyone written a script to perform the above? If not, how would I do this? Would I write a shell script to telnet to the IMAP port and then issue the commands? Can this be done with a bash script? Or would I need something more serious like a perl script? Thanks. -- Stan

[Dovecot] dovecot2 Beta2: different certs for imaps and pop3s
by Andreas Schulze 25 Feb '10

25 Feb '10

Hello, is it possible to use differnent ssl certs for pop3 and imap ? I like to have differnet dnsnames for pop3 an imap services configured at customers clients. I tried to configure ssl_key and ssl_cert inside a <protocol>-login {} section but this failed. Of course I know sslcerts containing multiple dnsnames. But this seemes not a real, clean solution to me.

You are conflating UI blocking with network blocking (download), probably because that's how TB does it. IMHO, when you open a mailbox, messages should fill in and be accessible immediately, ie as soon as the headers are downloaded. Beyond a screenful, the client should continue to download headers so that when you do scroll down, there is no delay. This is especially useful when you are on a slow link. You spend SO much time doing nothing, ie reading messages, while the client could be doing work for you, and then when you scroll you have to wait again? Also you have to adjust this behavior if server-side sorting is not available and the user wants something other than message order. If you're worried about "wasting" bandwidth, a valid concern, the client need only prefetch another screenful of messages at a time. If your client is configured to sync message bodies, it should go ahead and do that before you start actually reading them, so that you are not waiting on download. Apple Mail, for one, seems to implement things as I've described. Note I am in now way endorsing Apple Mail as a good IMAP client. -frank
