[Dovecot] Quick question...
by dovecot＠segel.com 26 Feb '09

26 Feb '09

Hi, Here's the scenario. I want to set up a mailbox so that when mail sent to the address is piped to a processing application, instead of going to a mailbox. One way I can do this is to set up a mailbox and then have an application that checks to see if there's mail and then processes it. (Old school Unix script) Is there a way to set it up with dovecot? (Cleaner solution) Thx -Mike

[Dovecot] exim4 + dovecot + SquirrelMail virtualhosted on Debian
by Tim Legg 25 Feb '09

25 Feb '09

Hello, I have a Debian machine that is virtual-hosting 6 domains with exim4. I finally got exim4 working well enough where I can send and receive mail using the mail command on my machine. I would eventually like to have SquirrelMail (which requires IMAP) working on my website. For whatever reason, exim4 doesn't seem to support IMAP. I found out that Dovecot is a prominent IMAP server. So I installed the most current Dovecot package (1.0.rc15) in Debian. Something is broken though... As I log into SquirrelMail, I get an error message "Error connecting to IMAP server: localhost. 111 : Connection refused". To investigate, I decided to telnet localhost on port 143 and found out that yes, the connection is in fact refused. So what do I need to do in order to have dovecot listen on port 143? Also, I noticed when I restart dovecot... debian:/etc/dovecot# /etc/init.d/dovecot restart Restarting mail server: dovecotError: Can't use mail executable /usr/lib/dovecot/imap: No such file or directory I hope this isn't a serious problem. Thanks Tim Legg

[Dovecot] imap SORT core dumps on beta1
by jsiegle＠psu.edu 25 Feb '09

25 Feb '09

Steps to reproduce: 0 login userid password 1 select myfavoritemailbox 2 sort (FROM) UTF-8 ALL I tested alpha5 and it works fine. Here is the trace of beta1. I see many adds in revision 8726(hg annotate mail-storage.c), but that line number(674) is very old. So it might be a local problem. Here is what dbx "where" says about what happened. mailbox_header_lookup_init(box = (nil), headers = 0x0ffffffffffff260), line 674 in "mail-storage.c" wanted_fields_get(box = (nil), sort_program = 0x0ffffffffffff3a0, wanted_fields_r = 0x0ffffffffffff308, headers_ctx_r = 0x0ffffffffffff310), line 518 in "imap-search.c" imap_search_start(ctx = 0x0000000110021c70, sargs = 0x00000001100848b8, sort_program = 0x0ffffffffffff3a0), line 536 in "imap-search.c" cmd_sort(cmd = 0x0000000110021b58), line 136 in "cmd-sort.c" client_command_input(cmd = 0x0000000110021b58), line 603 in "client.c" client_command_input(cmd = 0x0000000110021b58), line 652 in "client.c" client_handle_next_command(client = 0x00000001100216d0, remove_io_r = 0x0ffffffffffff621), line 693 in "client.c" unnamed block in client_handle_input(client = 0x00000001100216d0), line 703 in "client.c" client_handle_input(client = 0x00000001100216d0), line 703 in "client.c" client_input(client = 0x00000001100216d0), line 748 in "client.c" io_loop_handler_run(ioloop = 0x000000011001f850), line 203 in "ioloop-poll.c" io_loop_run(ioloop = 0x000000011001f850), line 338 in "ioloop.c" main(argc = 1, argv = 0x0ffffffffffff918, envp = 0x0ffffffffffff928), line 315 in "main.c" (dbx) quit Thanks, Jonathan

All fail but 777. ps -ef|grep exim shows that exim is run by user 101. A look into /etc/group reveals the user as libuuid. Debian-exim is user 103. Could this be what is causing my problems? How do I change what user exim is run as? -- Daniel

[Dovecot] Securing mailboxes and passwords
by Daniel Aleksandersen 25 Feb '09

25 Feb '09

Hi list I am just experimenting with seting up my own email server. I want some tips and hints on how to secure my setup to prevent unauthorised assess to my email. I have read through the wiki and have not found many tips. I hope to improve the wiki with tips gathered from the emailing list. :-) A basic measurement I could take right now would be to set more secure file premissions on my setup. My setup is based on http://wiki.dovecot.org/HowTo/VirtualhostingWithExim with a few addittions: fetchmail and exim4 deliver mail to my maildir and dovecot grants me access through imap. dovecot authenticates against /home/postmaster/passwd.digest and ./passwd.cram -- Daniel Aleksandersen <aleksandersen(a)runbox.no>

[Dovecot] Calling dovecot deliver from procmail
by Harry Lachanas 25 Feb '09

25 Feb '09

I came up with this trick That is Since my previous mail server had a bunch of complex procmail recipies and I am not sure that I can turn them into sieve scripts I am calling dovecot deliver to drop mail in it's final $DEFAULT destination. :0 | /some/path/dovecot/deliver in order to update the index, control files etc upon delivery time. So far in my "tests" it works. But I wonder if this is wise or not. Regards, Harry.

[Dovecot] Dovecot problem after last Debian sid update
by Paul Scott 25 Feb '09

25 Feb '09

Hi All, After upgrading dovecot for sid Thunderbird no longer displays the contents of any emails I have had a working IMAP setup for as much as a year even though I don't understand dovecot configuration well enough to know how I got it to go in the first place. Here is the output of dovecot -n # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-1-vserver-686 i686 Debian 5.0 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_location: ~/Maildir auth default: passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd TIA for any clues as what to do next.

[Dovecot] OT: Fixing Messages To Be RFC 2822 Compliant
by Neil 25 Feb '09

25 Feb '09

So....apparently I have some messages which are not RFC compliant sitting in my mailboxes (mostly older ones), and I have some software which is refusing to handle such messages. 1. Does anyone know of a nice way to verify that all my messages are compliant/find those that aren't? (I suppose I could use the existing failing software, but I was hoping for something a little more robust...) 2. Does anyone know of any tools that will do The Right Thing as far as fixing these messages are concerned? Googling didn't turn up much for me, but maybe I wasn't hitting the right terms ("RFC message repair", "fix email message", etc.). Thanks.
