[Dovecot] Where'd the Mail Go?
by John Reddy 16 Oct '12

16 Oct '12

Hi; I ran this: echo "Hello me" | mail -s "Dovecot test" $USER then created a bash script: for mbox in /var/mail/$USER /var/spool/mail/$USER ~/mbox ~/mail/* ~/*; do grep -q "Dovecot test" $mbox && echo "mbox: $mbox" done grep -q "Dovecot test" ~/Maildir/new/* 2>/dev/null && echo "Maildir: ~/Maildir" and ran it but couldn't find where the mail went. I checked /var/mail/my_user_name and it wasn't there, either. How do I find it? TIA, John

[Dovecot] Advanced dovecot tricks - spam review/release
by Marc Perkel 16 Oct '12

16 Oct '12

Hi, I'm looking for some advice to do a really advanced trick with Dovecot. I'm not sure if this can be done. I need to describe first. I have a spam filtering company that does front end spam filtering. (Junk Email Filter) I want to add a system where I store a copy of spam on a server and make it available to the customer to review and maybe resent on false positives. I know I could do something simple where I deliver all spam to a domain account and make it available to an administrator. Then if it's a false positive they would drag the message to a "resend" folder. I'll have something the checks the folder one a minute to pick up and resend. However What would be very cool is delivering the spam to individual accounts. So a user who logs in individually can see their own spam. But the admin for the domain would be able to see all users. Maybe the users would appear as folders? Then a master account (me) would be able to log in and see all the domains as folders and the users as folders inside the domains? One thing I can do is deliver the spam to 3 different places so it's visible on all levels. I'm just wondering if anyone out there has any ideas about that. And I'll need an authentication system.

[Dovecot] [sieve] - counting headers

In some of my maildrop filters I have rules with weighted scoring[1], but only to count headers (for example to count "Received:" header) ie. all these rules are of form "/pattern/:h,1" Can dovecot sieve do this?

HELP! I have installed sendmail, dovecot, and squirrel mail. The squirrel mail portion of it works just fine, but I would like to have Mozilla Thunderbird as a client. Whenever I try and connect to the server it says "Thunderbird failed to find the settings for your email account." We do have an MX record in DNS pointing to our server. We are using Ubuntu 12.0.4.1, and have Dovecot 2.2.6 sendmail version 8.14.4-2ubuntu2 We are doing this for a class project and it is due by Tuesday 10/16/2012.. Thanks, Justin

[Dovecot] dsync ignores ssh-agent
by Mark Hills 13 Oct '12

13 Oct '12

I use IMAP over SSH, in pre-auth. I wanted to use dsync to offline mail to my laptop. dsync v2.1.10 would always ask for my SSH key/passphrase, ignoring ssh-agent. The culprit is the env_clean() in the stack below. Reading the source, I saw DOVECOT_PRESERVE_ENVS. When used as follows in my script it enables dsync to find my ssh-agent: export DOVECOT_PRESERVE_ENVS="SSH_AGENT_PID SSH_AUTH_SOCK" dsync mirror ssh imap.example.com /home/mark/opt/dovecot/bin/dsync and it now works without asking for password every time. I'm posting here so that anyone else googling for the same problem will hopefully find this, as I couldn't find anything about this in the docs. Also I'm interested in why dsync so aggressively cleans the environment; I tried a naive removal of env_clean() but this breaks basic functions. With this dsync is working very well for offline mail -- combined with alpine and a local exim for the outbound queue :) Thanks -- Mark Breakpoint 2, env_clean () at env-util.c:59 59 if (clearenv() < 0) (gdb) bt #0 env_clean () at env-util.c:59 #1 0xb7df10fc in master_service_env_clean () at master-service.c:454 #2 0xb7df26d4 in master_service_exec_config (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:103 #3 0xb7df29be in config_exec_fallback (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:153 #4 0xb7df2b65 in master_service_open_config (service=0x809e7d0, input=0xbffff7e4, path_r=0xbffff780, error_r=0xbffff7d8) at master-service-settings.c:206 #5 0xb7df3130 in master_service_settings_read (service=0x809e7d0, input=0xbffff7e4, output_r=0xbffff7dc, error_r=0xbffff7d8) at master-service-settings.c:345 #6 0x0805c672 in doveadm_read_settings () at doveadm.c:275 #7 0x0805c7d6 in main (argc=5, argv=0x809e1c0) at doveadm.c:342

[Dovecot] INBOX.INBOX.Sent causes problems in 2.0
by Christoph Bußenius 12 Oct '12

12 Oct '12

Hi, we have our namespace rooted at "INBOX.". Sometimes, users have folders like "INBOX.INBOX.Sent" or "INBOX.INBOX.INBOX.Sent". I do not know why these folders are created; I suspect it is due to buggy MUAs. If a mailbox like INBOX.INBOX.Sent exists, then in some cases Dovecot counts all messages in INBOX twice. This behavior can be demonstrated as follows: 1) Create a folder named "INBOX.INBOX.Sent" (using the IMAP CREATE command) 2) Save a message to "INBOX" (in my example the message is 7 MB) 3) dovecot-quota contains: priv/quota/storage 7129025 priv/quota/messages 1 4) doveadm quota recalc -u user1 5) Now dovecot-quota contains priv/quota/storage 14258050 priv/quota/messages 2 I.e. the user will experience that his quota fills up very fast. "doveadm -f flow fetch -u user1 'mailbox guid' ALL" prints: mailbox=INBOX guid=040ce73645177850497d000040c59ffc mailbox=INBOX guid=040ce73645177850497d000040c59ffc However, "doveadm -f flow fetch -u user1 'mailbox guid' mailbox INBOX" prints the message only once: mailbox=INBOX guid=040ce73645177850497d000040c59ffc How can we prevent this kind of confusion? What I'd like most is prevent the creation of these weird folders. Most MUAs have problems listing them properly, especially if both "INBOX.Sent" and "INBOX.INBOX.Sent" exist. Dovecot 2.1 does not seem to count anything twice.
