[Dovecot] Rewrite the mailbox copy functions works in imap but don't work in doveadm import command
by Alex Baule 22 Feb '11

22 Feb '11

Hi Timo !! I rewrite the copy function from mailbox (using a plugin) My rewrite is like this: static int emexis_antispam_copy(struct mail_save_context *ctx, struct mail *mail){ struct mailbox *box = ctx->transaction->box; union mailbox_module_context *zbox = EMEXIS_CONTEXT(box); struct mail_private *_mail = (struct mail_private *)mail; union mail_module_context *zmail = EMEXIS_MAIL_CONTEXT(_mail); struct istream *input; const char *headerFile; char *bodyFile; int fd; int increment; ......Do some stuffs and verifications OK.... // GETTING THE FILE TO READ SOME STUFF FROM HEADER. if (zmail->super.get_stream(mail, NULL, NULL, &input) >= 0){ i_warning("GET STREAM COPY OK..."); }else{ i_warning("GET STREAM COPY NOT OK..."); } // REALLY COPY EMAIL copyret = zbox->super.copy(ctx, mail); } OK, when i use the IMAP , using a client and copy a email, it's works fine. But, when i use a doveadm import command, the part "(zmail->super.get_stream(mail, NULL, NULL, &input) >= 0)" fails, with no error message, only a segfault.... doveadm[14980]: segfault at 9c ip b7698000 sp bf83d7d0 error 4 in libdovecot.so.0.0.0[b7663000+6d000] doveadm[14983]: segfault at 9c ip b7661000 sp bf9c9ee0 error 4 in libdovecot.so.0.0.0[b762c000+6d000] doveadm[14986]: segfault at 9c ip b75b3000 sp bfcd82e0 error 4 in libdovecot.so.0.0.0[b757e000+6d000] doveadm[14989]: segfault at 9c ip b7684000 sp bfa5d3c0 error 4 in libdovecot.so.0.0.0[b764f000+6d000] There is difference between imap using a client , and doveadm import command ? If have some difference, can i identify and do some workarround ? Tks Timo !!

Re: [Dovecot] Segmentation fault running doveadm import
by Maria Arrea 22 Feb '11

Some more info: I am running dovecot 2.0.9 on Red Hat Enterprise Linux 5 Another question I would like to ask: I run the command doveadm import as "entrega" user (see dovecot -n output in my previous mail ). If I run the command as root also segfaults, and garbage is restored (mails with binary data). If I run as "entrega" segfaults, but e-mails are correctly restored Regards Maria.

[Dovecot] Best way to migrate versions and machines
by Donny Brooks 21 Feb '11

21 Feb '11

We are looking to migrate from our current mail server running dovecot-1.2.11-3 to a new mail server running the latest dovecot (2.0.9?). So this would not only be a version change but also a machine change. We currently use Maildir for storing mail and would like to stay that way. Has anyone preformed such a feat and it worked? Looking for any input.

[Dovecot] Regenerating mdbox/sis
by dmiller＠amfes.com 21 Feb '11

21 Feb '11

It's apparent I have some level of corruption in my mailboxes - something to do with the combination of mdbox, sis, and zlib. I should note that I know I have a mix of compressed and raw messages - if that makes any difference in identifying the problems. I think I need to somehow regenerate the mailboxes with issues. Is there a suggestion for how to accomplish this? Should I perhaps use dsync to shift to a temporary mail location and then rename it back? If I DO use dsync in this manner, and I have zlib enabled - will this then compress all the messages in the new mail storage? -- Daniel

[Dovecot] IMAP flags not being committed properly?
by Janos Barbero 21 Feb '11

21 Feb '11

I'm afraid I can't give steps to reproduce this, but if someone's come across something like this, it might help me figure out what's going on. I run imapfilter/offlineimap to fetch mail from a gmail to a local maildir store, which I then access with alpine via dovecot (1.2.15). Here's the output of dovecot -n: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian squeeze/sid ext3 log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:/data/1/mail:LAYOUT=fs mbox_write_locks: fcntl dotlock mail_plugins: fts fts_squat auth default: passdb: driver: pam userdb: driver: passwd plugin: fts: squat Just recently, I went through a bunch of old unread messages, marking them as read (in alpine). When I selected all unseen messages in pine (;sn), 18 showed up. But the count was higher within Gmail even after an expunge and offlineimap sync. So I selected all seen messages (;s!n) and marked them all as seen (a*!n). This didn't take long (for a 30k message folder) but surprisingly enough came back with the notice that 15 messages were marked as seen, and sure enough, at the next offlineimap sync, flags were updated on 15 messages. So I didn't touch anything in gmail, everything went to the maildir through dovecot via alpine, and then back to gmail via offlineimap. Yet the select command obviously did not return all the matching messages. Anyone know what's going on? Thanks, Janos

[Dovecot] dsync problem: Error: Can't rename mailbox INBOX
by Jan Binder 20 Feb '11

20 Feb '11

Hi all, I'm running two debian machines with dovecot 2.0.9 autobuilds and would like to keep mails synchronized on both via dsync. Mails are kept in maildir on both sides. While syncing, dsync gives the following error: dsync-local(jan.binder): Error: Can't rename mailbox INBOX to INBOX_a432bf2eca595a4dba47000043b078f4: Renaming INBOX isn't supported. dsync-local(jan.binder): Error: Can't rename mailbox INBOX_e184273887675a4dcc5b00000c16d079 to INBOX: Target mailbox already exists Further diagnostic information: dsync command: dsync -D -v -f mirror ssh jan.binder(a)firefly.local dsync dovecot -n on firefly.local: # 2.0.9 (159605040ec0): /etc/dovecot/dovecot.conf # OS: Linux 2.6.37-trunk-686-bigmem i686 Debian wheezy/sid managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } dovecot -n on depth.local: # 2.0.9 (049a922c193c): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian wheezy/sid managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } Should this usage of dsync work in principle?

[Dovecot] Permission denied after dist-upgrade

Hello, after I have done a dist-upgrade to Squeeze, I got some nasty problem with my dovecot. When I try to establish a connection via IMAP, it doesn't react and writes the following into my logfile: 2011-02-16 15:23:49 imap-login: Info: Login: user=<thomas@XXX>, method=PLAIN, rip=84.130.16.134, lip=XX.XXX.XX.XXX, TLS 2011-02-16 14:23:49 dovecot: Fatal: chdir(/home/vmail/XXX/thomas/) failed: Permission denied (euid=5000(<unknown>) egid=5000(<unknown>) stat() failed: No such file or directory) 2011-02-16 15:23:49 dovecot: Error: child 14493 (imap) returned error 89 (Fatal failure) dovecot -n: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-xen-amd64 x86_64 Debian 6.0 ext3 log_path: /home/vmail/dovecot-info.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl_ca_file: /etc/ssl/certs/sub.class1.server.ca.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: vmail mail_uid: vmail mail_gid: vmail mail_location: maildir:/home/vmail/%d/%n/ mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 namespace: type: private separator: . prefix: INBOX. inbox: yes list: yes subscriptions: yes lda: log_path: /home/vmail/dovecot-deliver.log postmaster_address: postmaster@XXX auth_socket_path: /var/run/dovecot/auth-master global_script_path: /home/vmail/globalsieverc auth default: mechanisms: plain login passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail I tried to change privileges for /home/vmail/, didn't work. What makes me wonder is the <unknown>-label after euid=5000. Anyone an idea how to fix that problem? Thomas
