[Dovecot] eudora issue
by kent crispin 16 Nov '04

16 Nov '04

There seems to be a protocol mismatch between eudora and dovecot when using pop. The login interchange with, for example, mozilla, is as follows: MO: [connects] DC: +OK dovecot ready. MO: CAPA DC: +OK DC: CAPA DC: TOP DC: USER DC: UIDL DC: RESP-CODES DC: STLS DC: SASL PLAIN DC: . MO: USER yyy DC: +OK MO: PASS xxxxxxxx DC: +OK Logged in. But with eudora, with apparently equivalent configuration, the sequence is as follows: EU: [connects] DC: +OK dovecot ready. EU: CAPA DC: +OK DC: CAPA DC: TOP DC: USER DC: UIDL DC: RESP-CODES DC: STLS DC: SASL PLAIN DC: . EU: auth PLAIN AG1tcgBtaXN0bGV0b2U= DC: -ERR Unsupported authentication mechanism. At this point eudora reports an error back to the user, and the connection fails. Can anyone shed any light on this? Is it just that there is an incompatibility in how eudora and dovecot view the protocol? Or is there some configuration option I need to tweak to make things work? Thanks for any help.

[Dovecot] (mail_index_expunge): assertion failed: (!t->view->external) Is this a bug?
by Daniel 16 Nov '04

Hi I am getting this a lot. Is this a bug? (mail_index_expunge): assertion failed: (!t->view->external) can be fixed by deleting the /home/<user>/mail/.imap directory. It has happened a few times with me. Regards Daniel Rowe

[Dovecot] RE: dovecot and outlook express and large messages
by Daniel 16 Nov '04

16 Nov '04

Hi Dose dovecot have problem working on a eth0:1 alias type interfaces? I just wondering if this could be my problem? Dovecot would do the authentication correctly and send small email but as soon as any load was put on it like downloading a mail with a large attachment it would fail. All network traffic would stop. No errors in the logs. As soon as I move the service to listen on a non alias interface eth0 all works fine. Very strange. I have taken a good look at our server to check that is not anything. I'm pretty sure we are good. I have also rebooted the box to see if that would fixed it which it didn't. Regards Daniel

[Dovecot] dovecot with different POP3S / IMAPS Certs
by Vincent Jaussaud 15 Nov '04

15 Nov '04

Hi, I'm new to dovecot, but actually planning to switch a wide WU-IMAP/POP installation to dovecot. With WU-IMAP, a different certificate can be used by pop3s and imaps, allowing both server to be reachable through different hostnames,without SSL complaints on the client side; this is mostly used for scalability. I'm trying to do the same thing with dovecot; that is having dovecot using a different certificate for it's pop3s instance and imaps instance. Unfortunately, in dovecot configuration file, only one certificate can be set; used by both pop3s / imaps. Any idea of the best way to handle this ? Thanks !

[Dovecot] dovecot-auth leaves zombies
by Stefano Maffulli 15 Nov '04

15 Nov '04

Hi all, I have installed and configured dovecot on two different machines, so I don't have much experience with this server. One installation is giving me serious problems, that I have a hard time tracing. From the beginning: the machine is a debian mix (stable/unstable) dovecot 0.9.11, real users authenticated via pam_ldap/nss_ldap. It serves ~70 users, all of them using Outlook, Outlook Express and IMP. The system seems to work just fine for a while, but after a some time, some dovecot-auth zombies start appearing. I can't really understand who/what is causing them. The only thing I see in the logs are these lines, very sporadically, but I still couldn't trace when they happened. Nov 5 09:40:28 csv-mail-01 dovecot-auth: nss_ldap: reconnecting to LDAP server... Nov 5 09:40:28 csv-mail-01 dovecot-auth: nss_ldap: reconnected to LDAP server after 1 attempt(s) (BTW, also apache2 sends similar messages, I don't know if they are related) Nov 5 09:52:14 csv-mail-01 apache2: nss_ldap: reconnecting to LDAP server... Nov 5 09:52:14 csv-mail-01 apache2: nss_ldap: reconnected to LDAP server after 1 attempt(s) After a while dovecot stops authenticating and needs to be killed and restarted (/etc/init.d/dovecot stop takes some time to actually stop dovecot processes). Do you have any clue of what is going on and where I can investigate further? I would like to say 'it's Outlook's fault', but I really can't. Any hint appreciated. regards stef

matthias thnx a lot for your hint. We are 2 admins on this box and this makes things complicated. /home 's permissions where 705 and that's the reason for this.

What are the permissions of the / and /home directories? ls -lad /home -- can dovecot execute the / and /home directories? If these are drwx------ or similar, that might be the problem. Hope that helps. -- Matthias Andree

[Dovecot] make error
by Ken Woodward (IS) 12 Nov '04

Dear DINH and TIMO, Here are the last lines before the fatal error. It says that "set fnord ; amf=$2; \ " is the command that caused the error. Does this make any sense to you? "if test "$dot_seen" = "no"; then \ make "$target-am" || exit 1; \ fi; test -z "$fail" make: Fatal error: Command failed for target `all-recursive' Current working directory /r/downloads/dovecot-0.99.11/src *** Error code 1 The following command caused the error: set fnord ; amf=$2; \ dot_seen=no; \ target=`echo all-recursive | sed s/-recursive//`; \ list='src doc'; for subdir in $list; do \ echo "Making $target in $subdir"; \ if test "$subdir" = "."; then \ dot_seen=yes; \ local_target="$target-am"; \ else \ local_target="$target"; \ fi; \ (cd $subdir && make $local_target) \ || case "$amf" in *=*) exit 1;; *k*) fail=yes;; *) exit 1;; esac; \ done; \ if test "$dot_seen" = "no"; then \ make "$target-am" || exit 1; \ fi; test -z "$fail" make: Fatal error: Command failed for target `all-recursive' Current working directory /r/downloads/dovecot-0.99.11 *** Error code 1 make: Fatal error: Command failed for target `all-recursive-am' /r/downloads/dovecot-0.99.11>"\ ============================================================================ ============================= I can include my complete config.log which does complete with no indication of failure reported at the end, BUT, inside it does list fatal errors like: "configure:2802: gcc -o conftest -g -O2 conftest.c -lcposix >&5 ld: fatal: library -lcposix: not found ld: fatal: File processing errors.

Can anyone help with this? I get the following error when running "make". "configure" worked fine. I am installing the latest dovecot on a Solaris OS10 machine make: Fatal error: Command failed for target `all-recursive' **** Error code 1 Also could someone tell me if it is possible to search all the archives through the complete message bodies or are we limited to searching each month individually and only on the message subject? Thanks for any help, Sincerely, Ken
