[Dovecot] dovecot-example.conf error with POP3 UIDL format?
by Shayne Hardesty 10 Nov '05

10 Nov '05

I just installed dovecot 1.0alpha4 on a very busy RHEL4 server with about 1300 users. So far so good, except for the dreaded duplicate emails in outlook for users who use POP3 and have "leave message on server" selected. After searching the archives I found that this is usually related to the UIDL format. The example in the .conf file is this: / # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu / Note that 'v' comes first, then 'u'.. But, right under it, is this: / # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. / In this example (and the next example just under it) 'u' comes first, then 'v'. So is the first example right, in that %08Xv%08Xu is compatible with UW ipop3d, but not outlook? Or is the UW ipop3d example a mistake? For what it's worth %08Xu%08Xv seems to have fixed my users' duplication problems. Shayne

I'm running dovecot 20051026 version on Redhat4. I tried to do a stress test. However dovecot dies after I login a few hundred users. I have some error messages in my mail log and am not sure if they are related to the problem.

So its one of the library or the compilation itself that cause the problem of access denied. Any idea??? Thanks

[Dovecot] Moving from mbox to maildir?
by Patrick 09 Nov '05

09 Nov '05

Hi all, New to the list. I have an updated FC4 box with Dovecot version 0.99.14.4.fc4. My mbox size is about 76 megs and growing rapidly because of several high-volume mailing lists I'm subscribed to. I have noticed that over time the performance of the Evoluion/Spamassassin/Dovecot combo deteriorates. Someone on the Fedora users list suggested I have a look at moving to a maildir setup. Reading the docs I can't really figure out what to. Does anyone have a suggestion how I can safely move my mbox setup to a maildir setup? Much appreciated! Regards, Patrick

[Dovecot] mysql dovecot 1.0alpha4
by Pierre Laplante 09 Nov '05

I try to authenticate using mysql and I always get access denied. I wrote a program in C that connect to the database and it work. I put the code within driver-mysql.c and it failed!!! My question is do you set up anything (SSL?) that could explain this failure. thanks. Here is the code MYSQL *h; h = mysql_init (NULL); if (h == NULL) { fprintf (stderr, "mysql_init() failed (probably out of memory)\n"); exit(1); } if (mysql_real_connect ( h, /* pointer to connection handler */ "localhost", /* host to connect to */ "lyra", /* user name */ "xxxxxxx", /* password */ "lyra", /* database to use */ 0, /* port (use default) */ NULL, /* socket (use default) */ 0) /* flags (none) */ == NULL) { fprintf (stderr, "mysql_real_connect() failed:\nError %u (%s)\n", mysql_errno (h), mysql_error (h)); exit (1); }

[Dovecot] Problem with different case logins
by Roberto Suarez Soto 09 Nov '05

09 Nov '05

Hi, we have a system (Debian sarge) that uses LDAP for user authentication, via pam. We also have virtual users by using a static userdb [1], using the directory structure /var/lib/dovecot/postoffice/%u (i.e., a directory under /var/lib/dovecot/postoffice with the name of the user). The directory /var/lib/dovecot/postoffice belongs to postoffice:mail. IMAP folders, indexes and stuff go here; normal mail goes into /var/mail/%u. We are using dovecot 1.0alpha3 (upgrading to alpha4 soon). Today we've found a grave problem. Let's suppose you have the login "mylogin.domain.com". If you instead use the login "MYLOGIN.domain.com", the authentication works anyway (which is Ok), but dovecot creates a new directory under /var/lib/dovecot/postoffice with the different case, i.e., /var/lib/dovecot/postoffice/MYLOGIN.domain.com (which is not Ok). Afterwards, you can only access this new folder if you use the login with the caps. A new file (we're using mbox) under /var/mail/ with the new name is also created, though I don't understand yet how. We're using Postfix as MTA, and it always delivers to the lower case name. I hope you can understand the problem. If an user logs with a name with just one letter changed from lower case to upper case, all his/her folders and mail will be seemingly gone. Is this a bug or a feature? If the latter, is it possible to change this behaviour, or at least work around it? Thanks in advance. -- Roberto Suarez Soto Allenta Consulting robe(a)allenta.com www.allenta.com
