The last change I made was to out uncomment pop3_uidl_format as I was suggested yesterday. Regards,

[Dovecot] a bug in the LDAP code
by Udo Rader 08 Jun '06

08 Jun '06

Hi, I was heaving some grave problems with dovecot's ldap client that left me with the following settings for virtual users: -------CUT------- mbox: data=/virtual/oeush.at/home/f.someone/mail/:INBOX=/var/mail/f.someone.oeush.at -------CUT------- data in that case was correct, yet the INBOX location was wrong, this should have been /virtual/oeush.at/var/mail/f.someone.oeush.at instead. My settings for the retrieval of the mail environment in /etc/dovecot/dovecot-ldap.conf were like this: -------CUT------- user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,MailMessageStore=mail -------CUT------- now at first glance this seems correct, but the problem was the upper cased "MailMessageStore" attribute name. changing it to "mailMessageStore" gave me the correct settings: -------CUT------- mbox: data=/virtual/oeush.at/home/f.someone/mail/:INBOX=/virtual/oeush.at/var/mail/f.someone.oeush.at -------CUT------- I don't have any of the LDAP RFCs ready, but I think that per default the case of the attribute _names_ should not matter when querying an ldap server.

Hi, I have a login issue. I do everything I can think of, but can't login. My .conf file is at http://kabuto.kunduz.org/dovecot.conf and I make slight changes everytime I try a new thing. I last set disable_plaintext_auth to yes and when I try to login using Thunderbird, I get *Code:* Sending of username did not succeed. Mail server mail.somedomain.org responded: Plaintext authentication disabled. , and dovecot.log reads *Code:* Info: pop3-login: Login failed: Plaintext authentication disabled: method=PLAIN, rip=212.98.201.1, lip=192.168.1.2. When I set disable_plaintext_auth to no and try again, I get *Code:* Sending of password did not succeed.

RE: [Dovecot] Using MySQL to store email?

Marc Perkel scribbled: > Repeat after me - think outside the box. Did you miss the part where I said we've already tried this? Not only have we thought outside the box, but we've smashed it up and built several alternatives to see which one sucked the least. Turns out, SQL backends suck the most. Please try to keep up :) Marc Perkel also scribbled: > To do this with MySQL would be trivial. To do it without a database > isn't possible. Actually you could do that with a tiny Sieve extension. I don't think you really understand what you are even proposing. Your statement would be better phrased "to do it without an index would be slow". If you wanted to create a database server for mail, with a mail-specific query language, then that database might be called "Dovecot", and the query language might be called "IMAP". Innovation is not an excuse for lousy engineering. As usual, it turns out to be bad design practice to say "let's deploy shinytoy for feature X!" rather than say "we need capability X! What's a creative way to achieve that?". Which is why necessity is the mother of invention. /JG

People who optimise their systems for shiny cute features rather than the common case get all the hacks they deserve. Repeat after me: design for the common case. Also your proposed sql above and implications (arbitrary operations based on mail metadata i.e. headers) seems to involve indexing every mail header on delivery. Good luck with that one large scale mail storage. Did you want a mail database, or an OLAP system? >-) /jg

Marc Perkel trolled: > So Timo, > > Have you considered the idea of storing all the email in a MySQL > database? Seems to me that MySQL could somplify all the backend stuff > that everyone struggles with and with replication one could create very > massive and reliable systems. What would it take to use MySQL that way? Maybe we could recode Dovecot in PHP, too. Sorry, that was nasty. However, having recently experimented with a very large mail storage system using mysql, I strongly advise against this avenue. In particular, the two main backends have serious deficiencies when you get up to the multi-gigabyte ranges: * MyISAM doesn't restart in constant time. * InnoDB's next-key locking kills performance on large blob inserts & deletes. Anyway, what do you mean, everyone struggles with backends? Dovecot's backends are fast, modular and reliable. Regarding replication; all good logical volume managers can do this. Regarding massive; all good filesystems can do this. Regarding reliable; I guarantee that mysql reliability (when properly managed) is still lower than that of a filesystem (when properly managed). In fact, the whole argument is specious. Filesystems already are databases, optimised for storing arbitrary-sized data objects using a hierarchical key, which is practically the definition of mail storage. /jg

[Dovecot] Dspam Plugin
by Timothy White 07 Jun '06

07 Jun '06

Johannes, do you have any plans (regarding your dspam plugin) to: a) Integrate it into libdspam rather than calling the dspam binary? b) Any ideas for scaling it better, and implementing it scaled better? I notice a slight discussion about scaling, and you have chosen not to pursue it. Is that because it's too hard, or just because you don't need to? Thanks Tim p.s. If I knew how to use the libdspam stuff, I'd make the changes myself... I might have to learn ;-) -- Linux Counter user #273956

I looked at the config.log file and it doesn't look like it's having any problems with openssl, but when I looked for pgsql I got what looked like some errors. configure:29296: checking for PQconnectdb in -lpq | char PQconnectdb (); | PQconnectdb (); ac_cv_lib_pq_PQconnectdb=no /usr/local/pgsql-8.1.4/lib/libpq.so: undefined reference to `dlerror' /usr/local/pgsql-8.1.4/lib/libpq.so: undefined reference to `dlclose' /usr/local/pgsql-8.1.4/lib/libpq.so: undefined reference to `dlopen' /usr/local/pgsql-8.1.4/lib/libpq.so: undefined reference to `dlsym'

Adding MySQL won't do that.
