DBMAIL error on SELECT

Hi, I recently upgraded my dbmail to 2.2.11 and decided to create a new
email account/mailbox to make sure everything is working correctly. I sent
myself an email and retrieved it via outlook using dbmail-imapd. Below is
the error I received in dbmail.err

The email displays correctly, but wondering why I'm getting this error. My
email accounts that existed before I upgrade don't cause this error. I
should also mention that I also converted database type from SQL_ASCII to
UTF8.

Thanks,

/var/log/dbmail.err

Re: DBMAIL error on SELECT [In reply to]

What database server and version are you using? This seems like an older
database not able to handle that query.

PostgreSQL 8.3 issue. They started to have tougher type casts. The
message explains that "You might need to add explicit type casts.". I
still don't have it, so I don't know exactly how to cast it. Maybe

OR k.messageblk::varchar ILIKE '%multipart/encrypted%'

would solve the problem, but you can't cast from bytea to varchar, at
least in 8.2. Asking on the PostgreSQL list should help, I'll do that.

Interesting, I got this answer from a PG dev:
************
There has *never* been a Postgres release that accepted bytea ILIKE
something. I'm not sure what you were really doing before, but that
wasn't it.
************
So, this is the query you posted stripped down:
SELECT k.messageblk FROM dbmail_messageblks k WHERE
k.messageblk ILIKE '%multipart/encrypted%';

He's right, that query doesn't work on PG 8.1 either.

How did you make dbmail run such a query? Looks like via a search, but I
guess that never worked and would be a bug then. So please, how can I
reproduce that query?

Re: DBMAIL error on SELECT [In reply to]

First I created a new user on dbmail with dbmail-user with the following
options (-a -s -w -p MD5-HASH). DBMAIL created the new user/mailbox
successfully.

Next, I created an IMAP mailbox using Outlook 2003 SP3. Connected to
dbmail-imapd. Outlook showed a single mailbox (Inbox). I sent an email to
the new mailbox. The error occurred when I selected the Inbox and the new
message.

That block is in mailbox_search() (and the query is essentially the same
in both master and dbmail_2_2) and is for a "text" search. So, in an
imap session, after SELECTing a folder, something like:

C->S: 37331 SEARCH TEXT "multipart/encrypted"

should trigger the dbmail-imapd bug.

(I chose multipart/encrypted only to be similar the the search the OP's
client made.)

I tried that in a 'dbmail-imapd -n -v' session and got the same error:

dbmail-imapd[10679]: Debug:[sql] dbpgsql.c,db_query(+273): [.SELECT

I don't know whether it is possible to do full text searches on a BYTEA
w/o retrieving the whole thing; perhaps one of the extensions might add
a function which can do it?

OK, this is a bug in dbmail, which can be fixed in PostgreSQL 8.3 and
up:
http://www.postgresql.org/docs/8.4/interactive/functions-string.html

I would have thought convert_from, possibly combined with convert,
would do it.
And this should really do the magic, but I'm on 8.1 today, will test on
8.3 soon.

Indeed, convert_from() can be used to coerce the messageblk to text,
but only if dbmail knows how the blk is encoded.

This query in psql does give me the header of a message sent to this
group:

,----
| select physmessage_id from dbmail_messageblks where is_header = 1
| and convert_from(messageblk,'SQL_ASCII') ~ 'dbmail-dev' limit 1;
`----

It is, however, as one might expect quite slow.

If one blindly uses 'SQL_ASCII', octets other than those from in /[\n\t -~]/
aka /\n\t\x20-\x7E/ seem to be output as C-style backslash escapes.
That may or may not be useful for imap search.

There is also the question of whether imap search is supposed to search
the over-the-wire format of the mail or the as-viewed-in-an-MUA format.
Ie, how imap search and mime are supposed to interact.

This query would get all of the mail which have 'dmail-dev' in their
bodies, ordered by physmessage_id. But it is wildly disk intensive,
as psql has to read through every messageblk in dbmail_messageblks.

,----
| select convert_from(messageblk,'SQL_ASCII') from dbmail_messageblks
| where physmessage_id in ( select physmessage_id
| from dbmail_messageblks
| where is_header=0 and
| convert_from(messageblk,'SQL_ASCII') ~ 'dbmail-dev' )
| order by physmessage_id, is_header desc;
`----

Generating an index of the output of convert_from(messageblk,'SQL_ASCII')
would be painful at best.

The RFC is very clear on that one:

Server implementations MAY exclude [MIME-IMB] body parts with
terminal content media types other than TEXT and MESSAGE from
consideration in SEARCH matching.

So we don't need to match base64 encoded data, etc.

Also consider this:

In all search keys that use strings, a message matches the key if
the string is a substring of the field. The matching is
case-insensitive.

We try to avoid regexp matching for (possibly) historical performance
reasons, hence the use of ILIKE.

No way around that without full text indexing.

Any chance to have FTI support? PostgreSQL 8.3 has that built-in AFAIK,
so it could be interesting. Dbmail could support it if the DB supports
it, I just don't know how much effort that would be. Maybe just a
configuration line, or auto-detection?

FTI would help searching greatly, however on MySQL the default is to
only index words 4 chars or longer. Thus it makes it unreliable when
searching for a small word of 3 chars or less. You can change it to
index 3 chars, which would probably be sufficient, but since this is a
global change on the whole database server and would require a restart,
not everyone would be able to use it (hosted databases). I am unsure of
SQLite FTI. I really can't see support of SQLite remaining beyond 2.4
because of the multi-server over a network requirement of 2.5 Hydra.

Do you know what PostgreSQL does in as far as what is indexed?

That's why I said it maybe should be configurable. There's always
somebody/something not wanting/supporting that feature, but it could
help those with the capabilities to use it.

> Do you know what PostgreSQL does in as far as what is indexed?

No. I just read on the pg-users ML that 8.3 has that, and we are on 8.4
already. So maybe support is even better there. But I never used it, not
having a program using it....

I don't think any database's own full text index will really do what we
want for IMAP. I'd love to bolt on Sphinx or something like it and have it
manage the search index out of band. http://www.sphinxsearch.com/

Supporting SQLite is a great feature; it's important to be able to
configure for a single shard and remain on a single host.

I'd rather investigate the viability of an external indexer like
lucene/solr, extending the earlier design work I did:

http://www.dbmail.org/dokuwiki/doku.php/bodysearch

I beg to differ here. SQLite kicks ass. One main use case for me for
developing hydra would be kinda like what Geo did a couple of years ago
when he donated the original sqlite driver: give each user his own
sqlite database.

But then again, our ideas of what hydra should be are not yet set in stone.

Dude, you read my mind again? (or did I read yours...)

I wasn't aware of sphinx. Cool. Despite my lucene reference, I'm *not* a
fan of java bloat, brrr.
