SoI had a hell of a time converting my qmail install to dovecot 2.0.5,
so I thought I'd pass on what I learned.
1. When using vpopmail, do not use " --disable-many-domains". If you
do, you'll need to recompile vpopmail without that setting and use the
script found at
http://qmailrocks.thibs.com/downloads/scripts/migrate-vpopmail-many-domains
to collapse the tables.
2. Switch to mysql authentication. The following snippet works well.
driver = mysql
connect = host=/var/run/mysqld/mysqld.sock user=vpopmail
password=YOURPASS dbname=vpopmail
default_pass_scheme = PLAIN
password_query = SELECT CONCAT(pw_name, '@', pw_domain) AS user,
pw_clear_passwd AS password FROM vpopmail WHERE pw_name = '%n' AND
pw_domain = '%d'
user_query = SELECT pw_dir as home, 1008 AS uid, 1003 AS gid FROM
vpopmail WHERE pw_name = '%n' AND pw_domain = '%d'
3. When integrating Sieve, vpopmail apparently needs to own auth-master
and authdb. (example available on request)
4. If coming from maildrop as the LDA, you can put the following in
your maildroprc to allow a gentler transition (or to keep maildrop's
ability to call external applications)
`test -r /usr/libexec/dovecot/deliver`
if ( $RETURNCODE == 0)
{
`test -r $HOME/$EXT/.sieve`
if ( $RETURNCODE == 0)
{
to "| /usr/libexec/dovecot/deliver -d $...@$user"
}
}
5. When completely switching, you can either replace the .qmail files
or use one of the following in qmail/control/defaultdelivery
|/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d $...@$user
|/var/qmail/bin/preline -f /usr/libexec/dovecot/deliver -d
${EXT/-...@$user -a $...@$user
--
This should allow a final conversion to vpopmail 5.5 (from 5.4.30) with
dovecot 2.0.x.. I haven't done that final step yet, but it should now work.
Anyhow, I hope this saves someone a few days of head scratching.
