dovecot - Dec 2005 - %d empty even though username has @domain

hello,

Sorry to jump straight in with a question, but I've searched the  
archive[0] and I'm pretty sure the answer's not there.

I'm using dovecot to replace courier imap, so authentication is by  
vpopmail and the Maildirs are stored in the usual domains/domain/user/ 
Maildir. Everything seems to work very well, and setting it up has  
been easy, so thank you very much for that.

I have only one problem left: %d is empty when interpolated into  
default_mail_env. I expect there's something obvious I'm doing wrong,  
but it's hard to tell because the wiki isn't always up to date (i'd
be happy to update the vpopmail sections once this is working):

Config has this [1]:

	default_mail_env = maildir:/home/vpopmail/domains/%d/%n/Maildir

and i log in over imaps with the account i'm using for testing:
	
	username: sysadmin at spanner.org
	password: ...

Authentication seems to work perfectly, but then the logs show:

dovecot: Dec 05 12:24:59 Info: imap(sysadmin): maildir: root=/home/ 
vpopmail/domains//sysadmin/Maildir, index=/home/vpopmail/domains// 
sysadmin/Maildir, control=, inbox
any suggestions, please?

thank you,

will

I'm not using vpopmail, but I don't think prefetch ist needed for it, so
you should probably remove it.

Will, Timo,

[CCed to Timo as he implemented a solution to a related problem].

Digging this up from the archives - I have the same problem and can't 
find the solution. However: I've traced the problem through my mail logs:

Mar 22 18:16:43 tg1 dovecot: auth(default): client in: AUTH     1 PLAIN 
service=IMAP    lip=xxx.xxx.35.122       rip=xxx.xxx.32.85 
resp=AGRhbkBhbHVtaW5hdGkubmV0AHBhc3Mx
Mar 22 18:16:43 tg1 dovecot: auth-worker(default): 
sql(dan at domain.net,xxx.xxx.32.85): query: SELECT username as user, 
password, mailenv as userdb_mail, uid as userdb_uid, gid as userdb_gid 
FROM users WHERE username = 'dan' AND domain = 'domain.net'
Mar 22 18:16:43 tg1 dovecot: auth-worker(default): 
auth(dan at domain.net,xxx.xxx.32.85): username changed dan at domain.net ->
dan
Mar 22 18:16:43 tg1 dovecot: auth(default): 
auth(dan at domain.net,xxx.xxx.32.85): username changed dan at domain.net ->
dan
Mar 22 18:16:43 tg1 dovecot: auth(default): client out: OK      1 user=dan
Mar 22 18:16:43 tg1 dovecot: auth(default): master in: REQUEST  1 24736   1


The line to look for says:

username changed dan at domain.net -> dan

After this point %d is empty which is a problem if you use it in any 
configuration settings (which I'm trying to do).

The login now works because I use the prefetch to fetch the mail and 
home directory informatin out of the database (rather than dynamically 
work it out) but there are some other settings (ie namespaces) where I 
wan to use %d.

Can anyone suggest how to maintain the information in %d?
Particularly why does it shorten the username to "dan"?
