well, home folder in Dovecot != $HOME (or ~user), but user-specific 
besides the mail storage root folder:


https://wiki2.dovecot.org/VirtualUsers/Home

Dovecot however uses ~ as abbrevation for "home directory".

You need to set mail_home to something, return userdb_home from passdb,
or home from userdb. Even for virtual users.

That seems like lmtp is not doing variable expansion for user settings.
What version of dovecot are you running?

Aki


$ sudo jexec mail dovecot --version
2.2.32 (dfbe293d4)

Jeff

I tried to repeat this issue locally, and was not able to. Can you
provide full output of

doveconf -n

and

doveadm user j...@example.com

with both %h and ~/

Aki


Found that I had two sets of passdb and userdb entries due to one from 
local.conf and and another from conf.d/10-auth.conf including 
auth-system.conf.ext -- unfortunately that wasn't the source of the 
problems.


Turning on auth_debug=yes in local.conf and enabling LOG_DEBUG level 
output shows that, in contrast to the "working" configuration, it looks 
like my passwd-file configuration is returning "home=0" -- consistent with


"Error: Relative home directory paths not supported: 0"



    auth: Debug: passwd-file(jeff,n.n.n.n,): lookup: 
user=jeff file=/usr/local/etc/dovecot/users
    auth: Debug: client passdb out: OK    1    user=jeff User    
&:/home/jeff:/usr/sbin/nologin


    dovecot: auth: Debug: passwd-file(jeff,n.n.n.n,): 
lookup: user=jeff file=/usr/local/etc/dovecot/users
    dovecot: auth: Debug: master userdb out: USER    1234567890 jeff    
uid=x    gid=x    home=0 auth_token=verylongauthtoken



These were the clues needed -- While 
https://wiki2.dovecot.org/AuthDatabase/PasswdFile talked about using a 
FreeBSD master.passwd file as a passdb, it neglected to state that the 
Linux format and FreeBSD format are different.


Linux   -- user:password:uid:gid:(gecos):home:(shell):extra_fields
FreeBSD -- name:password:uid:gid:class:change:expire:gecos:home_dir:shell
--^

Login will succeed, but the home variable will be populated with the 
FreeBSD "change" which is often 0


Wiki page updated with details on how to use FreeBSD /etc/master.passwd 
extracts with passwd-file

Thanks for the info. But I was more after some real performance figures such as
LMTP deliveries per second, IMAP logins per second or number of concurrent
IMAP connections or mails FETCH/sec.

If I had lets say 10 nodes handling incoming SMTP and delivery to local
maildirs in parallel and independantly on a network storage and imapping this
from another independant 4 nodes, then building a not needed bottleneck by
shifting over the local delivery via director and LMTP to fewer nodes is just
braindead creation of high loads on few boxes.

And btw it scales perfectly because all that is needed if load increases is
up'ing additional nodes for SMTP/delivery or IMAP _which are all the same (of
two types)_.

The loadbalancer needed for this can be equally used for e.g. web, ftp and
other services. So there is absolutely no extra stuff needed for the mail
setup.

You are building such a complex system and then you think that creating 
director layer 
would be complex?

Just out of curiosity may I ask what size of an environment is this? As it's 
very hard for
me to believe that this would scale.

The problem with data caching would not be existant if dovecot used O_DIRECT
like proposed in the nfs (linux) docs.

 From nfs(5) manpage 

The NFS protocol is not designed to support true cluster file system cache
coherence without some type of application serialization. If absolute cache
coherence among clients is required, applications should use file locking.
Alternatively, applications can also open their files with the O_DIRECT flag
to disable data caching entirely. 

- end 

AFAIK no complex director stuff would be needed then, right?
The second sentence implies that using file locking should also be enough,
which dovecot does.

doveadm mailbox list -s Segmentation fault

Hey,

I'm getting Segmentation fault when doing "doveadm mailbox list -s -u
kristjan.eentsalu".
doveadm mailbox list -u kristjan.eentsalu works fine.
