Hello,

on my private fully updated Fedora 34 system I've replaced version 2.3.16 by
version 2.3.17 without touching the configuration.

Whereas version 2.3.16 worked the new 2.3.17 says

Undefined SSL object

[Frank Elsner]

Hi community,

when doing imapsync to my dovecot server (Host2) I get the following

Host2 capability before authentication: IMAP4rev1 SASL-IR LOGIN-REFERRALS ID 
ENABLE IDLE LITERAL+ STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH
DEBUG: .../IO/Socket/SSL.pm:1117: global error: Undefined SSL object
Host2: Socket successfuly converted to SSL

Beside this message all works fine.
What is it? SSL setting? How to overcome the message?


Greetings, Frank

Quota: How/where to set/change

[Frank Elsner]

Hi experts.
in the output of imapsync I found:

Host2: found quota, presented in raw IMAP
Sending: 7 GETQUOTAROOT INBOX
Sent 22 bytes
Read:   * QUOTAROOT INBOX "User quota"
* QUOTA "User quota" (STORAGE 420325 1953125)
7 OK Getquotaroot completed (0.001 + 0.000 secs).

Host2: Quota current storage is 430412800 bytes. Limit is 20 bytes. So 
21.52 % full

Host2 is under my control and running dovecot-2.3.10.1.

I need to increase the quota above 2 GB but don't know where it comes from and 
therefor
don't know what to do.

This is the doveconf -a:

These messages disappear after changes in the auth and anvil config but I ran

I narrowed the probelem down to the warnings

Warning: service auth { client_limit=128 } is lower than required under max. 
load (768)
Warning: service anvil { client_limit=256 } is lower than required under max. 
load (643)

Where comes max. load from?

Bad idea. The user may already taken the action needed for infection. And what

In my country (Germany), information suppression would be punishable.

You should consider to switch off POP. POP is for people living in caves.

  Yes, it is a means to stop people from using insecure devices.
 
 a client certificate hadrly makes a device secure
 if the device is compromised your cert is gone
 
  So possibly a useful hint the OP may be interested in! Might well be that

 well, what client is used is impossible
 
 there is no user-agent like HTTP and even for HTTP the header is not

Not in general:

I guess, dovecot simply must learn it.

 And I just had an idea, but don't know if it is possible.
 
 Can I offer one namespace on one port (ie, SSL/993), and a different 
 namespace on the other port (STARTTLS/143)?

You dont' need 2 namespaces.

In 10-auth.conf set disable_plaintext_auth = yes


My 10-master.conf contains

| service imap-login {
|   inet_listener imap {

|   }
|   inet_listener imaps {
| port = 993

 I have compared Dovecot performance to Courier and it appears that as a POP3 
 server Dovecot is slower in 2 times but as an IMAP server it is faster in 1.5 
 times. The same node (16CPUs), testing time is 30 min, please see results and 
 dovecot configs attached.
 Benchmark software is MStone used by Sendmail Inc so is is quite reliable.
 
 I do not see anything else to tweak in Dovecot to increase POP3 performance. 
 Can we all have some tips to improve it please ?

The Middle Age has called, it wants POP3 back.

[Dovecot] Exim / Dovecot and AUTH LOGIN

[Frank Elsner]

Hi to both adressed mailing lists,

I followed the instructions in http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL

exim.conf:

|   plain:
| driver = dovecot
| public_name = PLAIN
| server_socket = /var/run/dovecot/auth-client
| server_set_id = $auth1
|   
|   login:
| driver = dovecot
| public_name = LOGIN
| server_socket = /var/run/dovecot/auth-client
| server_set_id = $auth1


10-master.conf for dovecot:

|   service auth {
| # auth_socket_path points to this userdb socket by default. It's typically
| # used by dovecot-lda, doveadm, possibly imap process, etc. Its default
| # permissions make it readable only by root, but you may need to relax 
these
| # permissions. Users that have access to this socket are able to get a 
list
| # of all usernames and get results of everyone's userdb lookups.
| # unix_listener auth-userdb {
|   #mode = 0600
|   #user =
|   #group =
| # }
|   
| # Exim SMTP AUTH
| unix_listener auth-client {
|   mode = 0660
|   user = exim
|   group = exim
| }


PLAIN Authentication works perfect, LOGIN gives

[130.149.X.YY]: 435 Unable to authenticate at present: authentication socket

Where is the problem?

 This is just a guess since I'm not too good at dovecot, but could it be 
 that you need to set at least auth_mechanisms = plain login your in 
 dovecot config?

Yeah, that was it! You made my day!

Hello,

What has dovecot to deal with my USB-Backup-Disk?

 No, but Dovecot doesn't really know what the mail filesystems are. You can 
 add:
 
 doveadm mount add '/media/*' ignore
 
 Perhaps this should be a default.

 Yes you are right.  Port 993 is for IMAPS (SSH).  TLS is normally on the same
 port as plain.
 
 The difference between SSH and TLS is that with SSH the encryption is set up
 before any application communication takes place.  i.e all application packets
 are contained in the encrypted payload.  With TLS the application starts
 communication and then the application sets up encryption of its payload.

 Hmm. I suppose it drops the privileges a bit too early now.. Well, you can 
 switch back to v2.0.12 behavior by removing the user=dovecot:
 
  service imap-postlogin {
   user = dovecot

Thanks, works.

 I'll fix it properly for v2.0.14 then. Another alternative would be to change 
 config socket's permissions to allow dovecot user to read/write it.

How to do that? 

PS: I'd like to have the lastlogin file to be owned by user dovecot.
Currently it is owned bx the user.

From the Log I guess you're using POP, right?

 When I telnet localhost pop3 and login into the account, the list

I guess the previous POP session downloaded them.

You may want to switch to IMAP.

 I'm a newbie at Dovecot. For a company groupware I need a kind of a

 Hi,
 
 I have some problem in Dovecot authorization in Exim for 
 outgoing SMTP.
 
 Version of Exim is 4.69 and the Exim was compiled 
 with AUTH_DOVECOT=yes and AUTH_PLAINTEXT=yes.
 Version of Dovecot 
 is 1.2.12.
 
 I use SSL for IMAP.  Is Exim neccesary to use SSL(TLS)
  for authorization of outgoing SMTP?

I guess NO because communication is via socket.

My exim-4.72 configuration (which doesn't use LOGIN) contains:

| plain:
|   driver = dovecot
|   public_name = PLAIN
|   server_socket = /var/run/dovecot/auth-client
|   server_set_id = $auth1


And the dovecot-1.2.12 configuration contains:

| auth default {
|   mechanisms = plain login
| 
|   passdb pam {
|  args = dovecot
|   }
| 
|   socket listen {
| client {
|   # The client socket is generally safe to export to everyone. Typical use

 Do I need some setings for auth_advertise_hosts or ACL in Exim configuration

Of course you should define to which hosts you advertise SMTP AUTH.
And within your ACLs you should allow AUTH only for SSL/TLS connections.

For example:

| hostlist   relay_hosts= 127.0.0.0/8 : 192.168.28.0/24
| auth_advertise_hosts  = !+relay_hosts
| ..
| acl_smtp_auth = check_auth
| acl_smtp_connect  = check_connect
| ..
| check_auth:
|   accept  hosts = +relay_hosts
|   accept  encrypted = *
|   denymessage = SSL/TLS encryption required for SMTP AUTH
| 
| check_connect:
|   warnhosts = +relay_hosts
|   control = allow_auth_unadvertised

 Dovecot would still be involved ... getting detected spam into a

 feedback folder for recycling false negatives into detection training.

Ok, you obviously have a different environment and requirements.

[Dovecot] Handling of file maildirsize

Hello,

My exim is doing the deliveries, dovecot handles POP/IMAP.

Exim Log shows:

2009-07-24 14:03:40 1MUJUy-0001Jr-B0 == u...@domain.tu-berlin.de R=maildir_user 
T=maildir_delivery defer (2): No such file or directory: while opening or

F=u...@domain.tu-berlin.de R=maildir_user T=maildir_delivery S=2061 QT=16m52s 
DT=0s


The user was active using IMAP at 14:03:4*. 

Therefor there must be a short period of time where no maildirsize exists.

Can this really happen? If yes, could this behaviour be changed?

 We are running a rather outdated mail server that until recently has been
 running beautifully.  Under the pretense of it is ain't broke, don't fix
 it it hasn't been updated so is running Fedora Core 4 and dovecot v0.99.14.
 
 What is happening is that as users log in (via thunderbird), they are shown
 the contents of their mailboxes.  However, when they try and access a given
 email, they get no response even if they wait upwards of 10 minutes.  I
 believe that the problem has arisen from their huge inboxes, several users
 have inboxes in excess of 4GB.
 
 Do any of you know how I could split these large mbox files down in to
 manageable chunks of 1GB?

I don't know. I know that maildir is far better for this situation.
You should 
- Upgrade dovecot
- Convert to maildir format

For the conversion to maildir refer to the discussion on this list.

 I suppose you mean you modified mail_executable to point to your own

Thanks, now it works as desired.

But ...  In http://wiki.dovecot.org/PostLoginScripting
the example for Last-login tracking says

Finally execute the imap/pop3 binary. If you use both, you'll need two 
scripts.

Is this a must?

My dovecot.conf currently contains

mail_executable = /usr/dovecot/libexec/dovecot/post-login imap
and
mail_executable = /usr/dovecot/libexec/dovecot/post-login pop3

And post-login reads

|   ...
| export QUOTA_RULE

This works.

 I only installed dovecot-common package.
 Also, i setted protocols to none.
 
 Does anyone know why i get that error message?

 Oh. According to the comments in my dovecot.conf setting protocols to
 none means that only dovecot-auth is enabled...
 What should i write under Protocols to just enable that?

My dovecot.conf contains
protocols = imap imaps

BTW, Please keep the thread on the mailing list, Cced here.

Re: [Dovecot] How to pull /var/mail mbox leftovers to Maildirs?

 I just got my preferred postfix+dovecot(-1.1.1) configuration working on

 I wasn't seeing inbound mail (in the email client) until I set:
 
 sudo postconf -e 'home_mailbox = Maildir/'
 
 Which I hadn't needed in the previous server's main.cf
 
 I have a few hours worth of inbound mostly-spam in /var/mail/(username)

 What command line tools could I use to pull those message from the mboxes
 to the Maildirs?

The attached script might help. 
I used it during migration from UW-IMAP to dovecot.
It worked, although I'm not the author :-)

 Is there a reason the rip/lip would say 127.0.0.1 for some small number of

Do you have a Web-Interface like SquirrelMail or Horde on the same host?

 These I/O leaks happen only when Dovecot is shutting down (it probably
 logged also killed by signal?). So although they shouldn't happen,
 here they most likely just mean that deinitialization wasn't done
 properly. I don't think it's worth the trouble to try to figure out why
 they happened.

Thanks. You're right, especially as it didn't happen again.

 I've the following problem with dovecot 1.0.7:


/var/log/messages shows

and /var/log/maillog shows (Please note: nearly the same time):

My squirrelmail talks imap to the server (localhost in my case) an does no

 One way (the most straightforward) is to use any of the available

[Dovecot] auth_cache_...

[Frank Elsner]

Hello,

the dovecot-example.conf states:

# Authentication cache size in kilobytes. 0 means it's disabled.
# Note that bsdauth, PAM and vpopmail require cache_key to be set for caching
# to be used.
#auth_cache_size = 0
# Time to live in seconds for cached data. After this many seconds the cached
# record is no longer used, *except* if the main database lookup returns
# internal failure. We also try to handle password changes automatically: If
# user's previous authentication was successful, but this one wasn't, the
# cache isn't used. For now this works only with plaintext authentication.
#auth_cache_ttl = 3600

auth_cache_size = 0, does it mean cache can grow ad infinitum 
 or does it mean no cache at all ?


Kind regards   __

   Just spotted the above error message (deleted previous posts already),
   and it strikes me as seriously odd.
   
   Dots in mbox file names are usually embedded (as in dovecot.org),
   where it makes sense, as opposed to beginning with a dot. Even worse,
   this particular name is kind of weird for a mail folder...
   
   However, this name is well known to me:
   
 [EMAIL PROTECTED] ~]$ ls -ld .gnome2_private
 drwx--  2 guenther users 4096 Jul 21  2005 .gnome2_private/
  
  Me Too :-)
 
 Hmm, so one of your users really got a mail folder named gnome2_private?
 Odd...

No, of course. It's one of the dot files, which nearly each application creates.

 Anyway, another idea hit me -- is this really an invalid name, as Timo
 said? I don't know the convert plugin and what it logs, and I don't know
 the exact details of Maildir either. However, creating a mail folder
 named gnome2_private in your MUA will result in a dir by that name
 with a leading dot. Just like the name in the error message, no?

Valid name or not, that's not the primary question.

What abot the idea to ignore directories and check the contents of files
for beeing am mail folder? If yes, then comes the question about the name.
 
   I'd check where the Maildir data actually is being created and what
   files are being attempted to convert. Almost looks like the Maildir dirs
   are being created in the users $HOME...
  
  No, dovecot.conf contains
 
 I did not want you to paste the settings again, but to check if the
 Maildir files are being created where you expect them. Grepping or
 changing conf files doesn't mean anything, if the running process
 doesn't use this particular version. ;)

The Maildir directory was created, but no folder converted.
BTW: Thanks for explaining trivia. :-)

I guess it's not a rare case for installations with UW-IMAP and
would make the switch to dovecot much more attractive :-)

 Won't do anything to v1.0. Maybe for v1.0.1. Anyway already implemented
 to CVS HEAD (which will become v1.1):

Thanks. I'll give it a try.

 You mean it doesn't work because you have these dot-directories? It
 would work if you didn't have them..

Tell this to the .gnome* and similiar people :-)

 This is most likely wrong. You're telling Dovecot that the user's
 non-INBOX mailboxes are in /var/mail. If you have only inboxes, set
 rather something like mbox:/some/empty/dir:INBOX=/var/mail/%
 u:INDEX=MEMORY
 
 Hmm. Since this seems to be so common problem, maybe I should make
 mbox::INBOX=/var/mail/%u work too..
 
  Any thoughts ? Is there a particular settings to use ? Anything wrong
  with my setup ?
 
 The real problem is that you didn't tell Dovecot to load the convert
 plugin:
 
 mail_plugins = convert

I have a similiar problem with dovecot 1.0.rc31.
Please note that /usr/dovecot is a link to /usr/local/dovecot on my system.
