Newbie why is dovecot classified diff then sendmail or courier

[David Niklas]

Hello, this is probably a dumb question, but I can't for the life of me
figure out why sendmail and courier are classified universally as
network-mail-mta whereas dovecot is in places like network-mail-general
or some such place. I've used several Linux distros and have noted this
keenly (they also normally classify photorec, the HD recovery tool as
hardware-photography,so this may just be a mistake).
I'm concerned that I'm looking into the wrong software for an mail
transport/delivery agent.

Thanks, David

No, but I think it should be changed to do that always.. That would be a v2.3 
change though.

v2.2.19 release candidate 2 released

[Timo Sirainen]

http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc2.tar.gz
http://dovecot.org/releases/2.2/rc/dovecot-2.2.19.rc2.tar.gz.sig

There were still a bit too many bugs in RC1, so here's RC2. Hopefully this will 
be stable enough to become v2.2.19 final. Please test now rather than wait for 
v2.2.19 final, since v2.2.20 is unlikely to arrive anytime soon (unless there 
are some major problems).

Some fixes since RC1:

 - dict fixes, especially with pgsql
 - virtual plugin crashfixes
 - quota "count" backend fixes
 - lib-http fixes
 - some compiling fixes

No, it's only impossible if you are using passdb or otherwise
authenticating against real users of the system.  If you are using
virtual users (SQL, LDAP, etc.), you can include the domain name in the
auth lookups.

Re: object storage

[Tom Johnson]

I went to them to discuss 300-500,000 users, right after dovecot was  acquired 
by OpenXChange. The terms were onerous, to say the least.  It was straight 
per-user pricing with no flexibility for non-standard usage patterns.  Mostly 
they wanted to talk about OpenXChange, in which I have absolutely no interest. 

I walked away undecided: would I look at developing my own object storage 
back-end for dovecot and open-source it?  Or would I abandon dovecot entirely?  
I'm still undecided.

I do this by creating a 2nd startup script / systemd service
you can then use another dovecot config file and specify different
listen IPs (and Ports). This is also useful for different SSL certs per
domain / ip, etc.

the dovecot service does not care about the server dns name. the dns
name resolves to the IP address on the client (roundcube) and the client
connects to the server. if the same dovecot instance listens to all /
both IP address, client will end up on this dovecot instance and all
valid user-password combinations are authorized. that's the way it has
to be, otherwise virtual / mass virtual domain hosting would not be
possible as you cannot spawn 1000 instances on the same machine (ok, in

mirroring one domain.tld to domain.tld.au

[voytek]

I have Postfix/Dovecot/postfixadmin/MySQL with several virtual mailbox
domains

one of the domains is like aname.com.au, the user also now has aname.com,
and, would like to 'mirror' most of the addresses to be u...@aname.com,
THOUGH, some are to remain as us...@aname.com.au

so, both u...@aname.com as well as u...@aname.com.au should be one user

the users retrive emails as u...@aname.com.au

longer term... some would want to use aname.com.au. some, aname.com

what's the best/proper way to do so in Dovecot ?

I think I can do Postfix with postfixadmin to "Mirror addresses of one of
your domains to another."

but what do I do at the Dovecot end...?

thanks for any pointers, suggestions or advice

Re: distuguish between different domains

[Marco Fretz]

Hi Andreas,

I'm not 100% sure what you're trying to accomplish.

smtp_server in roundcube is the outgoing server (submission server, i.e.
postfix). Mailbox is IMAP (dovecot).
You can easily spawn 2 instances of dovecot, one serving aaa.de and one
serving bbb.de on different IPs.

What exactly is the problem with 2 domains on one dovecot? I mean user
@aaa.de usually does not have the password for @bbb.de and vise versa.

About the sending server in roundcube: I don't think there is a way to
have a different submission server for different sender domains in
roundcubde. But you could use the postfix configuration to map sender
domains to different outgoing connection IPs.

Does this help? If not, please tell us more about what you're trying to do.

regards
Marco

Re: Problem with SHA2/Geotrust and dovecot 2.0.9

[Marco Fretz]

Hi,

does the cert work if you open and output it as text with openssl command?
not sure if 2.0.9 does support sha2, I think it should - I guess it
actually depends on openssl libs not dovecot.

Re: Sieve and forward

[Marco Fretz]

Hi,

I think the problem is you cannot resign the forwarded message... and if
you keep the original sender domain it looses the signature? I'm not a
DKIM guru though :-) Maybe just forward it as attachment from the users
address...

You are completely wrong ;) If the mailbox exist server handles it,
there's no difference from/to which "domain" was the connection. Besides
you can configure Roundcube to select server IP/host based on logon domain.

Error saving to IMAP folder

Hi,

I have been using dovecot for multiple years, without a problem so far.
I'm running version 2.0.19-0ubuntu2.2.

A few weeks ago, the following problem started. When sending an e-mail
with Thunderbird, the message is saved to the "Sent" IMAP folder after
sending it out. Every few days, this

How do I do this?

What is irritating me is that when there are two domains served by
dovecot, in the client I can specify server.aaa.de although I have
an email-address u...@bbb.de and connect as such.

For my understanding it should not be possible to connect to server
server.aaa.de with an address line u...@bbb.de and dovecot serves
the mailbox of that user.

Postfix is not the problem. It's the login into the IMAP-server that
is irritating me. Or am I completely wrong?

It makes not difference when I define 
$rcmail_config['default_host'] = 'tls://mail.bbb.de';
in Roundcube. I guess the advantage of this setting
is to identify the server when the server are running
on different machines. But as long as the domains reside
on the same machine, it does not matter.

I can login as u...@aaa.de and the mailbox is served.
That's what is irritating me. But I can life with it.

Interesting. So che choice for object storage is driven by the number of

Since they sell it with a pricing /user, the data stored should not 
matter to them.
