Recommendations on intrusion prevention/detection?
Dear all,
what are the key strategies for intrusion prevention and detection with
dovecot, apart from installing fail2ban?
It is a pity that the IMAP protocol does not support 2 factor
authentication, which seems to stop 90% of intrusion attempts in their
tracks. Without it, if someone has obtained your password and reads your
mail without modifying it, you will hardly ever notice.
Is there a

Hi!
I understand that it is not trivial to move away from vpopmail and does require changing a working system. But then again, one should be able to configure MySQL passdb/userdb with vpopmail schema.
I am not familiar with vpopmail but if someone comes with instructions we can polish them a bit (if necessary) and publish them as howto on doc.dovecot.org.

So I am on of the many users with qmail, and using vpopmail auth, I guess chatting with some other guys in the other mailing list we will convert to mysql driver but this is a lot of work for many people.
I do understand dropping things out but a valid solutions needs to be proposed.

[FOR THE RECORD] CLIENTID Extension for IMAP/SMTP AUTH in dovecot
More and more email clients are now starting to support the CLIENTID
extension for IMAP, including 'libetpan', SaneBox, BlueMail, and now as
of Thunderbird 68.5.0, available there as well.
This allows for a form of native two factor support, permission token,
and/or access control to prevent the unauthorized use of email address
and password. (For more information, please see the RFC

With these planned changes, you mention they will be removed from
'core', so is the intention to allow more of these legacy plugins to
more to their own repo's for those that might still want to use them?
Eg, more in the the path of plug-in architecture? Just curious for
clarity.
Oh, and have to add.. still waiting on the variable capability patch, to

Problem with atwin2k.. and debugger output..
DOH! THe probelm was what I was seeing WASN'T the output of the debugger..
The debugger SEEMED to run, but what it was is that there was no font
directories to search (BTW, how do we specify a xfs server?)
Anyways, now that I added a font directory, the real debugger actually comes
up, and shows the following...

NFS Locking and Submission Service Authentication
For the record, ever since the last patches for NFS got committed, we
don't see locking issues over NFS in general across all our platforms,
but it also depends on how you configure your NFS server.
You might find that this is not a dovecot issue, but an NFS issue.
You might want to post more about your NFS setup(s) and then someone on
the list might better assist you.
