Hi Timo,

You have to download and compile it:
http://dovecot.org/patches/1.1/listescape-plugin.c

Note that it requires that you have Dovecot sources downloaded and
compiled. They also should be for the same version you're actually
using.

Timo,

i use dovecot with postfix mysql  virtual user / domains

mail_location = maildir:/home/mail/%d/%n



Timo Sirainen schrieb:

No idea.

But actually there's also another possibility that doesn't involve using
plugins. You could just not use Maildir++ layout by setting e.g.:

mail_location = maildir:~/Maildir:LAYOUT=fs

SSL just binds to special port(like 993 in IMAP by default).


No, SSL is a protocol, just like TLS. It doesn't bind to any ports.
http://wiki.dovecot.org/SSL



To illustrate, both SSL and TLS as implemented in Dovecot utilize "SSL 
certificates."


A typical "TLS" session will work as follows:

1  The client connects to the IMAP service on port 143, unencrypted.
2  The server announces that it speaks TLS.
3  The client says "Ok, let's talk encrypted."
4  Magic occurs, and the session becomes encrypted. This step is where
   your "SSL" certificate is used.
5  The rest of the session is encrypted.

/Usually/, when people refer to SSL as opposed to TLS, they mean IMAPS 
or POPS. These differ in that there's no "Hey, I speak TLS" step. It 
is assumed that the conversation will begin according to some secure 
protocol, kind of like when you connect to a web server on port 443.


1  The client connects to IMAPS on port 993, and performs the secure
   handshake. Your "SSL" certificate is used in here somewhere.
2  Once the handshake has completed, the rest of the session is secure.

When implementing IMAPS/POPS you will usually use a different port, 
because if you tried to talk plaintext to the server, it would appear 
to be speaking gibberish (whatever secure protocol is being used).


With TLS enabled on a normal IMAP port, the switch from plaintext to 
encrypted is optional. Although, it's usually a good idea to force 
TLS, too.


Much of the confusion comes from the fact that you can use either 
protocol, TLSv1 or SSLv3 after the "Hey I speak TLS" step. Likewise, 
you can use TLSv1 with IMAPS or POPS, though it's use will be implied 
and there will be no "Hey, I speak TLS" step. There's really no 
agreement amongst mail clients as to the meaning of "Use SSL" and "Use 
TLS."


You may find it easiest to concentrate on the one distinction: does 
the session begin encrypted, or does it switch from plaintext to 
encrypted at some point? Once you've answered that, either of the 
SSLv3 or TLSv1 protocols can be used, and they will both use your 
"SSL" certificate.


Ultimately, you may wind up using both, depending on your user base. 
Many versions of Outlook are screwy with regard to one or both of 
these methods.


From Outllok  Version 2007 u can choose between SSL / TLS in Settings 
of the mailaccount. In Outlook 2003 we experienced the only choosable 
SSL can also work

with TLS.
BUT, we found out, Outlook 2000 & 2002 cant work with any of our 
"forced" TLS Mailservers.
Also Microsofts ENTOURAGE or whatever named Client cant work with TLS 
and some "Mail" Clients from OS X, but latest do.

hope that helps

I am just trying to figure out how it works. Your help from Friday 
motivated me. :-)

Why don't you do the ebuilds yourself? It's not that hard.


  

Thanks,

I know this may come as a shock to you, but not everyone is a
programmer, or understands this stuff well enough to write their own
software.

Why do you use the kernels put out by kernel.org? Why don't you just
code your own?

Elitist crap...
