[Dovecot] which e-mail client can work with recent dovecot?

[Sergey Ivanov]

Hi,
I'm trying to use dovecot-1.0.rc7.

Before I've used dovecot-1.0 from nightly cvs build of August 08, 2006.
It worked perfectly, on Linux 64-bit, you can see spec and patches at
http://www.sisyphus.ru/srpm/dovecot/

When I tried to upgrade to rc7 and to recent nightly cvs builds with the
same configuration and patches (provided necessary adaptations), it
builds O.K, but can not move messages from folder to folder.

I've tried the following mail clients: thunderbird-1.5.0.7,
evolution-2.0.2, sylpheed-claws-2.0 and KMail-1.7.1 (all from
Centos-4.4). KMail refuses to copy (or to move) multiple selected
messages, saying:" Error while copying messages.Connection to Server
Closed Unexpectedly ...". Evolution is not able to open folders at 3-rd
level (like dovecot/2006/09), or it is so slow that I was not able to
test moving/copying messages in it. Sylpheed-claws died whan I tried
this message copying. Thunderbird tries to move infinetly in a loop,
filling the dovecot's log with lines:

(approximitely 2 cicles per second).

And when I reinstalled back the previously worked version of dovecot,
the problem remains.
