[Dovecot] Trouble with Trash

[Dominic Pratt]

Hi guys and girls,

Version: 2.0.19 - running on Ubuntu 12.04 LTS Server
dovecot -n:

# 2.0.19: /etc/dovecot/dovecot.conf
# OS: Linux 3.3.1 x86_64 Ubuntu 12.04 LTS
mail_location = maildir:~/Maildir
managesieve_notify_capability = mailto
managesieve_sieve_capability = fileinto reject envelope

relational regex imap4flags copy include variables body enotify 
environment mailbox date ihave
passdb {
driver = pam
}
plugin {
sieve = ~/.dovecot.sieve
sieve_dir = ~/sieve
}
protocols = imap pop3 sieve
service auth {
unix_listener /var/spool/postfix/private/dovecot-auth {

}
}
ssl_cert = </etc/ssl/certs/dovecot.pem
ssl_cipher_list = 
ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM
ssl_key = </etc/ssl/private/dovecot.pem
userdb {
driver = passwd
}
protocol imap {
imap_client_workarounds = delay-newmail
mail_max_userip_connections = 10
}
protocol pop3 {
mail_max_userip_connections = 10
pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
}
protocol lda {
deliver_log_format = msgid=%m: %$
mail_plugins = sieve
postmaster_address = postmaster
quota_full_tempfail = yes
rejection_reason = Your message to <%t> was automatically rejected:%n%r
}

My problem is, that actually old mails in the Thrash-Folder are deleted. 
This is crap, because I want to look at some mails again. I'm not sure 
if my Thunderbird does it or Dovecot. I don't think, TB does it, there's 
actually no option, I think.

Any ideas?

P.S.: Sorry for the bad english.
