Debian - postfix, dovecot... need some help here.
Hi there. I just migrate to my new server but I have some problems with my mail system.
I use debian squeeze with actual packages of postfix, dovecot, mysql.
I use for domains and mailboxes mysql, coz I can configure it easily by postfixadmin.
Now the problem specification: I can use my mailboxes to send the mails with no problem. But when I recieve mail, my client (thuderbird) crashes. I look at mail mailfolder and i find out that it recieves the mail with no problem to the folder *mailfolder*/new. But when I connect there with my client it does smth wrong coz it copy the mail to the folder *mailfolder*/cur with bad name (without the end flag)

example: 1277032543.Vfd00I3c1978M530835.mydomain:2,
it should be like: 1277032543.Vfd00I3c1978M530835.mydomain:2,S

when I put the flag there manualy everything is ok and I see the mail in the client

I know that I have the same problem one year ago on old server but I cant remember how i figure it out :(

Actually I use the same configuration files and mailfolders (with same owners) like on the old server, so there is possibility that I forgot configure something else (except postfix and dovecot).

Anyway thx for help, I am totally screwd. (And sorry for my english).

Now some configuration files:


# See /usr/share/postfix/ for a commented, more complete version

# line of that file to be used as the name.  The Debian default

just test fresh configs from packages dovecot and postfix with this setup and the result is the same --> everything is ok until i try recieve mail by client, then again the FLAG in the end of mails names is missing

I just tried the m$ outlook 6 and it seems that it can handle "the messages without flag on the end of filename".

Thunderbird 2 & 3 still crashes, any ideas? :/
