[Dovecot] Mails don't get deleted after POP3
Hi, there!
Well, I am new to dovecot, so please be patient with me:
I have a virtual server and want to setup simple mail delivery.
postfix, saslauthd and dovecot basically work fine.
The only open issue is, that (I guess) dovecot doesn't remove the
mail when it's retrieved via pop3 from the server.
It keeps sending me the same emails again and again.
(The mail client (Thunderbird) is configured to remove the messages
from the server - it was working already.)
I guess that dovecot cannot write to some files / has problems
with write permissions. But it doesn't tell me anything...
Can you tell me, what configuration might be wrong or how can I
enable more debugging to see what dovecot is doing after
the mails got sent out via pop3?
Here is the configuration:
# dovecot -n

[Dovecot] Mails don't get deleted after POP3 [SOLVED]
Hi, there! > I guess that dovecot cannot write to some files / has problems > with write permissions. But it doesn't tell me anything... The reason was indeed that dovecot couldn't write to /var/mail I had to chown it to the mail group as it says in: mail_privileged_group: mail Thank you, Regards, Rob Am 08.11.2012 22:21, schrieb cullinan at rocketmail.com:> Hi, there! > > Well, I am new to dovecot, so please be patient with me: > > I have a virtual server and want to setup simple mail delivery. > postfix, saslauthd and dovecot basically work fine. > > The only open issue is, that (I guess) dovecot doesn't remove the > mail when it's retrieved via pop3 from the server. > It keeps sending me the same emails again and again. > (The mail client (Thunderbird) is configured to remove the messages > from the server - it was working already.) > > I guess that dovecot cannot write to some files / has problems > with write permissions.
