Hi Let's list some files in user homedir:

dog:/home/domain/users/username# ls autoresponse dovecot.index.log dovecot-uidvalidity.4be1e480 saved trash config dovecot-uidlist new sent cur dovecot-uidvalidity tmp dog:/home/domain/users/username# ls cur 1273093948.30793.dog:2 dog:/home/domain/users/username# ls new 1273097763.13545.dog 1273118766.1674.dog

As you can see one mail is in cur and two new mails are in new folder. Let's fetch them via pop3:

dog:/home/domain/users/username# nc -v localhost 110 localhost.localdomain [127.0.0.1] 110 (pop3) open +OK Dovecot ready. user username@domain.pl +OK pass secret +OK Logged in. stat +OK 1 7824 quit +OK Logging out. dog:/home/domain/users/username#

It said there is only one mail. Where are my new mails? Let's check log file:

May 6 07:42:46 dog dovecot: POP3(username@domain.pl): Effective uid=1002, gid=1002, home=/home/domain/./users/username May 6 07:42:46 dog dovecot: POP3(username@domain.pl): maildir: data=/home/domain/./users/username May 6 07:42:46 dog dovecot: POP3(username@domain.pl): maildir++: root=/home/domain/./users/username, index=, control=, inbox=/home/domain/./users/username May 6 07:42:46 dog dovecot: POP3(username@domain.pl): Namespace : Using permissions from /home/domain/./users/username: mode=0700 gid=-1 May 6 07:42:46 dog dovecot: pop3-login: Login: user=username@domain.pl, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured May 6 07:42:52 dog dovecot: POP3(username@domain.pl): Disconnected: Logged out top=0/0, retr=0/0, del=0/1, size=7824

No error logged looking at the good dir. Permissions OK. When I remove dovecot.index.log new messages appears:

dog:/home/domain/users/username# rm dovecot.index.log dog:/home/domain/users/username# nc -v localhost 110 localhost.localdomain [127.0.0.1] 110 (pop3) open +OK Dovecot ready. user username@domain.pl +OK pass secret +OK Logged in. stat +OK 3 76974 quit +OK Logging out. dog:/home/domain/users/username#

Any clue what can it be?
