Problem description: POP3 client can't fetch second e-mail message from Maildir if first POP3 connect occurs before any message placed in Maildir.

Details:

1. POP3-client first time tries to receive mail:

May 14 16:17:36 host dovecot: pop3-login: Login: user=user@mydomain.ru, method=PLAIN, rip=192.168.0.100, lip=192.168.0.3 May 14 16:17:36 host dovecot: POP3(user@mydomain.ru): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0

dovecot creates Maildir for that user:

/var/mail/virtual/mydomain.ru/user/Maildir/ /cur /new /tmp dovecot.index dovecot.index.cache dovecot.index.log

2. Postfix MTA receives message for that user and places it at /var/mail/virtual/mydomain.ru/user/Maildir/new/1179145269.V43I3f5a4M116738.host.mydomain.local

3. POP3-client tries to receive mail:

May 14 16:23:09 host dovecot: pop3-login: Login: user=user@mydomain.ru, method=PLAIN, rip=192.168.0.100, lip=192.168.0.3 May 14 16:23:09 host dovecot: POP3(user@mydomain.ru): Disconnected: Logged out top=0/0, retr=1/786, del=1/1, size=770

dovecot creates file dovecot-uidlist with next_uid=1 (!!!): 1 1179145056 1 1 1179145269.V43I3f5a4M116738.host.mydomain.local:2,

Message fetched successfully.

4. POP3-client tries to receive mail:

May 14 16:23:29 host dovecot: pop3-login: Login: user=user@mydomain.ru, method=PLAIN, rip=192.168.0.100, lip=192.168.0.3 May 14 16:23:29 host dovecot: POP3(user@mydomain.ru): UID larger than next_uid in file /var/mail/virtual/mydomain.ru/user/Maildir/dovecot-uidlist (1 >= 1) May 14 16:23:29 host dovecot: POP3(user@mydomain.ru): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0

File dovecot-uidlist disappears.

5. Postfix MTA receives message for that user and places it at /var/mail/virtual/mydomain.ru/user/Maildir/new/1179145534.V43I3f5a4M116827.host.mydomain.local

6. POP3-client tries to receive mail:

May 14 16:47:20 host dovecot: pop3-login: Login: user=user@mydomain.ru, method=PLAIN, rip=192.168.0.100, lip=192.168.0.3 May 14 16:47:20 host dovecot: POP3(user@mydomain.ru): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0

Dovecot creates file dovecot-uidlist: 1 1179145056 2 1 1179145534.V43I3f5a4M116827.host.mydomain.local

Dovecot moves message from new to cur directory and adds flag ":2,":

/var/mail/virtual/mydomain.ru/user/Maildir/cur/1179145534.V43I3f5a4M116827.host.mydomain.local:2,

Message not fetched. And POP3 client can't fetch it at all.

All next messages fetches normally as they arrives.
