Description of problem: Hello, I am having problems with Dovecot not delivering 'big' emails. Small email with 1-2 kb text delivered fine. If the message about 200kb long or more it freezes. I am also getting "copy: i_stream_read() failed: Permission denied" erros in Dovecot log files. I have tried switching off selinux and settings 777 permissions to my mail_location - it both dont help. Here is my cfg info: # 1.2.0: /etc/dovecot.conf # OS: Linux 2.6.29.5-191.fc11.x86_64 x86_64 Fedora release 11 (Leonidas) ext4 protocols: imap pop3 listen: * ssl: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: PREVED MEDVED first_valid_uid: 8 last_valid_uid: 8 first_valid_gid: 12 last_valid_gid: 12 mail_location: maildir:/home/email/%d/%n mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 432 user: mail group: mail Version-Release number of selected component (if applicable): I'm running FC11 with exim and dovecot installed.

http://hg.dovecot.org/dovecot-1.2/rev/6d7f6ea02e17 Problem is solved. homedir should not be relatibe path, but absolute; it seems was a pure luck that relative paths works for me before. It seems relateve homedirs will not be supported in future versions of Dovecot: http://hg.dovecot.org/dovecot-1.2/rev/dd49cf3fd2c9
