Re: [Dovecot] mbox file too large error with deliver

Thank you ! :) My issue is fixed but deliver might have a bug, so I will explain things, sorry for not being clear previously. Old mail server was 32 bit(an old version of debian) and used procmail for deliveries, that setup worked with the given limit of 5GB and mailbox sizes above 1GB. After migrating to an 64 bit server (debian etch) and dovecot's deliver, the stated delivery errors appeared for mailboxes above 1 GB. As I stated at the beginning of my reply, setting mailbox_size_limit below 2GB made deliveries possible. I tried with edge values, mailbox_size_limit=2147483648 (exactly 2GB) would give the following error in postfix logs: fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit A limit of 2147483648 - 1 worked fine. There are two distinct bugs probably, one in postfix and one in dovecot. Postfix clearly is using signed 32bit integer here, which could be considered a bug. But why do you think there's a bug in Dovecot? Note that Dovecot never even sees this value. It's the kernel that enforces it, Dovecot simply reacts to a write() failure. The logs stating the File too large errors belong to dovecot's deliver process. While I was searching for a solution, I read that deliver honors mailbox_size_limit setting of postfix, I'm not sure if that is correct or not. Note that the destination mailboxes are smaller than 2GB here, but still gets File too large error. The machine is 64-bit, so no fs related kernel limits on file size. I have not dived into postfix and/or dovecot internals, but my guess is , dovecot gets the mailbox size limit and behaves accordingly. If that is the case, the problem can be fixed in dovecot's deliver code. If postfix sets file size limit with ulimit before execing deliver, OR uses a similar process which is out of deliver's control, then there is nothing concerning dovecot. If someone can clarify the issue I would be happy. -- Gokdeniz Karadag
[Dovecot] mbox file too large error with deliver
Hi, I am using dovecot on debian, with version 1.0.rc15-2etch4. Along with postfix. The deliver binary cannot deliver to large mailboxes. I cannot state an exact size limit but mbox mailboxes above 1GB seem to be affected. I have these in in postfix/main.cf mailbox_command = /usr/lib/dovecot/deliver mailbox_size_limit = 512000 The user.log file shows these (I believe if no logging is specified, deliver binary tries to log with logger and they go to user ?) user.log.3.gz:Nov 8 21:23:01 guvercin deliver(dummy): write() failed with mbox file /var/mail/dummy: File too large user.log.3.gz:Nov 8 21:23:01 guvercin deliver(dummy): msgid=[EMAIL PROTECTED]: save failed to INBOX user.log.3.gz:Nov 8 21:23:01 guvercin deliver(dummy): sieve runtime error: Keep: Generic Error The /var/mail/dummy file exists and is 1.9GB, so my filesystem certainly supports files 1G What may be the problem ? dovecot -n output follows : log_timestamp: %Y-%m-%d %H:%M:%S syslog_facility: local1 protocols: imaps pop3s ssl_cert_file(default): /etc/ssl/certs/imap-cert.pem ssl_cert_file(imap): /etc/ssl/certs/imap-cert.pem ssl_cert_file(pop3): /etc/ssl/certs/pop-cert.pem ssl_key_file(default): /etc/ssl/private/imap-key.pem ssl_key_file(imap): /etc/ssl/private/imap-key.pem ssl_key_file(pop3): /etc/ssl/private/pop-key.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u:INDEX=/var/spool/dovecot/indexes/%u mbox_read_locks: fcntl dotlock mbox_write_locks: fcntl dotlock mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds(default): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xv%08Xu pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master:
