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 = 5120000000
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 ?

Either this is an old version or you snipped the version from the top of
the dovecot -n output...
What version of dovecot?
Also, OS/version info may help too...

So this is 5 GB. I don't know how exactly the limits work with 32 bit
systems, but if you get the error with >1 GB files then my guess is that
this 5 GB gets wrapped to 1 GB (5 mod 4 = 1).

Kernel gives this error when it reaches the maximum file size limit.
If you don't want a limit, just set mailbox_size_limit = 0.
Hi,
Setting mailbox_size_limit to 0 made deliveries possible. a limit of 2000000000
(<2GB) also did not show the errors. 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.
I guess this is result of using integer values for size limit. values greater
than 2GB would wrap and cause warnings in postfix. Probably, my previous limit
of 5GB would confuse things and no error was reported. (I don't know how, 5GB
cannot be stored in an unsigned int, double overrun makes it within limit ? :) )
Maybe moving to "long long int" for mailbox file size is a possible solution.
