[Dovecot] Sieve problem. Timo, is this mbox file size limitation hard coded? If so, why?

[Stan Hoeppner]

I would not have expected this upon implementing sieve.  And I really need
to get around this limitation.  LDA has no problem writing to these large
mbox files.  Why does sieve have a problem with them?  This is very odd.

Is there any reason we have a fixed ceiling on the size of an mbox sieve
will write to?  Man this is disappointing.  What is the ceiling?  It appears
to be somewhere between 30MB and 56MB as writes to 1-Postfix-Users are
successful but writes to 1-Spam-l fail.

Is there a fix/patch for this?

Thanks.
