Apologies for pointing the finger at lda/sieve. After much digging and Googling I found that the problem actually lies with a Postfix default setting, specifically:
"mailbox_size_limit (default: 51200000)
The maximal size of any local(8) individual mailbox or maildir file, orzero (no limit). In fact, this limits the size of any file that is written to upon local delivery, including files written by external commands that are executed by the local(8) delivery agent.
This limit must not be smaller than the message size limit."I set it to zero and that fixed the problem. This is indeed one strange situation. The error was reported in the log by dovecot, but the setting that fixes the problem is actually in Postfix. It would be nice if there was a short heads up regarding this in the dovecot wiki postfix LDA and/or sieve sections. I'll mention this on postfix-user as well.

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.
