Those knobs depend a on your config. If there is truly some resource limit causing this, it could be the vsz_limit of the (parent) process invoking your program. Which service is doing that depends on your config, either LMTP, the script service (when you're using socket programs), or dovecot-lda (so, basically your MTA - not controlled by Dovecot obviously).

Indeed it was vsz_limit. I set it to zero (under service lmtp) and now the script works.
However I’m noticing a couple things:
I previously had the vsz_limit unset, and subsequently set to 256M; neither worked.
I wrote a test script that just ran in a loop appending to a string and printing to stderr how long the string was; it was killed after it reported accumulating about 2MB.
Weird? or normal?
