so to summarize: postfix (what version?) dovecot-antispam plugin (version? Installed from where?)
and when your script invokes deliver you get a core dump. Have you a stack-trace from that coredump?

What OS/MTA are you using? Can you give me (privately if you want) a re-hash of the LDA issues?
I'm using FreeBSD 10.3 / Exim for my set up and LMTP for ALL deliveries, and it works great.
Thanks again for your willingness to help with this, Larry.
I'm using Postfix.
Regarding the OS, I'm using Ubuntu 16.04 here, which ships dovecot 2.2.22 at present.

Sure, a quick recap of the crashing issue I'm having with dovecot-lda:
I struggled to get this working the first time (in dovecot 2.0.19), but prevailed with lots of help from this list. I described the roadblocks I encountered along the way in this thread:
http://www.dovecot.org/list/dovecot/2013-June/091018.html
All was well until I upgraded from Ubuntu 12.04 LTS to 14.04 LTS and thereby from Dovecot 2.0.19 to 2.2.9. To be clear (and it may be very relevant), this was a "manual" server migration and not an OS-level/package-managed upgrade. Point being, the potential to botch some aspect of the extremely fragile configuration was absolutely present!
I wrote about the problems I encountered after the upgrade here:
http://www.dovecot.org/list/dovecot/2014-July/097234.html
The thread died-out, but I rekindled it here:
http://www.dovecot.org/list/dovecot/2014-August/097385.html
I ran out of steam after a soft dead-end.
I wrote more about it a couple months later, mostly in the context of difficulty with dovecot-lda logging in an effort to debug the issue, but the thread received no replies:
http://www.dovecot.org/list/dovecot/2014-October/098127.html
Nearly two years later, I tried again:
http://www.dovecot.org/list/dovecot/2016-August/105221.html
The thread received some traction, and I changed the subject line to be more accurate partway through, which begins here:
http://www.dovecot.org/list/dovecot/2016-August/105236.html
I ended-up running with Karol's final suggestion, which was to forego the LDA in favor of a simple filesystem move/copy operation.
But now the problem I'm having (to bring it full circle!) is that I can't mark the Antispam plugin's incoming emails as seen/read automatically because they aren't delivered by an LDA. And I want to get this working with an LDA again for this reason, among others, such as quotas not being enforced when a "trained" message is "copied" on the filesystem instead of "delivered" via an LDA.
The more I think about this, the more I think I should go back and study the very first thread from June, 2013... maybe the solution is more or less the same!
