I am sorry, but still I cannot reproduce the crash here. I need further debug information. Can you please update to 8.164 and trigger full debugging for the SMTP proxy by running the following command once on a root shell on the ASG:
kill -USR2 $(pgrep -o smtpd)
Once the SMTP proxy crashed again, please post the new smtpd_debug.old.log.
