Description: As of version 3.5.5 smtpd is crashing


Additional info:
3.5.4 works fine.
After update there are problems and smtpd crashes.

On my system, the are 2 mail servers - one on the border just behind a firewall, and the second is the internal mail server.
After the update from 3.5.4 to 3.5.5 a test email was sent from gmail, the border mail server contacts the internal mail server where:

on internal server:

connect from _gateway[xx]
openarc[1130]: assuming verify mode for host _gateway
postfix/master[2435]: warning: process /usr/lib/postfix/bin/smtpd pid 2497 killed by signal 11
kernel: smtpd[2497]: segfault at 55f021b02000 ip 00007f2793814c68 sp00007fff02c04010 error 4 in libcrypto.so.1.1[7f2793802000+1a5000]

On border router:
SSL_connect error to internal.x.y [xx]:25: lost connection

Both systems are fully up to date on testing repo.

rolling back to 3.5.4 all works normally as before.
Both servers were rebooted after the update before testing.
