'lost connection after CONNECT' means the far end connected and then
disconnected. Maybe the client has a buggy TLS. You can
selectively turn off TLS for that client by setting:
# main.cf
smtpd_discard_ehlo_keyword_address_maps =
cidr:/etc/postfix/smtpd_keyword_maps
# smtpd_keyword_maps
99.98.44.85 STARTTLS
