TLS 1.3 log lines not parsed

[olvsa]

Current regex does not parse TLSv1.3 connections.

Log line example:
Nov 08 10:07:48 mx-3 postfix/smtpd[323791]: Trusted TLS connection established from mx-1..[192.168.1.1]:38929: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (4096 bits) client-digest SHA256

Regex for smtpd does not expect this format because log line has text after "with cipher TLS_AES_256_GCM_SHA384 (256/256 bits)".

Regex smtpdTLSLine (0.3, 0.2 versions):
smtpdTLSLine = regexp.MustCompile(^(\S+) TLS connection established from \S+: (\S+) with cipher (\S+) \((\d+)/(\d+) bits\)$)

Same things for smtp.
BTW, thanks for exporter!
