Mira, eso pasa cuando se corta la conexion TLS antes de que postfix
responda, verfica a ver con cliente te da ese error.
Muchas veces pueden ser spam bots entonces no tenes porque preocuparte.

# SOFT BOUNCE
#
# The soft_bounce parameter provides a limited safety net for
# testing. When soft_bounce is enabled, mail will remain queued that
# would otherwise bounce. This parameter disables locally-generated
# bounces, and prevents the SMTP server from rejecting mail permanently
# (by changing 5xx replies into 4xx replies). However, soft_bounce
# is no cure for address rewriting mistakes or mail routing mistakes.

Post by Wilmer ArambulaBuenos Dias tuvieron que cambiar mi vps de nodo por problemas con las
ips, todo funciona bien recibo y envio correo por
postfix+postfixadmin+dovecot+clamav+spammassing el problema es que ahora me
genera el siguiente error en el maillog, creo que ya cambie la ip en todos
los sitios que deberia hacerlo, busque en google y no encuentro alguna
network_biopair_interop: error writing 31 bytes to the network: Broken pipe
Saludos,
