postfix -1 read errors

Alef Veld
Hi all.
I’m a bit worried about the following read errors i see in my log lately. Mails still arrive and get sent fine, but what is going on with this? It doesn’t look good. Nothing has change on server side and i restarted all services (dovecot, postfix, saslauthd, sql ).

Maybe it’s a temporary iPhone thing (the device im using to read and send mails, not the first time that happened. Maybe changing the port will do the trick).

Thanks for looking.

The logging you show is from postfix, this is the dovecot list.

If you ask on postfix-users, they'll probably tell you something
similar to: There's no problem here, set smtpd_tls_loglevel to 0 or
1; same for smtp_tls_loglevel
