Hello,

I'm running OpenSMTPD 7.5.0p0 on Linux

And recently I'm started getting such errors for e-mails coming from 
outbound.protection.outlook.com servers.

Jun 17 10:20:39 smtp01 smtpd[7838]: 33c0e6f7addb24d1 smtp connected 
address=40.107.127.99 host=mail-be0deu01on2099.outbound.protection.outlook.com

reason="io-error: write failed: Connection reset by peer"

Is my understanding correct that "Connection reset by peer" means that remote 
host (outlook.com) closed/reset the connection?

Is there a way to debug whats is going on in such situation?

What could be the reason for such resets?

Thank you,
