I see the following lines in my logs: Apr 26 20:53:30 xenvps postfix/smtpd[19000]: connect from mail-sn1nam01on0125.outbound.protection.outlook.com[104.47.32.125] Apr 26 20:53:30 xenvps postfix/smtpd[19000]: setting up TLS connection from mail-sn1nam01on0125.outbound.protection.outlook.com[104.47.32.125] Apr 26 20:53:30 xenvps postfix/smtpd[19000]: SSL_accept error from mail-sn1nam01on0125.outbound.protection.outlook.com[104.47.32.125]: -1 Apr 26 20:53:30 xenvps postfix/smtpd[19000]: lost connection after STARTTLS from mail-sn1nam01on0125.outbound.protection.outlook.com[104.47.32.125] Apr 26 20:53:30 xenvps postfix/smtpd[19000]: disconnect from mail-sn1nam01on0125.outbound.protection.outlook.com[104.47.32.125]
It looks like some kind of problem negotiating TLS, but other sites can send me email using TLS with no problems. I am using a self-signed certificate. Any ideas what is wrong and how to fix it?
