This is more of an annoyance than anything else. When my Postfix (v

Mail is still sent despite warning. Suspect that problem is either:
1. Using a self-signed certificate and need to purchase one to use
with mail server.
What does that have to do with your mail server logging a remote issue ?
If this is the case, would appreciate recommendations/weblinks on good
places to purchase.
2. Configuration error. Partial main.cf is below:
/smtpd_use_tls = yes/
/smtp_use_tls = yes/
That is the problem. Are you only sending to one relayhost, and does
this require TLS ?
FYI, the internet at large does not use TLS for normal mail transport.
