[breilly00]

Trying to send mail from me to myself using yahoo mail on win 10 laptop
Date time stamp on PC is correct

I can send mail from my email address to my email address using yahoo mail.

Installed XAMPP 8.2.4 from sourceforge
got Error message
server certificate does NOT include an ID which matches the server name
Changes made
In xampp/apache/conf/extra/httpd-ssl.conf commented ServerName www.example.com:443 out and added ServerName localhost and restarted apache it worked

Made changes to Sendmail [/b]

; you must change mail.mydomain.com to your smtp server,
; or to IIS's "pickup" directory. (generally C:\Inetpub\mailroot\Pickup)
; emails delivered via IIS's pickup directory cause sendmail to
; run quicker, but you won't get error messages back to the calling
; application.

; if your smtp server uses pop3 before smtp authentication, modify the
; following three lines. do not enable unless it is required.

Dont ask here, ask Yahoo. Its their SMTP Server which rejects your email. Many Email Providers rejects Email from private IPs (due to SPAM problems). Or maybe Yahoo requires certain crypts (SSL / TLS). As i said: ask Yahoo. We cannot know, what Yahoo requires.
