I have a message box saying "mail can't verify the identity of the server "smtp.tools.sky.com". " the certificate for this server is invalid. You might be connecting to a server that is pretending to be "smtp.tools.Sky.com" which could put your confidential information at risk. Would you like to connect to the server anyway?" &nbsp;It then shows a "tree" with the root server being Sectigo Public Server Authentication Root 46 and says this certificate is not trusted. Under this is CA OV R36 with smtp. tools.sky.com underneath. &nbsp;Is this okay to connect to?&nbsp;</P> Thu, 09 Jul 2026 08:39:04 GMT https://helpforum.sky.com/t5/Email/Outbox-won-t-send-emails/m-p/5315161#M109820 Jeanette67 2026-07-09T08:39:04Z https://helpforum.sky.com/t5/Email/Outbox-won-t-send-emails/m-p/5315172#M109821 <P><a href="https://helpforum.sky.com/t5/user/viewprofilepage/user-id/4726539">@Jeanette67</a>&nbsp;</P> <P>Does changing it to&nbsp;<STRONG>smtp.mail.yahoo.com</STRONG> allow it to works ?</P> Thu, 09 Jul 2026 08:48:19 GMT https://helpforum.sky.com/t5/Email/Outbox-won-t-send-emails/m-p/5315172#M109821 caesarome 2026-07-09T08:48:19Z
