530 5.7.0 Must issue a STARTTLS command first
I have an Exchange server located in my DMZ that is being used for popS and smtpS mail connections. I renewed the certificate on the server via IIS manager and after doing this my pop and smtp were no longer working. I went into exchange manager and drilled down to the pop3 and smtp protocols and replaced the current cert with the new cert I installed via IIS. After doing this pop started working again and I can receive over smtp, but sending over smtp I get the following error '530 5.7.0 Must issue a STARTTLS command first'. I have tried renewing the cert again but still not working. Has anyone seen this before and know what I may need to do to resolve this issue?
