The remote certificate is invalid according to the validation procedure SMTP NAV

Hi All,

The remote certificate is invalid according to the validation procedure

The above error may come while sending mails through SMTP in NAV.

The reason may be you have setup Secured Connection in SMTP setup in NAV, while the SMTP Server doesn't have valid certificate to accept the secure connection.

You can  install a valid certificate on Server or you can untick Secured Connection in SMTP setup to connect with unsecured connection.

NAV Approval Mail SMTP Send as permission Error

Hi All,

SMTP Send as Permission Error comes if the user sending the Approval Mail does not have Send as Permission on Mail Server.

If the SMTP user is different than the one sending the mail then this permission is needed.
