verify=CAFail, verifymsg=unable to get local issuer certificate

[salon442]

For outgoing mail we are facing verify=CAFail, verifymsg=unable to get local issuer certificate issue in fortimail.

Our scenario is exchange server>fml>outside..no issue in incoming email but issue only in outgoing email..we are getting bounce back for outgoing email and  email are not delivering to recipient.

What can be done to solve verify=CAFail issue in fortimail v6.4.3.

Should we upload the CA certificate of exchange server in fortimail certificate?

Loading the CA certificate of exchange into the FML should help with the verify=CAFail messages but that's likely not the issue with your outgoing mail. What do the bounceback messages say?
