Hi,

when we open this morning zoho mail this error appears on screen

"security certified not valid for this server, change input port for 110 and try again"

we try to change the 995 pop port to 110 and doesn´t work.

and when we try to send an e-mail this error appears two:

"sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
