Getting MessagingException Failure from PutEmail Processor

[#1]

Hi,

I am getting failure in PutEmail Processor in our organization's nifi server.The error states that "Could not convert socket to TLS:routing to failure: javax.mail.MessagingException: Could not convert socket to TLS:
nested exception is:
javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake"

I routed the failure relation back to processor and after 30-40(randomly) or more retries it processes successfully.Though trying to figure out why its getting failure in first place.

Attaching the log here.
