When the Encryption Desktop client detects that network access is available but there are issues due to wi-fi negotiation, VPN tunnel startup or other transitory issues, email messages that are attempting to be delivered fail.
A message from System Administrator is received containing this error:
Your message did not reach any of the intended recipients.
Message delivery failed. Please check PGP log for details.
Temporary network issues result in email being undeliverable.
