70033 An e-mail cannot be sent because a TCP/IP

This system alarm is generated only at the first
attempt. All subsequent unsuccessful attempts to
send an e-mail will no longer generate a system
alarm. The event is regenerated when an e-mail
has been successfully sent in the meantime.
The central e-mail component in WinCC flexible
Runtime attempts, in regular intervals (1 minute), to
establish the connection to the SMTP server and to
send the remaining e-mails.
Check the network connection to the SMTP server and
re-establish it if necessary.
70034 Following a disruption, the TCP/IP connection to
the SMTP server could be re-established.
The queued e-mails are then sent.
