Not necessarily, unless it gets to the point where it starts to fill up your disk partition. What that message usually indicates is a NULL sendmail connection, ie. the remote (see below) host connected to port 25 and initiated the connection but did not then send any further data; or it opened the connection, issued EHLO/HELO and then didn't send any further data. This can be symptomatic of a few things, the most common (in my experience) is an overloaded or badly configured remote server. I would contact the remote server admins, personally, and discuss it with them first. It's not a security issue.
