I totally agree with you, 5 seconds is way too short.
Here is what I am trying to achieve:
I open the connection using mail_open, do couple IMAP operations like
fetching new mail. Everything goes well as expected.
I am done for know but I keep the IMAP connection open for performance
purpose. 30 seconds later, I execute a another IMAP command but the
connection did drop since last time I used it therefore the command
failed! Personally, I would like to be able to detect if my connection
is still alive before executing any IMAP command, if it's not open, I
can try to open it first.
The simplest solution to that problem is to always call mail_open before
doing anything rather than "holding" the stream but this solution as
performance issue. Would it be another better and more elegant way to
achieve that?

mail_ping() is, indeed, the correct way to determine is a stream is
alive. The only way to know if a stream is still alive is to use it.
5 seconds is, however, a rather small interval. I recommend at least
60 seconds, and more commonly 150 seconds. In fact, you want to do
this in order to get new mail notifications.
