how to make qmail to send remote mail at particular time

[Milen Petrinski]

Hi everybody,   I have Linux system with qmail and vpopmail installed, which connects to the Internet throu ppp. I read in "Life with qmail" that qmail processes every message individualy and I found that remote messages stay in the queue too long, even worse, it is possible a message not to be send at all.   How can I make qmail to try to send remote mail when ppp ling comes up?   In the mailing list archive I read something about sending the remote mail in maildir and using maildir2smtp when ling comes up, but how to make this to work with vpopmail?   Thank you,   Milen Petrinski
