Hi, I have a client that has about 17000 clients on his mailing list. The addresses are all in a mysql table and currently he is attempting to send it all with a php routine, but that causes the mail system to crash as php tries to send all 17000 at one time... Waht I ned is a perl routine that can wait a while after each batch of xxx (what are your suggestions?) and even to keep an eye on the system load and not to send anything unless the system load is below yyy (again, what is a good value?). I would ideally still want to incorporate php in this in parts, maybe to get the addresses from the mysql table and then write them to a text file where perl can read them and then send the mail...
Can someone give me an example of how to do this, it's rather urgent.
Server = linux redhat 7.0 with latest patches etc.
