I would like to set up a client with php newsletter software. I have run into countless problems doing this on other server environments. I have tried to make my questions exact.
Should I be using the php sendmail mail transfer agent or is it preferred that I speak directly to your stmp server over sockets?
I realize there is load balancing on your server ( Thank God ) are there any other restraints in place that will terminate my mailing scripts prematurely outside of the usual max_execution time settings?
In other words... should I be scheduling controlled bursts with cron or can I get away with letting loose and just send everything out all at once?
My clients current mailing lists do not exceed 6,000 - 8,000 emails addresses. Most clients are under 500 emails total.
Will I be billed additionally for mail traffic?
Any help would be much appreciated.
