RE: [PHP] mail() with mailing lists problem

True. I had the attachment outside of the function (encoding once) but this is a leftover of debugging and trying to get it to work. I hadn't thought of Bcc-ing everybody. I'll try that, thanks. Still doesn't solve the problem, though. Maybe a socket is the answer. -----Original Message----- From: TD - Sales International Holland B.V.

This way you are MIME-encoding the attachment over and over which consumes a lot of resources. MIME-encoding a 10MB file will suck up a P-III 600 for 20 to 30 secs or so depending on other background processes and diskspeed. MIME encoding the same attachment a 1000 times doesn't appear really fast to me. Also, with all the headers you use, you could just as well open a socket to the SMTP service, then you could have additional error checking I guess.......
