I have a problem that's driving me nuts.... I'm trying to send mail via SMTP/sockets.
Some of the data I send to the socket repeats itself, and I have no idea why. "You are repeating something!", I hear you say, but I'm fairly sure I'm not. I've echoed what is sent to the SMTP server below.
Notice I've used NOOP once which returns OK, but in the socket response it comes up twice! What am I missing? The mail comes through fine, but the server gives up if you repeat this because of too many errors, so I can't email a bunch of people at once. I'm using Sendmail 8.9.3, PHP Version 4.0.1pl2, Linux, and I've used some code from 452Productions.com. I've even tested the orginal code, which does the same thing.
Any insight much appreciated...
