I have a newsletter script (people have to sign up themselves to be sent this newsletter) running on my university's server. The script sends a MIME e-mail to about 150 addresses and is for a student sport association. We have sponsors whose logo's we agreed to put on the newsletter.
Before we had the sponsors, I used to send it to these addresses without any problems. But since I put the logo's in the newsletter these mails started getting spam-level 5 from the spam-filters of my own university and also from Hotmail so the subject line would be changed to *****SPAM***** Newsletter. Of course, we don't want this.
The script is a PHP script which uses a Mysql database to get the e-mail addresses and it loops until it has sent an e-mail to all addresses.
What do I have to change? Do I have to talk to the association running the student server?
Thanx in advance,
