Yes. Look at http://www.sendmail.org/ for instructions on how to fight off SPAM attacks on your sendmail-based SMTP server. Also, http://spam.abuse.net/spam/ for related info. Your ISP should configure their sendmail (or whatever mailer they use) to not accept mail from non-subscribers, instead of cutting everyone off. In fact, how do they propose that their customers send mail? > How about using POP3 to send email? My personal NNTP provider gives > me an email account and this is what they use. You use POP3 to retrieve mail, not to send mail. -jav To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
