or down-/upgrade to 8.9.3, my current potato 8.9.3-21 isn´t vulnerable to this (or to any other from http://www.abuse.net/relay.html) relay attack. another option would be to check out sendmail.org´s excellent faq...there are anti-relay rulesets for every sendmail from 8.6 to 8.8 IIRC (from 8.9 on they´re built-in). of course, you could always to choose to bypass sendmail for incoming connections, the obtuse smtpd http://www.obtuse.com/smtpd.html is my favourite choice for somesuch (although partly for it´s aggressively amusing messages ("host.bla.com is thrilled beyond bladder control to meet you") *g*). hth, &rw -- / Robert Waldner <[EMAIL PROTECTED]> | Phone: +43 1 89933 0 Fax x533 \ \ KPNQwest/AT tech staff | Diefenbachg. 35 A-1150 Wien /
