We have just been hit by a spammer who successfully sent junk mail to our list of 5000 subscribers. The e-mail From field shows our Listserv admin account which was not an account that was even identified in the list's configuration file. The configuration was set to Send=Private (so no non-subscribers could post) and Default-Options=NOPOST (so no subscribers could post). We thought this meant that only the owner could post but of course didn't predict that someone could "forge" this address or the admin address and send an e-mail. We have since changed the Send parm to Send=Editor,Hold,Confirm. I've tried a number of tests and this setting seems to do the trick, but I wanted to poll this group to get recommendations on other settings that might be set, keeping in mind that we send out broadcasts about once a month and don't want it to be a painstaking, high maintenance activity. Note also that the list is re-generated through a bulk-load process. Subscribers cannot subscribe or change their settings, so it seems that the Validate parm is not as critical as would be the case if subscribers were allowed to manage their accounts. The current configuration looks like this: Subscription= By_owner Ack= Yes Confidential= Yes Validate= No Reply-to= [log in to unmask] Review= Owners Editor= xxxxxx @pharmacists.ca Send= Editor,Hold,Confirm Errors-To= Owner Owner= xxxxxx @pharmacists.ca Default-Options= NOPOST Notebook= Yes,e:\sites\listserv-cpha.inf.ca,Monthly,Owner Change-Log= Yes Also, we are trying to determine who the spammer is and how they managed to send this e-mail. Does anyone have any experience in this area? The manager of our Listserv says there was a virus that generated the e-mail but it's still not clear how a virus could find the admin account to post to this list. Any ideas? Thanks in advance. ...Wes =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~= Wes Anderson, Wescath Solutions per Canadian Pharmacists Association Tel: 613-523-7877 ext. 228 CPhA: [log in to unmask] <mailto:[log in to unmask]> =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=
