[I offer the following *as is* w/ no further explanation. I had recently sent this to another correspondent.] >help me out. What kind of anti-virus setup are you using to scan >messages and attachments arriving at your LISTSERV for distribution? -- First and Foremost, we use LISTSERV(R) brand mailing list management software. We have configured it (relative to security) as such, which allows us to better ameliorate spam and virus/worms: ADMINISTRATION of USA Financial Aid Offices Subscription= Open,CONFIRM Reply-To= SENDER,Respect Confirm-Delay= 71 h Send= PRIVATE Confidential= No Review= owner Validate= NO Language= NOHTML Attachments= No Default-options= Repro,Short,Review Filter= Also,*postmast*@*,*postmstr*@*,*maiser*@*,*nobody*@* Renewal= 3-monthly,Delay(7),Probe Sizelim= 200 This translates into: One must subscribe in order to be allowed to post to the list One can only subscribe by going through a process: customer "asks" our software to subscribe, our software acknowledges that request by returning a pseudo random number to the requester, the requester returns that PRN back to our software and is successfully subscribed Subscribers can not get a list of other list subscribers, unless the latter post to the list List does NOT permit non-text attachments e.g., NO .WDP, .EXE, JPG, .XLS, .VCARD We limit per message size to 200 lines List distributions "default" REPLY-TO: the poster, and not the list (this isn't fool-proof) New subscribers are automatically moderated, though by manual intervention, we do turn off moderation for all .EDU subscribers; all others must "prove" themselves (within our target audience) in order to post w/o moderation Multiple list-owners are defined and we encourage the use of the generic list-owner address of [log in to unmask]; list-owners coordinate their activities so that mail to the generic address is answered a timely fashion One of its "secondary" features is an inter-connected network of peered (list) servers and it maintains an anti-spam feature among themselves, as close to real-time as a store-n-forward network will allow. Our institution has both centralized and distributed security, information, and network offices/personnel. We highly encourage, and provide licenses (some no-charge, others costs) and WEB sites for A/V software.
