For decades (since early 1990's) I've operated LISTSERV (R) lists,
filtering out all attachments (perhaps not inline text).
Recently, this has come under review by a subscriber who feels that
this is too restrictive.
Personally, as list-owner, I feel that not allowing attachments has
served us well: minimum spam (spoofed senders), no viruses, no
redundant attachments in recipients' mail boxes (which has to be
dealt with on a per-subscriber basis), no question about currency of
attachments e.g., documents, no lengthy email controlled by
SIZELIM=) especially with REPLY. Minimum size NOTEBOOKs.
So if you do allow attachments, how do you control for viruses,
perhaps authorized senders (via perhaps sub-list/super-list where
the super-list has attachments, and authorized senders). Are you
satisfied with this, especially with heterogenous mail client (MUA)
/ host environments?
The particular list in question does have its own fileserver w/ its
own authorization and controls.
Thank you for any advice especially gotchas.
