[Alpine-info] spam on alpine-info

[Lucio Chiappetti via Alpine-info]

Eduardo,
         do you have administrator authority on 
alpine-info at u.washington.edu ? Can you implement some antispam filtering 
on fictitious new subscribers ? Or pass this suggestion to the 
admistrator?

I receive the list in digest mode, so it is not much of a nuisance, but in 
the last days my digest included three obvious spam messages from an 
otherwise unknown user.

Some mailing list force moderator approval on new subscribers. and that 
wpould be enough to ban spammers.

Thanks
