<p class=MsoNormal><font size=3 face=Rockwell><span style='font-size:12.0pt;
font-family:Rockwell'>Due to a recent incident of a public wireless user
sending spam, we are looking at what ports and applications we can comfortably
make available for use on our public wireless network and which one may need to
be blocked. Specific to the spam problem, we are curious as to what other
libraries are doing about public access to SMTP port 25. Do you allow it or
block it? We are implementing a public logon page that requires the user to “accept”
our public acceptable use policy but of course that’s just a check
box and doesn’t stop the user from mischief after “accepting”
the rules.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face=Rockwell><span style='font-size:12.0pt;
font-family:Rockwell'>I would think that with web access to Gmail, Hotmail,
Outlook Web Access, IMAP, and POP3 that the client mail issue would be
sufficiently covered for the serious business user who needs to access mail
while doing some work at the library. Blocking port 25 would only stop a patron
from running a full-fledged mail server over our network and I can’t see anyone
wanting to do that on a wireless laptop. That’s just my own view however
and I could well be overlooking valid reasons for leaving port 25 open. The
question is then, what are other libraries doing? How are you controlling
public wireless access and what application ports do you leave open? Is this
sort of thing causing anyone any grief? I would very much appreciate
suggestions, recommendations, horror stories, or success stories.<o:p></o:p></span></font></p>
