Sorry for getting off-topic .. but... 23:59:60 is the same (if wold exist) like 00:00:00 and this is the New year... No: 23:59:60 is not the same as 00:00:00 http://hpiers.obspm.fr/eoppc/bul/bulc/bulletinc.dat So 31.12.2008 will be 86401 seconds long instead of 86400 seconds. But anyway..

Filtering locally simply means stopping end users to access illegal sites. Ok, but the sites are still there and everybody else will still have access ! Yes, but i'm sure that the 'local' netclean box can log IPs of people who attempted to access such illegal sites (such as Wikipedia) So

Hi Roger, Now we found out that bluewin doesn't allow authenticated smtp-relay from users outside their ip-range, so all our customers with bluewin-mailadresses would have no smtp-server available. That's not entirely correct: smtpauth.bluewin.ch will relay mails from non-bluewin-ip-ranges

Hi, Thank you for clearing this up. So we have to give bluewin-users with free bluewin mail-accounts an smtp-account on our servers I think. Well, they could call our helpdesk and ask them to disable the 'Restricted IP-Range' feature for a specific mailaccount. Our helpdesk will disable it

It's a little expensive if you have many SMS'es - does anyone know who to contact (e.g. at Swisscom) to get a package-deal with a direct TCP interface? You are looking for an 'SMSC Large Account' http://www.swisscom-mobile.ch/scm/gek_sms_large_account-de.aspx You'll get your own 'short id'

Seems to me that the benefit of cutting down on Spam would be worth the trouble of using port 587... Blocking port 25 is just a quick-n-dirty 'fix'. What will happen when virus-writers are going to spam using 587 (The credentials are stored on the users PC anyway..)? What would people do to

would they not then block official port 587 as well as port 25? That was the position I heard the 'customer service rep' take the last time I tried to solve such a problem through appeal to bureaucratic sensibility. There isn't really a (valid) reason to block port 587: Blocking outgoing

And why not using the existing authentication protocol on outgoing smtp server ? So the sender can use the smtp server of the provider of its email address from any network and SPF can work without any problem. How would this solve the forwarding problem? And how are you going to teach
