SPF wins over Sender ID

Finally, Sender ID (Microsoft's patented technology to assist SMTP authentication) seems really dead at the IETF; The winner seems to be either SPF or SPF unified.

SPF online tutorial

For those technically inclined, I found an interesting and thorough tutorial at http://www.zytrax.com/books/dns/ch9/spf.html. Good reading.

Why publish an SPF record?

In short, SPF allows to check - as Hotmail does now - that an email claiming to come from you is not a scam. It is not 100% guaranteed, but publishing an SPF record for your company domain or your own domain you protect your reputation.

Your réputation is probably worth a few minutes of small work.

News of SpamAnti.net

SpamAnti.net is SPF-compatible

In order to stick to current technology developments, I declared a record for the spamanti.net domain allowing automatic authentification of emails claiming to come from my domain.

The tools I had to use were easily available:

• The PObox wizard
• The DNSstuff tester
• Domain Information Groper, for DNS checking
• online dig, for DNS checking

It may be useful in your own drive to repel SPAM. You can easily do the same for the domains you manage. It is fairly simple.

Beware CJB.net

This information is for you if you just came to this site through the old SpamAnti.cjb.net address. I learned that this free redirection service (that I used primarily before I got my own domain years ago), on top of allowing a simple web address (like SpamAnti.cjb.net) inserts advertisements.

Up to this, it's ok. But a few real crooks use this possibiltiy to force install a Precision time utility program that is actually a spyware from the GAIN/gator family.

If you came here through this old address, here is my advice:

• Start by removing the old address from your bookmarks and always use http://www.spamanti.net/en/ that is the only operating address from now on.
• You should also remove the Gator spyware from your system if it was able to install itself. Apparently, Ad-Aware from Lavasoftusa.com and SpyBot are able to do this removal and exist in free versions.

In any case, I immediately stop the redirection by cjb.net (I do not want to help distribute a spyware). Start using http://www.spamanti.net/en/.

I am sorry for this significant inconvenience it could have cause to some of my visitors.
