Too bad xmail doesn't have natively spf-support yet, many other mailers do: http://www.openspf.org/Implementations Here's a description of my solution of SPF with xmail: I tried to use the xm-spf.pl, but perl reported some errors about a missing component or so. Then I found a package named "spfquery" in the Debian repository, it's an executable (or maybe just a perl script?). So I managed to write a small filter programm (for filters.pre-data.tab) in C/C++, and from within that I'm calling the spfquery program with the right parameters. This works well. I can recommend it. It needs just 3 parameters (all supplied by xmail to the filter), like so: spfquery --ip=x.x.x.x --mfrom=u...@example.com --helo=hostname.com and returns a few lines where the first is the status, like "pass", "fail", "softfail" etc. For more info one should consult the man page of spfquery. But: one has to do some reformatting of the params, for example stripping off the braces from the ip "[x.x.x.x]" And here is an spf tester: http://www.kitterman.com/spf/validate.html Hope this info helps others wanting to add SPF-protection to their xmail server. But beware: this stuff is IMHO very advanced stuff, one needs some experience with DNS records, and some experience in writing a filter, ie. programming. So, my advice: if possible just hire someone who already has experience in this stuff and xmail. cu uenal Edinilson - ATINET wrote, On 05/21/2013 09:26 PM: > Below a message from Davide about SPF: > > ------------------------------------------ > On Thu, 29 Jan 2009, Ralf wrote: > >> I'm trying to switch from qmail to xmail. >> There I had SPF activated and would like to use SPF also in xmail. >> I saw that there is a perl script for SPF >> (http://www.xmailserver.org/xm-spf.pl), >> but how do I integrate it into xmail? > > Suggestion.

True there is a way to make SPF work. As far as I know, the admin has to devise a small script and make sure it is added in the companys DNSs on the MX record for the server. Something like this : "v=spf1 ip4:IP.ADD.RE.SS/32 mx ~all" However, SPF never actually delivered what it promised.
