Re: [qmailtoaster] re Invalid rcpthosts client email addresses sending emails to other rcpthosts clients
Hi Martin, Found a big downside to it! Clients using their mobiles for email sending can no longer send from their mobile isp smtp server. Bugger thought I had it beat as well. On 17/11/2010 6:43 PM, Martin Waschbuesch wrote: Cool! Let us know whether it has any impact. The upside to this is that it will be harder for spammers to use your addresses to send to other domains as well - although it is of course possible to spoof the ip, too. At any rate I hope this works out for you!

I had used the old spf web utility to create the record you saw. It would appear that that site is now the OLD one and the new one does in fact do things differently now. Thank you for your help, I have changed a single domain as of now to test it before changing them all. The site http://old.openspf.org/wizard.html, if you have time to look at it, does offer only the ~all option and if I had read the final page fully it proves you are absolutely correct with your assessment.
