Hi,
In other terms, they seem to be one of the few providers who neither do DKIM nor SPF currently, which is also interesting...
on https://postmaster.t-online.de/#t3.5 they tell they don't use SPF, butt-online.de. 86400 IN TXT "v=spf1 ip4:194.25.134.16/28 ip4:194.25.134.80/28 ~all
Maybe they also would get issues to deliver mail to gmail etc? Regards Bjoern _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
