I can confirm such behaviour, thus here it's not that heavy like the end of last year. Any catch-all is horrible in such cases. In my opinion, this is tactically used to 'find' valid email addresses for later use. But no proof of that.

Sure, you don't want to receive _any_ email? You will get rid of a lot of customers like that, Daniel. You rather limit the connection per host simultanously and - if possible - add more mx servers. Graylisting possibly helps as well. Cheerz - Dan _______________________________________________ swinog mailing list [email protected] http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
