Hello everyone, I've recently upgraded from Win2k+Xmail 1.25 to RHEL5.5 + Xmail 1.27. This is also on a new hosting provider in a new city. So much has changed. I used to be able to send to this person @ dinglepartners.com.au However now I get error 256. Immediately I assumed there was a DNS issue and did a manual DIG and checked the DNS settings. They all seem fine, so here I pose the question to you all in case I missed something. Below is all the detail I gathered in my checking. It looks like the A-Record is being favoured over the MX, but I know that Davide did some work on the DNS resolver in recent versions to improve the DNS logic. Does anyone have any ideas. Much appreciated. Rob :-) *** SLOG partial ***************************** [PeekTime] 1295882102 : Tue, 25 Jan 2011 02:15:02 +1100 << ErrCode = -256 ErrString = Remote DNS server failed SMAIL SMTP-Send EDNS = "dinglepartners.com.au" SMTP = "aaaaa.com.au" From = "[email protected]" To = "[email protected]" Failed !
