Mail Routing Question

for aaa.com and it "needs" to be changed to elsewhere. I somehow seem to recall that there are some MTAs that do not use the MX records, but only check the A records. Will changing the A record for aaa.com cause the loss of some incoming mail? -- Doug

Re: Chinese Spam

Thanks. I went with: IF /^Message-id:/ /@qq\.com/ Reject ENDIF It's not all that pretty, but it works fine. I have been watching the logs and those messages are now being rejected. Thanks for all the help. -- Doug > On 7 September 2017, at 15:50, pgndev <pgnet@gmail.com&

Re: Returning an Error Response

Thanks for the pointers on that. I spent a couple days digging around and never found it. On 6 July 2017, at 12:06, /dev/rob0 <r...@gmx.co.uk> wrote: > > > On Thu, Jul 06, 2017 at 11:45:01AM -0700, Doug Hardie wrote: >> When using virtual domains, > >
