Hi, cheers for your response, however as Michael pointed out, such a server |
| 8 |
would be unnecessary. I wasn't aware of the S.M.T.P.\ standard which mandates |
| 9 |
M.T.A.s retry for four or five days, and given that my server won't be down for |
| 10 |
longer than a few minutes, I think I'm going to stick with a single MX. |
