I have a Mailman list that contains a number of addresses at a major ISP that lists 7 MX hosts. When delivering mail to addresses at that ISP, all the MX hosts but one readily accept the mail. That one recalcitrant host soft-rejects (gray-lists) mail for about 1 hour.
Is there any way to configure Postfix to not even try the one reluctant MX host for that domain? -- Jim Garrison ([EMAIL PROTECTED]) PGP Keys at http://www.jhmg.net RSA 0x04B73B7F DH 0x70738D88
