There appears to be an option in the standard configuration to check SPF records by enabling the CHECK_RCPT_SPF macro and loading the libmail-spf-query-perl package. I''m considering doing this, however I''m worried about mail that gets relayed through my backup MXs. I''m worried that some of that mail will get wrongly flagged as failing the SPF tests. I don''t want to enable SPF & have that mail bounce. Do I need to modify 30_exim4-config_check_rcpt to have it accept mail from my backup MXs without the doing the SPF checks? -- Alex King Linuxworks Phone: +64 3 473 1611 Mobile: +64 21 410 420
