Ok, I'm back up and rolling again. Thanks Matthew, and the others who replied off-list for all of the feedback. One thing that I forgot to ask in my original post was that of clustering. In our production network, we have a cluster of perimeter MX's, and a similar setup for our submission boxes (it's been a couple of years since we've strictly enforced AUTH for all clients). What I don't have, and have always wondered about, is live redundancy for the IMAP/POP services. I know that this would be a challenge to some degree considering the high volume of data changes. Perhaps a carp(4) setup between a couple of MDA's, where when the primary is up, a constant rsync pushes the data to the backup. Or perhaps a combination of rsync for manual changes, and a method to have the primary write the emails to a local disk, and a network disk simultaneously? If anyone has a setup that has redundancy for their IMAP/POP services, and a method to keep the changing data relatively up-to-date, I'd love to hear about it. Cheers, Steve --------------ms010901000904060906070503 Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="smime.p7s" Content-Description: S/MIME Cryptographic Signature MIAGCSqGSIb3DQEHAqCAMIACAQExCzAJBgUrDgMCGgUAMIAGCSqGSIb3DQEHAQAAoIII/zCC AtowggJDoAMCAQICEEs5xg/J3t77QWJ4SatV1HcwDQYJKoZIhvcNAQEFBQAwYjELMAkGA1UE BhMCWkExJTAjBgNVBAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAqBgNVBAMT I1RoYXd0ZSBQZXJzb25hbCBGcmVlbWFpbCBJc3N1aW5nIENBMB4XDTA5MDUwNzIzMTYxMFoX DTEwMDUwNzIzMTYxMFowQjEfMB0GA1UEAxMWVGhhd3RlIEZyZWVtYWlsIE1lbWJlcjEfMB0G CSqGSIb3DQEJARYQc3RldmVAaWJjdGVjaC5jYTCCASIwDQYJKoZIhvcNAQEBBQADggEPADCC AQoCggEBAJSTRAjP1RVa87/mnZn+PBTbENgyhhBJ4rWApmaNcthzRdk2DB/49KrXx3EQP60w Lj4KU0DFkiGNVj9BnVxRAx/WDXKxGC3uGGEG6gjyWv8KFMWMsH9mL7y7uNow1HueT6pZUf9o yY8Ewd+01QpGi7FfXOae7lGHhbEwnEJGwz08ytRfLmH0KtEzlZanZZhwDGX5s1kIHnyxdACh 3byXY6Z2bOrx0rcrQHCnHJppxddR60F7igjaMuBFstE51h9XTgXDNKJbglqTug5ghGihNuP6 VsBN7ue62y96UGIE22TvKEcAQ665vQGjHqZeSzZYy+hWNOa27pWFmhlqFjx0x8MCAwEAAaMt MCswGwYDVR0RBBQwEoEQc3RldmVAaWJjdGVjaC5jYTAMBgNVHRMBAf8EAjAAMA0GCSqGSIb3 DQEBBQUAA4GBAMOmjxjp2Xzk6ZHLwTgFDzVhm98RjRT3UXotKjNIR7SgwfWF5wkJrx4I+dXu ui5ztMEq4bTTRgJ344MqE6uZiZlg+tBIFHZGCJfKdzsX4QuV2jmw0sR5dMaYxG6tlDB0YUMv gTqzV7ZDpiusTMOZe9pP1PdxFhOcIJXtMQDj5LhuMIIC2jCCAkOgAwIBAgIQSznGD8ne3vtB YnhJq1XUdzANBgkqhkiG9w0BAQUFADBiMQswCQYDVQQGEwJaQTElMCMGA1UEChMcVGhhd3Rl IENvbnN1bHRpbmcgKFB0eSkgTHRkLjEsMCoGA1UEAxMjVGhhd3RlIFBlcnNvbmFsIEZyZWVt YWlsIElzc3VpbmcgQ0EwHhcNMDkwNTA3MjMxNjEwWhcNMTAwNTA3MjMxNjEwWjBCMR8wHQYD VQQDExZUaGF3dGUgRnJlZW1haWwgTWVtYmVyMR8wHQYJKoZIhvcNAQkBFhBzdGV2ZUBpYmN0 ZWNoLmNhMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAlJNECM/VFVrzv+admf48 FNsQ2DKGEEnitYCmZo1y2HNF2TYMH/j0qtfHcRA/rTAuPgpTQMWSIY1WP0GdXFEDH9YNcrEY Le4YYQbqCPJa/woUxYywf2YvvLu42jDUe55PqllR/2jJjwTB37TVCkaLsV9c5p7uUYeFsTCc QkbDPTzK1F8uYfQq0TOVlqdlmHAMZfmzWQgefLF0AKHdvJdjpnZs6vHStytAcKccmmnF11Hr QXuKCNoy4EWy0TnWH1dOBcM0oluCWpO6DmCEaKE24/pWwE3u57rbL3pQYgTbZO8oRwBDrrm9 AaMepl5LNljL6FY05rbulYWaGWoWPHTHwwIDAQABoy0wKzAbBgNVHREEFDASgRBzdGV2ZUBp YmN0ZWNoLmNhMAwGA1UdEwEB/wQCMAAwDQYJKoZIhvcNAQEFBQADgYEAw6aPGOnZfOTpkcvB OAUPNWGb3xGNFPdRei0qM0hHtKDB9YXnCQmvHgj51e66LnO0wSrhtNNGAnfjgyoTq5mJmWD6 0EgUdkYIl8p3OxfhC5XaObDSxHl0xpjEbq2UMHRhQy+BOrNXtkOmK6xMw5l72k/U93EWE5wg le0xAOPkuG4wggM/MIICqKADAgECAgENMA0GCSqGSIb3DQEBBQUAMIHRMQswCQYDVQQGEwJa QTEVMBMGA1UECBMMV2VzdGVybiBDYXBlMRIwEAYDVQQHEwlDYXBlIFRvd24xGjAYBgNVBAoT EVRoYXd0ZSBDb25zdWx0aW5nMSgwJgYDVQQLEx9DZXJ0aWZpY2F0aW9uIFNlcnZpY2VzIERp dmlzaW9uMSQwIgYDVQQDExtUaGF3dGUgUGVyc29uYWwgRnJlZW1haWwgQ0ExKzApBgkqhkiG 9w0BCQEWHHBlcnNvbmFsLWZyZWVtYWlsQHRoYXd0ZS5jb20wHhcNMDMwNzE3MDAwMDAwWhcN MTMwNzE2MjM1OTU5WjBiMQswCQYDVQQGEwJaQTElMCMGA1UEChMcVGhhd3RlIENvbnN1bHRp bmcgKFB0eSkgTHRkLjEsMCoGA1UEAxMjVGhhd3RlIFBlcnNvbmFsIEZyZWVtYWlsIElzc3Vp bmcgQ0EwgZ8wDQYJKoZIhvcNAQEBBQADgY0AMIGJAoGBAMSmPFVzVftOucqZWh5owHUEcJ3f 6f+jHuy9zfVb8hp2vX8MOmHyv1HOAdTlUAow1wJjWiyJFXCO3cnwK4Vaqj9xVsuvPAsH5/Ef kTYkKhPPK9Xzgnc9A74r/rsYPge/QIACZNenprufZdHFKlSFD0gEf6e20TxhBEAeZBlyYLf7 AgMBAAGjgZQwgZEwEgYDVR0TAQH/BAgwBgEB/wIBADBDBgNVHR8EPDA6MDigNqA0hjJodHRw Oi8vY3JsLnRoYXd0ZS5jb20vVGhhd3RlUGVyc29uYWxGcmVlbWFpbENBLmNybDALBgNVHQ8E BAMCAQYwKQYDVR0RBCIwIKQeMBwxGjAYBgNVBAMTEVByaXZhdGVMYWJlbDItMTM4MA0GCSqG SIb3DQEBBQUAA4GBAEiM0VCD6gsuzA2jZqxnD3+vrL7CF6FDlpSdf0whuPg2H6otnzYvwPQc UCCTcDz9reFhYsPZOhl+hLGZGwDFGguCdJ4lUJRix9sncVcljd2pnDmOjCBPZV+V2vf3h9bG CE6u9uo05RAaWzVNd+NWIXiC3CEZNd4ksdMdRv9dX2VPMYIDZDCCA2ACAQEwdjBiMQswCQYD VQQGEwJaQTElMCMGA1UEChMcVGhhd3RlIENvbnN1bHRpbmcgKFB0eSkgTHRkLjEsMCoGA1UE AxMjVGhhd3RlIFBlcnNvbmFsIEZyZWVtYWlsIElzc3VpbmcgQ0ECEEs5xg/J3t77QWJ4SatV 1HcwCQYFKw4DAhoFAKCCAcMwGAYJKoZIhvcNAQkDMQsGCSqGSIb3DQEHATAcBgkqhkiG9w0B CQUxDxcNMDkwOTE2MTMzNDUxWjAjBgkqhkiG9w0BCQQxFgQU9DBUoF96Unaza82vq86MNtjc iPgwUgYJKoZIhvcNAQkPMUUwQzAKBggqhkiG9w0DBzAOBggqhkiG9w0DAgICAIAwDQYIKoZI hvcNAwICAUAwBwYFKw4DAgcwDQYIKoZIhvcNAwICASgwgYUGCSsGAQQBgjcQBDF4MHYwYjEL MAkGA1UEBhMCWkExJTAjBgNVBAoTHFRoYXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAq BgNVBAMTI1RoYXd0ZSBQZXJzb25hbCBGcmVlbWFpbCBJc3N1aW5nIENBAhBLOcYPyd7e+0Fi eEmrVdR3MIGHBgsqhkiG9w0BCRACCzF4oHYwYjELMAkGA1UEBhMCWkExJTAjBgNVBAoTHFRo YXd0ZSBDb25zdWx0aW5nIChQdHkpIEx0ZC4xLDAqBgNVBAMTI1RoYXd0ZSBQZXJzb25hbCBG cmVlbWFpbCBJc3N1aW5nIENBAhBLOcYPyd7e+0FieEmrVdR3MA0GCSqGSIb3DQEBAQUABIIB AFSBYzly9whEVTbEnx12f9gzD4teS0r8N0bH5v6Av0lS2zEWUPWSXfp/HCVIj+ja6JY5MhT8 VTamBS2xP5hldVIJaZkQIvEGUNsHoLIUgQ2B5BR7nowTA5QPnn3VR2e7z+eG1mDtW9ufO2tW wV0TYcb9rq9LlJq139Xdmsf14BXk44eUL+2DdWcCK+UCF3iKJLXLD46htpQ6rkzFWb9YbJ5w lFvS70ZEaDdumYFrMYzUlcyaSr325+Iwf5AlGgjhZ4H0Yf6BHDKSQR57NPOid6aVa1GNXE5S RObX8rqamJVZ5Vmy5aFN/tIepPrcjYyj2x/L8mDa0ZgY5p7sPu6uQD8AAAAAAAA= --------------ms010901000904060906070503--
