Okay, for the records. We have recently done a short test with Postfix 1.11 -> lmtp -> Cyrus 2.0.16 and get a speed from 8 .. 40 msgs /sec (1k each) on a single IDE harddisk with 2x 266 PII and 512 MB RAM. If you get a fast SCSI-Array you can beat this rate by far. Regards -- Andreas Hödle Kühn & Weyh Software GmbH WWW.KWSOFT.DE
