It's just a fact of life. Different servers use different algorithms for assigning unique IDs to mail messages. 'update-status-headers' specifies if the UID, once generated, is written back into the spool, or instead must be recalculated each time. 'old-style-uid' controls use of newer, more compact UIds versus the old ones. It may be possible to have a script add 'X-UIDL:' headers to the spool containing the old server's UIDs, causing Qpopper to use them. --
