UID Purge?

[Kevin Myers]

In the rawlog files I get a few lines of text

1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE 
IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS 
THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN 
NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH 
ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE NAMESPACE 
NOTIFY SPECIAL-USE COMPRESS=DEFLATE QUOTA] Logged in
2 OK Begin compression (0.000 + 0.000 secs).

then a lot of binary. How do I read it?

Kevin.
