W is the size of the file with CR/LF for newlines. It's the same size
courier stores in the POP3 uildlist file.
I wrote an updated version of the courier-dovecot migration script
that attempts to convert in both directions (using the V3 dovecot-
uidlist format) a while back.
It's freely licensed if you want to give it a try.

Hi Timo
I aplogise if this is documented somewhere (couldn't find it), but
could you tell me what the "W<int>" field represents in a v3 dovecot-uidlist file? That is, when Dovecot v1.1.2 converts a v1 dovecot-uidlist
file, I see the following (taking the first few lines):V1 (generated by the courier-dovecot-migrate.pl script): 1 1208331473 30 2 1208332540.H167727P3133.mesg-dev2.mweb.co.za,S=343 3 1208332756.H543324P3161.mesg-dev2.mweb.co.za,S=340 4 1208332857.H236884P3191.mesg-dev2.mweb.co.za,S=339 5 1224664518.H150402P10074.mesg-dev2.mweb.co.za,S=342 6 1224664556.H128444P10080.mesg-dev2.mweb.co.za,S=339 7 1224666352.H992318P10361.mesg-dev2.mweb.co.za,S=339
V3 conversion: 3 V1208331473 N31 2 W353 :1208332540.H167727P3133.mesg-dev2.mweb.co.za,S=343:2,S 3 W350 :1208332756.H543324P3161.mesg-dev2.mweb.co.za,S=340:2, 4 W349 :1208332857.H236884P3191.mesg-dev2.mweb.co.za,S=339:2,S 5 W352 :1224664518.H150402P10074.mesg-dev2.mweb.co.za,S=342:2,S 6 W349 :1224664556.H128444P10080.mesg-dev2.mweb.co.za,S=339:2,S 7 W349 :1224666352.H992318P10361.mesg-dev2.mweb.co.za,S=339:2,
I notice that the W<int>'s are not unique (e.g. W349).
Thanking-you...

HI All,
We have the latest Dovecot 1.1.6 running and I need to migrate some POP3 users over from Courier to Dovecot and would need to convert the courierpop3dsizelist to maintain the UIDs. I just need to confirm that the script (http://www.dovecot.org/tools/courier-dovecot-migrate.pl) only works for Dovecot v1.0 and not for v1.1? As the dovecout-uidlist file that is created (by the script) is not
inthe same format as dovecot-uidlist file that is created by the 1.1.6 server.
Dovecot v1.1 can read v1.0 uidlists just fine, so the script still works. But it's possible that the script doesn't convert all POP3
UIDLs because it wasn't possible with v1.0 (it'll report how many it
couldn't convert). Dovecot v1.1 supports storing any kind of POP3 UIDLs in the uidlist file, which would make it possible to create a migration
script that preserved all the UIDLs correctly. If you or anyone else wants to try, the v1.1 format uidlist with POP3 UIDLs would look like:3 V<uid-validity> N<next-uid> <uid> P<pop3 uidl> :<filename>
Where the first line is a header. So for example with 3 different
kinds of Courier UIDLs:3 V1196932607 N125574 1234 P1234 :1225386267.M230815P21206.host 1235 P1196932607-1235 :1225386268.M230815P21206.host 1236 P1225386269.M230815P21206.host :1225386269.M230815P21206.host
