POP3 and webmail. ..
If you were thinking about just generating dovecot-uidlist and the main dovecot.index file, don't bother. Their creation is practically free.
It's not for a mailbox which has 30k+ messages and inbox around 600MB in size. Takes a while to build the index, I have tested this already. First login and index creation takes around 4-6 minutes, then next one just few seconds.
I guess you mean logging in with POP3? There the slowdown comes from getting all messages' virtual sizes. So your preindexer could probably do this by running pop3 for all users. If you use only a single UID for users, you could do something like:
for user in cat users; do
export MAIL=maildir:/home/$user/Maildir
echo "quit" | /usr/local/libexec/dovecot/pop3
done
