guess you mean zlib ?

in fact i did this 2 weeks ago , no errors came up with 2.1.15,
maildirs/mailboxes got work again

my problem was ,i couldnt find out why i needed to delete index* to get
2 Mailboxes work again,for more magic, no problem in the logs and
mailboxes worked in thunderbird linux but not in thunderbird windows (
clean new setups ),i speculated to some problem with massive pop3 and
imap in parallel from different ip at same time to the same mailbox
via loadbalancers crashing something, but sadly couldnt reproduce it yet
