I have this in my configuration:
protocol pop3 {
pop3_enable_last = no
pop3_uidl_format = %08Xu%08Xv
pop3_client_workarounds = outlook-no-nuls, oe-ns-eoh
}
If I change the pop3_uidl_format I need to remove all the index file on
my server ? I read on the doc that this change cann't be done on a
production server ?
I have more than 10'000 accounts on this cluster so I can't have a big
downtime.
Thanks
