[Dovecot] POP3: Keep a copy on server failed ...

[Dominique Feyer]

I change nothing since 1 weeks, last update was to remove the ACL
plugin.

For default_mail_env, I have:

default_mail_env = maildir:%h/:INDEX=MEMORY

For pop3_uidl_format, I read in the comment of the sample conf file:

"UW's ipop3d : %08Xv%08Xu" and a few line after "%08Xu%08Xv will be the
new default" This is not the same string and I use the second "%08Xu%
08Xv"

This is strange the default Dovecot is %08Xu%08Xv and for UW is %08Xv%
08Xu ?

Thanks
