Hi to all!
I?m setting up dovecot 1.2.8 on my system to substitute an older IMAP server and
I?m testing all features of Dovecot.
Yesterday I was testing support for zlib, for compressed messages, to set up a
new namespace for old mails and I read that it is safe to compress only mails
that have the field ?S=XXX? in their name (XXX being the original size of
message) and to leave uncompressed the ones that don?t have S=XXX in their name.
Testing and searching I discovered that only new mail, mail that used to arrive
in mailbox via SMTP have S=XXX, mail copied from another mailbox loose S=XXX.
Later I?ve found that this not work anymore, even directly delivered mail
messages do not have S=XXX anymore. I use dovecot-lda as delivery program and
postfix as SMTP server, but I?ve not touched postfix configuration since one
month ago. What can it be? How can I have S=XXX again in my messages file name?
TIA
Andrea
