How do you do.

I have tried to use SiS to deduplicate attachments in mail storage.
Unsuccesful. When goes mail with reasonable size, and SiS try to start,
I have receive error, when this mail must be delivered for group of
receivers (i.e. through aliases).

Below is error log, valuable parts of mail addresses masked by X and Y chars

msgid=<2015080614471325760993 at chinacoalchem.com> (from
zsy at chinacoalchem.com): saved mail to INBOX

This receiver has received mail. But next one does not. And to receive I
must restart _sendmail_ (not dovecot!). I must restart sendmail as many
times as there were recipients in envelope.

Why LMTP, when try to deliver mail to local user yyyy tries to look up
into a home directory of local user xxxxx? All these and similar home
directories has a 'mail' subdir, which keeps mail and rights on this
subdir is 0700.

To avoid this completely misunderstood occassion, I have temporary set
mail_attachment_min_size to 2048kb - but now I cannot receive advantage
from SiS.
