I asked myself what the -e Option in the Cyrus program deliver does. E.G. the -e is used in the postfix Configuration in master.cf, but I cannot find any reference to a -e option in the manpages of deliver.
Does anyone know what this option exactly does?
Heres a master.cf line from postfix. Alle other Options are clear to me except the -e
cyrus unix - n n - - pipe flags=R
user=cyrus argv=/usr/sbin/cyrdeliver -e -r ${sender} -m ${extension} ${user}
I know using lmtp is far better than cyrus deliver, I only used this as an example.
