Hi,
As part of a backup script for cyrus-imapd, I'd like to temporarily stop
postfix delivering mails to cyrus-imapd and to just queue them. If it is
at all possible I'd like to do it without restarting any services (I
know I can just stop cyrus-imapd).
Reading what I can, there is a parameter, defer_transports, which I have
been trying to use with "postconf -o defer_transports=????" without
success. I have tried deferring smtp, lmtp and mailpostfilter, but it
does not stop mail delivery.
Syntax:
postconf defer_transports=xxx
No -o needed.

Thanks. In this case what should I use for xxx to defer delivery?
