Hi All,
I have a couple of exim (v4.95) instances running in a store and forward
manner (IP: 1.2.3.4 in the excerpt below), buffering mail from the internet,
and sending on to another exim instance (IP: 2.3.4.5 in the excerpt below).
The network link between 1.2.3.4 and 2.3.4.5 is not available all of the
time.
What I am experiencing is that If the main (IP: 2.3.4.5) server mail offline
for more than two days, e-mail is being discarded by the forwarding instance
(IP: 1.2.3.4).
The only relevant lines in the configuration (on IP: 1.2.3.4) I can see are
as follows:
ignore_bounce_errors_after = 10w
timeout_frozen_after = 10w
.
begin routers
smarthost_1:
driver = manualroute
domains = +local_domains
local_parts = ${lookup mysql{"some sql stuff.."}}
transport = remote_smtp
route_data = 2.3.4.5
begin transports
remote_smtp:
driver = smtp
message_size_limit = ${if > {$max_received_linelength}{1200} {1}{0}}
begin retry
2.3.4.5 * F,2h,15m; F,31d,1h
domain.com * F,2h,15m; F,31d,1h
* * F,2h,15m; G,16h,1h,1.5; F,4d,6h
The emails in question are being send to [email protected]
<mailto:[email protected]> from anybody on the internet. The event cases I am
trying to cover are that exim 1.2.3.4 when connected to 2.3.4.5 has the tcp
connection refused (e.g. not on net), or that host 2.3.4.5 issues a 4XX
error, or even an 5XX error, to exim hosted at 1.2.3.4 but want the mail to
be retained on the store and forward instance for up to a month, with a
retry mechanism. 2.3.4.5 is the final destination for the mail.
Imagine that 2.3.4.5 is only online / executing for a specific schedule and
period.
Any ideas as to what I have misunderstood about the retry mechanism or any
other issues someone more experienced than I can see please?
73,
James
