I have: > the_local_p...@mydomain.name * sender@some_domain_name F,24h,1m [...] Hello, I think the FAQ-response is too short. (But I fail to quickly come up with a better one) A9807: Set up a router like this: [... router ... ] | Of course, this will also have the effect of setting a retry time for | the address. You may want to set a special retry rule for it. Note the | use of \no_verify\ to ensure that this router is not used when Exim is | verifying addresses. Afaiui the reason that retry rules need to changed is to avoid delaying longer than 24 hours. - Since every message is defered retry rules with long intervals will hit. Using the default config * * F,2h,15m; G,16h,1h,1.5; F,4d,6h messages will be delayed by not 24 but 24+6 hours. (They defered for a long time and hit the F,4d,6h-part) So you would want to modify this to have small retry intervals (15m?) for up to 25 hours. Setting a long interval for the first 24 hours would just be an optional performance optimization. Deferal is caused by the router, not the retry rule. I think reception of a second or third to-be-deferred message while the first one is still deferred does not make difference BTW. (Unless exim does not retry the oldes message first and messages queu up until the *newset* one is 24 hours old. - If it does not the whole scheme breaks and messages queue up until the *newset* one is 24 hours old.) cu Andreas -- `What a good friend you are to him, Dr. Maturin.
