Mails with verification code from Ikea are deferred. In log:
H=mail18.ikea.com [192.71.69.88] I=[xxx.xxx.xxx.xxx]:25 sender verify defer for <no.reply@ikea.com>: host lookup did not complete
nslookup -type=MX ikea.com Server: 127.0.0.1 Address: 127.0.0.1#53 Non-authoritative answer: ikea.com mail exchanger = 0 ikea-com.i-v1.mx.microsoft.
To test issue run command:
exim -bt -d-resolver no.reply@ikea.com
First run of command returns strange TRY_AGAIN for MS MX:
R: dnslookup for no.reply@ikea.com calling dnslookup router dnslookup router called for no.reply@ikea.com domain = ikea.com ikea.com in "*"? yes (matched "*") DNS lookup of ikea.com (MX) succeeded DNS lookup of ikea-com.i-v1.mx.microsoft (A) gave TRY_AGAIN ikea-com.i-v1.mx.microsoft in dns_again_means_nonexist? no (option unset) returning DNS_AGAIN writing neg-cache entry for ikea-com.i-v1.mx.microsoft-A-800041, ttl -1 fully qualified name = ikea.com host_find_bydns yield = HOST_FIND_AGAIN (1); returned hosts: ikea-com.i-v1.mx.microsoft <null> MX=0 * dnslookup router: defer for no.reply@ikea.com message: host lookup did not complete no.reply@ikea.com cannot be resolved at this time: host lookup did not complete search_tidyup called >>>>>>>>>>>>>>>> Exim pid=2599490 (fresh-exec) terminating with rc=1 >>>>>>>>>>>>>>>>
Second run works correctly:
