All, I've recently implemented the address_verify_map to mitigate some verification problems we were having with a cloud provider. I had to remove one entry in this cache. After using postmap -s to export the contents to file, remove the offending entry, and run postmap again to recreate the file, I lost approximately 20,000 entries in the cache.
The original contents (before my change), had variations of different email addresses. Some examples: domainu...@domain.com<mailto:domainu...@domain.com> domainu...@domain.com<mailto:domainu...@domain.com> domainu...@domain.com<mailto:domainu...@domain.com> When running postmap to recreate the file, all of these "duplicates" were removed. Is this normal behavior? Is postfix case-sensitive with regards to recipient verification on inbound mail? Thank you.
