Package: icu-devtools Version: 63.1-6 Severity: important It would have been nice if you had investigated the impact of dropping icu- config. The postfix build system uses the presence of icu-config to determine if libicu is present (and thus SMTPUTF8 support should be built in). See #921075.
In my opinion, postfix is not releasable in its current state. Please put icu-config back or provide a tested alternative to enable postfix to build correctly. Scott K
