Thanks all for your replies , I already installed postfix “compile,installed” and I got the below warning although I already installed icu “dependencies” postfix: warning: smtputf8_enable is true, but EAI support is not compiled in and the Unicode files are already there as well. Did anyone face this issue before ? Or is there any advice ? Thnx All the Best, Abdalmonem Tharwat Galila Deputy Manager, Dot Masr Registry, Operation Sector.
