Hi, The latter is "simply" a base64 encoding: $ echo 'VG9tYXMgTWFydGnFoWl1cyA8dG9tYXNAcHVnYS52ZHUubHQ+' | base64 -d Tomas Martišius <to...@puga.vdu.lt> Note the difference between "=?UTF-8?Q?" vs. "=?UTF-8?b?" (Q vs. b). I presume the "b" is for "binary" or/and "Base64 encoded" vs. Q which would be "quoted printed" or something like that. I am not an expert on permitted ways of quoting UTF-8 in mail headers, but the base64 method does not seem entirely inconceivable for some RFC to support that (especially not considering you can encode the body with base64).
