尝试按照Arch Linux Wiki的Sieve教程 （我遵循虚拟用户邮件系统教程结束了这个教程 ）设置邮件服务器。
这应该启用spamtest和spamtestplus 。 逐字sieve_trace_debug Wiki除了sieve_trace_debug之外所要求的sieve_trace_debug并删除文档的可读性。
/etc/dovecot/conf.d/90-sieve.conf ：
plugin { sieve = file:~/sieve;active=~/.dovecot.sieve # Start Arch Linux Wiki Config <https://wiki.archlinux.org/index.php/Dovecot#Sieve> sieve_extensions = +spamtest +spamtestplus sieve_spamtest_status_type = score sieve_spamtest_status_header = \ X-Spam_score: (-?[[:digit:]]+\.[[:digit:]]).* sieve_spamtest_max_value = 5.0 sieve_before = /var/lib/dovecot/sieve/global_sieves/move_to_spam_folder.sieve # End Arch Linux Wiki Config sieve_trace_debug = yes }
这应该是路由垃圾邮件到一个垃圾邮件文件夹。
/var/lib/dovecot/sieve/global_sieves/move_to_spam_folder.sieve ：
require "spamtestplus"; require "fileinto"; require "relational"; require "comparator-i;ascii-numeric"; if spamtest :value "ge" :comparator "i;ascii-numeric" "5" { fileinto "Junk"; }
试图编译以上。
$ sudo sievec /var/lib/dovecot/sieve/global_sieves/move_to_spam_folder.sieve ：
move_to_spam_folder: line 1: error: require command: unknown Sieve capability `spamtestplus'. move_to_spam_folder: line 6: error: unknown test 'spamtest' (only reported once at first occurrence). move_to_spam_folder: error: validation failed. sievec(foo): Error: failed to compile sieve script '/var/lib/dovecot/sieve/global_sieves/move_to_spam_folder.sieve'
没有工作，因为它无法findspamtest和spamtestplus 。 所以我testing了configuration。
sudo sieve-test -t - -Tlevel=matching /etc/dovecot/conf.d/90-sieve.conf /home/foo/test.eml ：
90-sieve.conf: line 2: error: unexpected character(s) starting with '='. 90-sieve.conf: line 2: error: expected end of command ';' or the beginning of a compound block '{', but found unknown characters. 90-sieve.conf: line 2: error: unexpected character(s) starting with '~'. 90-sieve.conf: line 2: error: unexpected character(s) starting with '='. 90-sieve.conf: line 2: error: expected end of command ';' or the beginning of a compound block '{', but found unknown characters. 90-sieve.conf: line 2: error: unexpected character(s) starting with '.'. 90-sieve.conf: line 2: error: unexpected character(s) starting with '.'. 90-sieve.conf: line 5: error: unexpected character(s) starting with '='. 90-sieve.conf: line 5: error: unexpected character(s) starting with '+'. 90-sieve.conf: line 5: error: unexpected character(s) starting with '+'. 90-sieve.conf: line 7: error: unexpected character(s) starting with '='. 90-sieve.conf: line 8: error: unexpected character(s) starting with '='. 90-sieve.conf: line 8: error: unexpected character(s) starting with '\'. 90-sieve.conf: line 9: error: unexpected character(s) starting with '-'. 90-sieve.conf: line 9: error: unexpected character(s) starting with '-'. 90-sieve.conf: line 9: error: unexpected character(s) starting with '+'. 90-sieve.conf: line 9: error: unexpected character(s) starting with '.'. 90-sieve.conf: line 10: error: unexpected character(s) starting with '='. 90-sieve.conf: line 10: error: unexpected character(s) starting with '.'. 90-sieve.conf: line 12: error: unexpected character(s) starting with '='. 90-sieve.conf: line 12: error: unexpected character(s) starting with '.'. 90-sieve.conf: line 15: error: unexpected character(s) starting with '='. 90-sieve.conf: error: parse failed.
显然它甚至不能读取/etc/dovecot/conf.d/90-sieve.conf ？ 而且在等号上窒息？
看来，如果我修复这个错误，我可以启用spamtest和spamtestplus ，这将反过来[可能]修复sievec编译错误。

Dovecot根本不是来源于你筛选的configuration。 如果你使用“per-feature”configuration文件，你的/etc/dovecot/dovecot.conf文件应该包含一个像
# Most of the actual configuration gets included below. The filenames are # first sorted by their ASCII value and parsed in that order. The 00-prefixes # in filenames are intended to make it easier to understand the ordering. !include conf.d/*.conf
它在conf.d生成单独的configuration文件。
