Sep 17 08:55:01 mailserver CRON[4257]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)

这是筛子规则：

require ["variables", "fileinto", "mailbox", "vnd.dovecot.execute"];
if address :matches "from" "*" { set "from" "${1}"; }

if anyof ( header :contains "subject" "unsubscribe neighbours",
                header :contains "subject" "unsubscribe neighbors") {
  execute "smtp" "-neighbors=${from}";
  fileinto :create "Unsubscribe.Neighbors";
} elsif address :contains "from" ["mailer-daemon", "postmaster", "internet mail delivery"] {
  if header :matches "X-Failed-Recipients" "*" {
    execute "smtp" "-email=${1}";
    fileinto :create "Mail Delivery System";
  } else {
    fileinto :create "Mail Delivery System.Warning";
  }
} else {
  # The rest goes into INBOX
  # default is "implicit keep", we do it explicitly here
  keep;
}

尝试过

/etc/dovecot/conf.d/90-sieve.conf

vsz_limit = 256M，但没有成功

有人可以帮我解决吗？

Answer 1

对于任何可能偶然发现同样问题的人： 这似乎是由 Golang 1.14 及更高版本中内存分配器代码的更改引起的 - 请参阅Go问题。 我已经能够通过将 lmtp 进程的 vsz_limit 设置为 768MB 来规避它。

Answer 2

最后将

go

重写为

rust

:( 一切正常。
