您好，张工
1.很多用户经常出现这种错误，以上是dovecot.log 的报错日志信息，以下是dovecot-sieve.log的报错

2.个别用户的邮箱账户会出现无法正常登录收取邮件的问题，日志有索引错误，需要删除个人邮箱目录下的 dovecot.* 文件即可恢复，但是问题无法根本解决，使用过程中还会出现，而且需要全部移走cur目录下的历史邮件，不然再次登录客户端Foxmail outlook会全部重新收取历史邮件，而且重新回复后个人的文件目录下先比原来缺少了两个文件（ dovecot.index.thread和dovecot.mailbox.log ），以致于还会重现相同的报错。不知道如何能够实现根本修复
