使用imap方式收取邮件的用户,当他的邮箱有很多邮件(比如邮箱目录已经有5G那么大)的时候,他使用imap协议收邮件会很慢,用Webmail也很慢(因为webmail也通过imap协议)。比如,登录webmail,输入密码后要等好几分钟甚至一直进不去。有什么办法优化吗?

对比过邮箱较少邮件的帐号么?贴一下 "dovecot -n" 命令的输出看看。

对比过,最后没办法,大邮箱邮件备份后清空了,这样访问就快了

有好多用户邮件是几个G,都是有时特别慢
慢的时候用imap登录邮件少的用户是否可以,是否快 我还没试
有办法查到问题原因,并优化吗?

技术上来说,几个G的 IMAP 邮箱不算很大,Dovecot 对邮件都有做索引,因此应该不会很慢才对。
