当我建立邮件服务器时，我还有另一个问题，我无法在谷歌上找到，所以我希望在这里得到答案。
更新是我使用 cyrus 创建了一个带有 postfix 并通过 sasl 进行身份验证的邮件服务器，现在我正在其中连接一个 imap 服务器，因此在此过程中我使用 dovecot。
到目前为止，我发现我的 smtp 设置很好并且按我想要的方式工作，但是 dovecot 出现了一些错误。
我的配置如下

我已经允许数据库 993、995、143、80、443、25、587、465、110 中的每个所需端口......
我的表格结构如下网站
我已按照本文进行设置

答案1
我想我又犯了你的错误...哈哈
我很确定你已经搞乱了表格配置，关于如何查找表格，仔细研究你的问题，并查看你给出的网站解决方案，我发现你可能混合了两个网站的配置，两个网站都有相同的解决方案，但问题是你可能已经定义了 dovecot 的查找机制，以在表格中泄漏密码机制为 cram sha5，但到目前为止，我猜你已经将密码以纯文本形式放在表格中，因此只需更改 dovecot /etc/dovecot/dovecot-sql-conf.ext 中的密码查找机制（你的 dovecot sql 查找查询），并将表格查看机制从 sha 更改为纯文本...我想它会完成工作
答案2
我已阅读完您的帖子，没有看到任何问题。:-)
如果我理解正确的话，您有一个 SMTP 服务器 (postfix) 正在运行，并且正在使用 Cyrus SASL 进行身份验证。虽然日志似乎表明并非如此，但我会假设这是有效的。
您现在正在向此设置添加 IMAP 服务器 (dovecot)。由于 dovecot 也有自己的 SASL 实现，因此了解这两个 SASL 实现的存在非常重要。
从您的邮件日志中，我看到了 postfix 和 dovecot 的警告/错误。我想知道您的问题是关于 postfix 还是 dovecot。或者它是否与防火墙有关（在数据库中打开端口？）。
你能具体说明一下你的问题吗？
