功能请求：为摘要单独设置电子邮件账户

[Stephen]

跟进一下，此主题为重复内容。关于支持多个 SMTP 服务的需求此前已有人提出：

Multiple transactional email providers with auto-switch between them

Mandrill gives 12k free emails per month. Sendgrid gives another 12k free emails per month. … and there are more of such providers. It would be cool to sign up with a few and enter the corresponding SMTP authorization details of all of them in a config file and set a quota, i.e: Mandrill: username, password, 11900 (first 11900 emails) Sendgrid: username, password, 11900 (next 11900 emails) ProviderX: username, password (all the other emails) For a growing community, would save at least $10…

此处用例略有不同，但该问题源于摘要配置错误。Unix.com 拥有 138,062 名用户，即使对于密码重置等关键任务，每日 2000 封邮件的上限也仅能支持 1.8% 的用户进行日常交互。

编辑：将 2500 更正为 2000，以反映实际限制
