动不动就崩溃闪退

会崩溃,也一如既往的慢

No combined Inbox, Sent, etc.

Sadly there are so many things missing.

- No combined Folders for alle Email-Accounts like Apple Mail has
- No right swipe option for unread
- No option to configure swipe left option
- Very slow even with very fast 1000 Mbit/s Internet-Connection
- No icons in favicon in front of the mail
- No long press actions on icon

Attachments cannot be stored and Emails not being forwarded

Attachments cannot be downloaded and emails cannot be forwarded with the mobile app. That is the most basic use case I have. With the admin console via browser the search is not working at all. Trying to forward an important insurance email to myself since two days. The provided quality and service does not meet my expectations. I‘d not consider buying a qnap NAS anymore.

Edit - good client but no integrations

The app is simple yet powerful. It is the only QNAP app that makes sense. There are many missing features though. As a mail client: Send later, Smart Folders, customise badges, offline capabilities. As a mail server: Clamav-daemon on the attachments before download!
I happily migrated to Synology which hosts a fully fledged imap server.

收到邮件半天刷新不出来,自己登录邮箱的官方网页版本就能直接看到,猜测是它遵循的服务端定时从邮箱服务器拉取邮件,客户端刷新是从服务端拉取邮件,服务端没刷新客户端怎么刷新都没用。这很明显是一个不好的设计,客户端在刷新的时候也应该同步调用服务端去邮箱服务器拉取邮件,这样客户端刷新就不会是做无用功了。
