Questions and answers.
What works with which provider, where your mail lives, and what to expect when you install.
Accounts and mail
Which mail providers work?
Any provider that offers IMAP over SSL/TLS (port 993) and SMTP over SSL/TLS (465) or STARTTLS (587) with a password: most hosting mailboxes and many providers. Gmail and Outlook.com need OAuth2 sign-in, which is on the roadmap.
Can Telex send mail?
Yes. Mail goes out over SMTP, waits in the Outbox if the connection fails, and is marked Sent only once your server accepts it. A copy goes to the Sent folder on your server.
Does it work with Gmail or Outlook.com?
Not yet. Both require OAuth2 sign-in instead of a password, and that is on the roadmap.
Do changes I make reach the server?
Yes. Reading, flagging, moving and deleting happen locally at once and then on the server. If you are offline, they wait in a queue and go out at the next sync.
Can it read HTML newsletters?
Yes. HTML mail is shown in a sandbox where no script can run. Remote images stay blocked until you load them for that message, or for everything from a sender you trust (never automatically in Spam). H switches to plain text.
Privacy and data
Does Telex send anything about me anywhere?
No. There is no account, no telemetry and no Telex server. The app talks to your mail servers, and to the servers that host a message’s images only when you choose to load them.
Where is my mail kept?
In one file on your disk: %APPDATA%\app.telexmail.desktop\telex.db. Passwords are stored separately, in Windows Credential Manager.
Can I search without an internet connection?
Yes. Every downloaded message is stored in full and indexed on your PC, so the quick filter and full-text search work offline.
Installing
Which Windows versions are supported?
Windows 10 and 11, 64-bit. Telex uses WebView2, which Windows 11 already has; on Windows 10 the installer fetches it if it is missing.
Why does Windows warn me when I run the installer?
The installer isn’t code-signed yet, so SmartScreen doesn’t know it. Choose More info, then Run anyway. Signing is on the roadmap.
Is there a Mac or Linux version?
No. Telex is made for Windows first.
Is it like The Bat!?
That is the inspiration: a fast, dense, keyboard-driven client with serious filters. Telex is a new app written from scratch, and not affiliated with Ritlabs.
