ResenderForward SMS to any mailbox — your own domain, GMX, Mail.ru, Zoho, a company server
Resender does not have a server of its own: every SMS goes out through your mailbox, from the phone, over SMTP — the protocol every mail provider speaks. Enter your address; Resender works out the rest for more than forty providers, and lets you type the server settings for the others.
Setup
- Install Resender from Google Play on the Android phone with the SIM card.
- Open Sending method and enter your email address. Resender looks the provider up — by the domain and, for your own domain, by its mail records — and fills in host, port and encryption. It then shows the provider's own steps for a password it will accept: most want an app password created in the account's security settings, some first want mail programs allowed, a few take the account password as it is.
- Paste the password and tap Save and test. Resender sends a test email to the address; when it arrives, the sending method shows Working.
- A server Resender does not know: open Server settings and enter host, port, username and password, and choose SSL or STARTTLS — the same values your mail program uses. Resender never sends without encryption.
What the messages mean
- The server rejected the login or password. Check both; you probably need an app password instead of your sign-in password.
- Password accepted, but mail app access is disabled. The provider blocks mail programs until you allow them in the mailbox's settings.
- The server offered no encrypted connection on this port. Choose SSL and port 465 under Server settings.
- The server did not respond. Check the internet connection, the host and the port.
- This provider requires browser sign-in. The provider no longer takes passwords from mail apps and Resender has no sign-in button for it yet; use another mailbox as the sending method and add this address as a recipient.
What arrives
Each SMS is one email from your own address to the recipients you chose — the sending mailbox need not be the same as the recipients. The subject starts with [SMS] and the sender in brackets, followed by the text of the message. Rules in the app decide which senders go where; the battery guides keep the phone from stopping Resender in the background.
Questions
Which mailboxes work without any typing?
Those Resender recognises from the address: Gmail, Outlook and iCloud, and also GMX, WEB.DE, T-Online, Mail.ru, Rambler, Zoho, mailbox.org, Posteo, Orange, Laposte, Free, Libero, Virgilio, Seznam, Centrum, WP, Onet, Interia, O2, QQ, 163, 126, Sina, Aliyun, Naver, Daum, Yahoo Japan, Biglobe, Nifty, UOL, Rediff, Walla, ukr.net, i.ua and more. The list grows with releases.
Does my own domain work?
Yes, when the domain's mail is hosted by a provider Resender knows — it looks the domain's mail records up and finds, say, Google Workspace or Zoho behind it — or when you enter your server's settings by hand.
What about Proton Mail?
Not possible. Proton has no mail server that apps can talk to; sending requires Proton Bridge, a program that runs only on a computer. Pick another mailbox as the sending method and add your Proton address as a recipient.
The server rejected the login or password.
Most providers want an app password, not your sign-in password: create one in the provider's security settings and paste it. Some require you first to allow mail programs to access the mailbox. Resender shows the provider's own steps when it recognises the address.
Which port and encryption do I choose for a company server?
Ask the administrator or copy the settings from your mail program: usually port 465 with SSL, or 587 with STARTTLS. If Resender says the server offered no encrypted connection on the port, switch to SSL and port 465. Resender never sends without encryption.
