If your friends and family are saying you're sending them text messages from your email them something is wrong with your settings. This tends to occur when you purchase a new phone, or sometimes when you update your device. Luckily there is an easy fix. Here's how to stop sending messages from your Apple ID/email and send them from your phone number:
Email and Messaging
For those not familiar with it, Telegram is a popular messaging app with privacy features such as end-to-end encryption on "secret chats" that can only be accessed on the devices they originated on. Because of this it has gained notoriety as a tool used by terrorists and has even been banned in Russia and Iran where it has been deemed a tool of social dissidents. Nevertheless, Telegram is a well-done app for simple, fast and secure messaging.
Sending group text messages or iMessages is a convenient way to have a conversation with multiple contacts using iOS. Going back to a message thread will resume this conversation with the same people. So is it possible to add or remove one contact from the list of people already on the group text?
You may have noticed that some of your iPhone text messages have either a blue or green background.
A blue background means that the message exchange is happening via iMessage with another iOS device (an iPhone, iPad, iPod Touch, Mac, etc). These messages are sent through your cellular provider's data network or via WiFi (no cell service needed), and text message rates don't apply
If you try to send an email from your iPhone on iOS 8, or an earlier iOS for that matter, and get an error message that says "A copy has been placed in your outbox. The recipient was rejected by the server because it does not allow relaying," chances are you need to check your outgoing mail server settings. Here's how:
1. Go to Settings -> Mail, Contacts, Calendar and tap on your email account.
2. Tap on "Account," then go down to the "Outgoing Mail Server" section and tap on "SMTP."
3. Tap on your Primary Server.
