The Identities section in MailDroid allows you to control and to create custom identities.
Let's begin by discussing 'Identities'. The first question you may have is, what is it? Imagine you have another email address (info@whatever.com) forwarded to your "main" email (really-me@domain.com) and are frustrated that your replies are appearing to be from really-me@domain.com instead of info@whatever.com, you'll want to create an identity.
How do you create the identity?
After this is done, you can now send email from this account. Since this is an identity only (just SMTP settings), you can only send and will not be able to receive email.
NOTE: When you set up your outgoing SMTP server, keep in mind, that most mail servers will only allow you to send email through their server with a "From" domain that matches their email accounts.
How do I delete an identity in MailDroid?
How do I see emails sent from an identity in MailDroid?
How do I edit information such as name, SMTP, or Signature?
Is there anything specific I need to know about identities and how they work in MailDroid?
To summarize, identities are not the same as an email account. In fact, identities in MailDroid are global, and MailDroid will automatically use those settings when you pick the identity that has it listed as an email address.
In the future, more options may be added to this feature.
