**(62) Can CRAM-MD5 authentication be supported?**
**(62) Which authentication methods are supported?**
Unfortunately, [JavaMail for Android](https://javaee.github.io/javamail/Android) does not support SASL authentication, so CRAM-MD5 authentication cannot be supported.
The following authentication methods are supported and used in this order:
* LOGIN
* PLAIN
* DIGEST-MD5
* NTLM
* XOAUTH2 (used when an account was selected)
SASL authentication methods, like CRAM-MD5, are not supported
because [JavaMail for Android](https://javaee.github.io/javamail/Android) does not support SASL authentication.

**(63) How are images resized for displaying on screens?**
After adding an inline image or an image attachment you might be asked if you want to reduce the image size for displaying on a screens.
If you answer "yes", the image will be resized to a maximum width and height of about 1920 pixels and saved with a compression ratio of 90 out of 100.
Images are scaled down using whole number factors to reduce memory usage and to retain image quality.
