Cannot Send Mail The recipient “abc@example.com” was rejected by the server

Issue:

user will received this error message from email client when try to send email.
"Cannot Send Mail The recipient “abc@example.com” was rejected by the server"

Affected Users:

Email users using ipad/iphone/androind

Reason:

Then you most probably did not set SMTP authentication when the email account was configured on that specific device. This is not only the user’s fault, Apple states in the configuration steps that these credentials are optional, well, they are not really optional, unless the SMTP server you are using is Open Relay.

Solutions:

Access your Settings icon > Mail, Contacts, Calendars > Email account > Account > “Outgoing Mail Server” | SMTP > Primary Server

Here you will have to complete the following fields:

User Name: <your full email address> (in most cases the email address is also the SMTP User Name)

Password: ***** (your email password will go here)

Authentication [usually here you select Password]

Please enable SSL

Next, in order to save these settings, tap on “Done” in the upper-right corner. Now you should be set up and ready to send some emails.
