Why does it say my email was "rejected by the server because it does not allow relaying" when I try to send it?

I'm able to download/get my email just fine but when I try to send an email, I get the message that my email was "rejected by the server because it does not allow relaying." What gives?

If you try to send an email from your iPhone 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.

4. Even though it says "Optional," fill out both user name and password under Outgoing Mail Server.

5. Tap "Done" in the top right to save your changes.

How to set up outgoing mail server in iOS 8


I tried the fix but when I got to Gmail SMTP Server area it is greyed out and will not let me do anything - user name etc.


Awesome! Thanks so much for posting this ❤️❤️

I was starting to lose the will, then found this post and now all sorted. BIG Thank you

I agree with this one! See mine from 11/1/17

Thanks it works for me (Y)

It happens because of more number of ssl certificate is on

Can you say more on how to turn the ssl certificate off? I would like to test this.

This advice looks promising.
I also see some online advice to try and change the port # to 25.
But when I arrive at the email account SMTP Server window the only thing I can change is turning the server on or off. All other fields are light gray (not changeable).
I find the same in both gmail and yahoo from my iphone6.
Now what?

When I get to step 4 it won’t let me go further, use ssl is very lightly highlighted in green but I can’t get it bright

This worked great!! I was baffled by this problem, and now it's gone!

Same problem as others stated here. I fixed according to instructions, then tried to send and still email not going!! What to do?

This TOTALLY WORKED INSTANTLY! Not all of these online fixes work, or they suggest you download some obscure software or APP. This was easy and simple. Thanks!

This still did not solve the f*^#^ problem

Thank you so much! Life saver:)

This problem have been driving me nuts. Thanks to your help I finally sorted it out. 10 stars to you!!!

Superstar - thanks so much - worked first time!

I have had this problem with IPhone 6s Plus and now with IPhone X. I follow instructions but can’t enter any changes because all grayed out and won’t accept. Does anyone have any other ideas. Very frustrating.

Tried all of the suggestions and more, still no joy HELP

wow!! it worked!!!

When I go to the options and host name, etc, it is all grayed out. Help?!
