Cannot send mail "The Recipient ____ was rejected by the server."

I have a roadrunner account and I am geting the same error. All my pop and imap settings went haywire after the EDGE downtime earlier. I was able to get my imap going but no luck in the pop.

Try also: In the outgoing mail, you might need to select authorization for this to work.

Go to your email settings, check for the outgoing server, select advanced options, and select the authorization settings for your server.

You might also need to check with verizon.com - sometimes servers block e-mail from phones (they have a separate ISP address) and they will need to manually unblock your ISP number (they will walk you through the steps if that is necessery). But try the authorization for outgoing mail thing first.

-mIkE,

This article has more information:
http://docs.info.apple.com/article.html?artnum=305634

As for an email provider allowing customers to relay outside of their network, many email providers, set up an authenticating SMTP server on different port. The article above includes information on specifying the port to use.

For example, .Mac accounts can use port 587 as discussed in this article:
http://docs.info.apple.com/article.html?artnum=75124

You may want to check with your email provider if they offer an authenticating smtp server for people who are traveling or using mobile devices. Many do so without any additional cost, some may charge for access to that service.

Hope this helps,

I just got my new iPhone all synced up and love it,
but I cannot send mail.

No matter which address I send to or from I get a
message saying "The Recipient whoever@whatever.com
was rejected by the server."

It took me a while, but I finally figured out that this is a bogus error; the actual error is that the server refused your send request or your ISP blocked the SMTP request. It has nothing to do with the Recipient.

See the suggestions above on how to fix it. One thing I found is that when you change settings for an email account sometimes they are not recognized. First, after making the change you must back out of the mail settings to the main settings screen. Then I have found that if I restart the iPhone after making a settings change (hold the top button and menu button for a few seconds, shut done, then press the top button to turn the phone back on) but before trying to retrieve mail this is less likely to happen.

I had similar experience. No sending on EDGE network, sent immediately when switching over to WiFi. I use a Road Runner account on my Mac, and the outgoing setttings were automatically picked up from there apparently when I sync'd the iPhone.

Thanks to a link in this thread to ATT's Web site "http://www.wireless.att.com/support/knowledgeBase.do?content=KB72769.html"
I finally got sending to work, at least while on the EDGE network. This was accomplished per ATT's site by doing:

New and Existing AT&T wireless services customers use "cwmx.com" (Standard POP/IMAP compatible. No SSL and Port 25.)

What is weird, is this seems to be a fixed issue ATT has, so why was this not preloaded on the phone to begin with.

Also, I suspect now that when I drop in to a WiFi zone, that I will again not be able to send email as the outgoing server name is incorrect.... we'll see.

later all.... joe

OK guys, I fixed the problem. ( I think)

I looked in my "real" Mail app's (on the computer)
account settings and figured out the problem.

In MAIL:
for smtp,in SERVER SETTINGS I type in

outgoing mail server: mail.mydomain.com
I type in username: my email@mydomain.com
and password: mypassword

what Mail then does is add to the outgoing mail
server SMTP drop down menu the choice
"mail.mydomain.com: email@mydomain.com "

In the iPhone, the SMTP settings just list
mail.mydomain.com as the outgoing server.

I changed that to
mail.mydomain.com: email@mydomain.com

and now I can send at work using wi-fi, so I think it
is fixed.

Wow thanks mike this fixed my same problem.. PLease bump this page

Note that some cable ISPs do not use authentication to send mail out on their SMTP servers, they track the IPs that authenticate for incoming mail and allow SMTP traffice from those IPs.

Also, your cable modem's DNS name usually has the name of the ISP in there somewhere, and when they see an SMTP request from that DNS name they know enough to allow it.

For a while there, I could not send mail from my Comcast account unless I was at home on my Comcast modem - it's possible there is some tom-foolery going on with Road Runner is the same vein.

A good workaround would be to get a free email account like Gmail or Yahoo and use the credentials for that account as your outgoing mail server, effectively bypassing your ISPs SMTP server. So your account settings would look like:

yourmail@yourispemail.com
incoming mail server: pop.yourispemail.com
username: yourmail
password: your password
outgoing mail server: smtp.gmail.com
username: yourgmail@gmail.com
password: your gmail password

Just a followup to my previous reply.

I did try last night sending an email from my local WiFi connection, and as expected the "fix" for sending email while on ATT's EDGE network, was not accepted when on my local Time Warner Road Runner connection via WiFi.

For me, this isn't that big a deal, as I'm only likely to send an email from my iPhone when I'm not near a computer. However, it does seem a little odd is why the Locations concept was not carried over to the phone since this is already in OSX, they almost had to change it on purpose. Being that this seems to be a given for use on the ATT network, its even odder.

Surely there's a better way, but if it is, it isn't obvious.
