I can receive e-mails, but can't send them from external account

I have my school e-mail account attached to my iPhone. I can receive e-mails without a problem, but whenever I try to send e-mail to someone outside the .edu server, I receive the error message: "The server rejected one of the recipient's addresses. The message has been placed in your outbox." How can I fix this problem? Thank you for your help!

This indicates the account's SMTP server is not authenticated.
Most, if not all internet service providers block the use of SMTP servers that are outside of the ISP's network or not provided by the ISP being used for your internet connection at the time unless the SMTP server is authenticated. When connected to a cell phone carrier's cellular network for internet access is no exception. Does this occur when connected to the school's wi-fi network in addition when connected to AT&T's cellular network?

HT1911 i cannot find my account password, i tried to receiving e-mail but there is no answer from itunes store.

i cannot find my account password, i tried to receiving e-mail but there is no answer from itunes store.
my account's e-mail has a word '+' for using multiple account to accessing another country's store.
for example. 1. [email protected] 2. [email protected] 3. [email protected]
like this.
so, i forgot it. but there is no way to find my password.
and i couldn't find any answer for this situation.
i think there is a problem that my account has + word. so maybe apple's automatic answering system does not work with that.
please help me. thank you.

TS3899 I can't SEND email from Telus account in Alberta, Canada? Does anyone know how to set up the Outgoing server? Help! And thanks!

Can't SEND email from Telus account in Alberta, Canada, unless I go to web mail. Does anyone know how to set up the Outgoing server? Incoming is fine. Outgoing used to work. We changed it when we went to another location, and can't get it back. Telus support can't fix it. Neither smtp.telus.net NOR mail.telus.net works for Outgoing server to send mail. Please help! Thanks.

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.

Receiving e mail but unable to send

I am receiving e mails but unable to send

Who is your email provider?
Have you contacted them to make sure the outgoing mail settings are correct?

Can receive e-mails but unable to send e-mails (BES)

Hi everybody,
Whenever I send an e-mail I get this X sign and a message saying "Service Blocked". However, I can receive e-mails and it says Received As Desktop (Secure). I contacted Saudi Telecom and they assured me that my account is BES and they even showed me that in the screen.
I'm kind of lost, I tried all solutions but nothing worked for me. I have the 9000.
Many thanks for your support,

Hello naserals
I can tell you with 100% certainty that you do not have to correct
plan for BES email. Contact your service provider and tell them you need to
have BES services provisioned on your account. If they say the
provisioning is correct tell them you want to talk to a supervisor because it
is not correct.

Able to receive e-mail but unable to send.

Hi,
I've had my Macbook Pro since January and have my e-mail accounts set up through mail. About a week ago my cox accounts stopped sending email. The error states that the server does not recognize the smpt account. I called Cox and everything is working on their end. I can send and receive from the webmail site and my smtp is set up properly.
I tried deleting the mailbox to re-set it, but it doesn't delete. It asks me if I'm sure I want to delete; I click yes; it's still there.
Any help will be greatly appreciated!

You need to make sure your Outgoing mail Server is correct in Mail>Accounts>Accounts Setup. In any case SL Mail and AddressBook forum is here:

Can't send email from any account in Mail app

Suddenly, a couple of days ago, Mail started refusing to send mail in my .Mac account. I changed nothing in terms of settings and the way I do stuff. Receiving has been unaffected.
I'm at a loss to think what it could be... any ideas?
Thanks.

Sure your ISP provides some POP and/or IMAP accounts with access to an SMTP server as part of the service. Have you tried sending with that?
In an attempt to fight spam, many ISPs restrict the ability to send using an outgoing (SMTP) server not owned by them, usually by blocking port 25 for all traffic outside their own network, which means you cannot send with an SMTP server not owned by them if configured to use that port number.
Something that often works is changing the outgoing server port to 587 (or whatever alternate port number the outgoing server listens to) instead of 25 and using some form of authentication in Preferences > Accounts > Account Information > Outgoing Mail Server > Server Settings, but two conditions must be satisfied for this change to work: (1) the ISP must not block that port as well AND (2) the outgoing server in question must listen to that port and accept a form of authentication not based on the IP address you’re connecting from.
Independent mail service providers not tied to a particular ISP, such as .Mac and Gmail, do allow authenticated SMTP access on port 587, which is the reason changing the outgoing server port number solves the problem for them if the ISP doesn’t block that port as well:

Can't send email from iCloud accounts on Mac

A few hours ago I couldn't login and receive email to my icloud accounts this appears to have been fixed but I still cant send email. I've checked all passwords in preferences.
I can login to icloud via the browser and send email Ok.
I can send email from my iCloud accounts on my iPhone.
But can't send mail using Sparrow or Mac Mail on the desktop.
This all seems to have happened since I installed the latest security update.

Using smtp.mail.me.com - also tried smtp.me.com
SSL yes
port 587
SMTP Authentification Yes
Security SLS/TLS - also tried STARTTLS
User full **@me.com email address - also tried user name without @me.com
I have spoken to apple support this afternoon and we tried the variations shown above.
Support told me to wait for a day and try again!
After the iCloud authentication problem last night I changed all my passwords I wonder if there is an SMTP problem at me.com perhaps not reading the updated passwords?
I'll try and use the old passwords later.

Can not send email from corporate account when out of office

I have a 3G+wifi ipad, my sending via corp email works when I'm in the office (connected via wifi) but doesn't send when I'm on 3G and other wifi network (my home wifi). When I send from the other locations I can send from yahoo account only. I have tried to change the server port a couple of times but still no luck. Anyone has any idea how solve this problem?

I am still having some of the problems the guy who can't get corporate emails has.
You have already read my thread. Yesterday was a good day, I got every single email I received on my iPhone and main Mac computer on my iPad.
I powered the Pad down last night, turned it on this morning and only got 2 of the 4 I was sent during the night, 2 of them being from my US HO but yesterday I got emails from my US HO on my iPad early in the evening.
I have learnt that ntl world emails cannot be received with 'Push' so that cancels out that being anything to do with it.
There is only one difference in my settings so don't know if this is making any difference:-
On my iPad the smtp authentication is MD5 Challenge-Response.
On my iPhone the authentication is Password, I have tried changing it but it won't let me. Can't think that this is the problem as this is on the Outgoing Server of which I have no problems.
Another odd thing is that when I got my iPhone last year I synched the account settings through iTunes. I did this 3 weeks ago when I got my iPad. I then unselected synching the accounts in iTunes when the Pad was connected as I wanted to set them up manually. Now I cannot access this part of iTunes for the phone or pad, it's ticked but greyed out and doesn't show any of my 4 accounts.
One of the main reasons I bought a Pad is to do emails on it as I find the iPhone a little small to use all day. I am gutted that the Pad is not getting all mails and can't trust it.
Could it be that when I power down it affects the settings as that's the only thing different I did yesterday. I will keep the pad on all day and night but this should not be the problem can it? Don;t want to waste power having it on all evening.

"Sender Name is Invalid" (can't send email from POP account) iPhone 2.1

I updated from V2.0.2 to V2.1 today. I also swapped out my original iPhone EDGE for a new iPhone EDGE due to unrelated problems with the speaker.
Upon testing things after restoring from backup to the new phone I discovered that I could no longer SEND email from my POP account. I could receive email just fine on that account. Sending and receiving email on my MobilMe account also worked, as did sending and receiving email via the POP account while on the Mac computer I use to sync with this iPhone.
After digging into this with AppleCare we discovered that somehow the Port Address for the Outgoing Mail Server for that POP account had been changed from 25 to 587 on the iPhone.
Changing it back to 25 fixed my problem.
We don't know whether the problem was due to the 2.1 upgrade or due to something in the restore process after swapping the phones.
If you get the error message "Sender Name is Invalid" while trying to send email from a POP account on your iPhone, go to Settings > Mail, Contacts, Calendars and select the line for your POP account.
Now scroll down to the Outgoing Mail Server entry which should show "SMTP" and the name of the outgoing mail server for that POP account. Select that line. This will display a list of servers with your POP account server showing at the top as the Primary Server. Select that line.
In the panel that displays, check the Server Port. If it is something odd like 587, that may be your problem. Select the line and you can edit it to something more normal like 25. Touch the "SMTP" button at the top left of the number entry screen to accept that new value.
We discovered that after correcting that value on the iPhone it STAYS corrected even after doing a new Sync with iTunes, or after MobileMe syncs.
--Bob

Sorry you had problems Bob.
Depending on the mail service you are using, Port 25 or Port 587 are usually acceptable for outgoing
SMTP mail. Many cafes will block the customary port 25 to prevent spammers from using their
wireless access.
There is a superb tutorial posted here:
http://www.webmail.us/docs/support/Macintosh-OSX-Mail.pdf
Also be sure for each mail account to turn ON the secondary AT&T server shown at the bottom
of the SMTP server list for each account -- it will make your transition from wireless to Edge
to 3G networks much more reliable.
Thanks for sharing what you've learned. Hope this helps.

Can't send messages from my accounts

Hi:
In the last 3 weeks I'm increasingly having trouble sending emails from all of my accounts. I get a "can send using server . . . " message. When I checked with the guy with my server he said everything is fine at their end and it's probably corrupt accounts.
Does anyone have any experience with this?
Also if I delete my accounts and recreate them will I lose all my emails?
If I delete one account only will I still keep the emails from the other 2 accounts.
Thanks,
Rex

Hi Rex.
Doesn’t the error message provide any additional information? Are this mail account and the associated outgoing (SMTP) server provided by your ISP or by someone else? More info, please.
