Iphone will receive but not send email messages

For the past several months, periodically my iPhone4 looses it's ability to send email (can still receive) and I get a message saying the userid, passowrd or other setting is invalid. Prior to getting this, I have not changed anything on the iPhone. Then after a day or two or three, for no apparent reason, email can be sent again. My email service is comcast.net.

Contact your email provider. The phone isn't deciding your password, etc. is invalid. Their mail server is doing that.

Iphone will receive but not send emails using ntlworld

My iphone 5 and ipad mini will both receive emails but not send emails using ntl world. The isp is ntlworld.com. Virgin, who run ntl, cannot help.

You have the wrong outgoing (SMTP) server settings. Contact your email provider for the correct settings.

My mail will receive but not send emails?

I am not able to send emails in MAIL, but receive them. I use a gmail email account in MAIL. I've never had a problem until a couple hours ago. Anyone know of troubleshooting info regarding this please? Thanks.

One thing you might want to do is search on google to see if they are reporting any issues with mail client usage.
Also, another option would be to reboot your Mac. Sometimes all you need to do to fix an odd problem with a computer is to reboot.

Iphone4 will receive but not send email. How do I check settings?

I am on verizon using WiFi. When I try to send a message it goes to my outbox and I get a message saying "The recipient "email address" was rejected by the server. The email addess in the message is what ever email I am trying to send to.

the settings are in General>Mail then pick whatever account yours is. the settings you want are probably in there.

Ipad will receive but not send emails

I had to change my email (yahoo) password because my email account was hacked into. Although I have changed the pasword on my ipad and can receive emails, I cannot send emails. Please help.

Check the setting this way - follow this path.
Settings>Mail, Contacts, Calendars>Your email account>Account>Outgoing mail server - tap the server name next to SMTP and check in the primary server and make sure your username and password are entered and correct - even if it says that the password is optional.

Email will receive but not send after installing os7 on iPhone 4S

Email will receive but not send after installing os7 on iPhone 4S. Checked all settings against iPad and second 4s phone and they appear identical. Other devices work fine.

Thanks Spaidr,
That was part of it. I did an end-around by setting up an alternate outgoing (send) server which was the same as the primary, identical settings, name, password. I deselected the primary and used only the secondary. Reboot as you suggested and Voila! Something must have been corrupted in the primary.
Thanks and hope this helps others.

My o2 email will receive, but not send on my ipad

My o2 email will receive, but not send. I've got other email accounts on the ipad & they all work OK. The o2 mail account used to work properly, but I needed to remove the account & since I've put it back on, it won't work on my ipad. Works ok on android mobile phone. I've checked the settings & spoken to o2, but they couldn't solve! It may be since I've joined the cloud? Any advice, gratefully received. Thanks.

Recheck the settings once again. There is something wrong. And it seems to happen to O2 people with some regularity. Google o2 mail settings and you will get a page with the details. Pay close attention to the port setting, you may need to change it on the pad, and that may be the problem.

Additional email address will receive but not send

My .mac email address works fine, sending and rerceiving in "Mail" I have another email address with virgin.net. which will receive but not send. I get a pop-up window saying "cannot send using smpt mac.com" (this is the server selected for my .mac address account) I have tried selecting the virgin smpt server but that doesn't work either. What should I do?
Thanks for all suggestions

Most, if not all ISPs block the use of SMTP servers that are outside of their network (or not provided by the ISP) on Port 25. Some ISPs allow the use of an authenticated SMTP server only (such as the .Mac SMTP server) that is outside of the network on Port 25 but some block its use regardless.
Sounds like BT Broadband allows the use of an authenticated SMTP server that is outside of their network on Port 25 and the virgin.net SMTP server must not be authenticated.
Are you accessing an email account and SMTP server provided by BT Broadband with the Mail.app?
Something to try.
Go to Mail > Preferences > Accounts and under the Account Information tab for the virgin.net account preferences at the SMTP server selection, select the Server Settings button below.
Enter 587 in place of 25 in the Server Port field and when finished, select OK to save the changed setting.
If this doesn't resolve the problem and you are accessing an email account and SMTP server provided by BT Broadband in Mail, select/use BT Broadband's SMTP server to send mail with your virgin.net account which is invisible to all recipients.
These SMTP server restrictions are in place as part of an overall effort to prevent spam emanating from the ISP's domain.

Trying to set up mail.. will receive but not send

Trying to set up mail.... will receive but not send. Already called internet provider. They said ask Apple.

Hi ...
Mac Pro, Mac OS X (10.7.2), Lion.
From the Lion Help viewer ...
If you can’t send messages
If the Send button is dimmed or you see an alert that your message can’t be sent using the outgoing mail server, you might not be able to send messages. Here are some things you can try:
Make sure the outgoing mail server is specified correctly, as directed by your email service provider.Verify your outgoing mail server
If you try to send a message and a dialog appears saying you need permission, an administrator has limited the email addresses you can correspond with. Click the Ask Permission button.Request permission to send messages
Choose Window > Connection Doctor, and follow any instructions displayed in the Details column. Check whether there is a problem with your outgoing mail server or a firewall, if applicable, or if there was a login failure. If the Connection Doctor indicates a firewall problem:Verify there is no firewall software blocking email traffic on port 25, 465, or 587.Check whether you’re affected by another firewall. This could be either software installed separately from Mac OS X or built into an Internet sharing router, or software administered by your Internet service provider. Contact the appropriate person to find out whether a firewall exists.
You may be able to send messages from only a certain location. For example, if you send messages from school, you may not be allowed to send messages using the school’s outgoing mail server when you’re at home. Or, the email service provider may allow you to send messages but with stricter settings (such as requiring a name and password). Get the information you need from your provider and then change the outgoing mail server settings in Mail preferences.

I can receive but not send emails with my skynet account - what am I doing wrong ?

I can receive but not send emails with my skynet account - what am I doing wrong ?
I have no problems with my Yahoo account but I can not send emails with my skynet account.
Actually in iPhone :
Outgoing Mail Server > SMTP "relay.skynet.be"
Primary server > Not Configured > Off
Thank you ...

When you set them up, did you set up both the incoming and outgoing email servers separately, and did you enter the correct SMTP server name, and enter your userid and password even though it says "optional"?
Something else to try, if you haven't, is delete the accounts, connect the iPhone to iTunes, on the Info tab check the box to sync mail server settings, then sync. This should duplicate the settings from your computer to your iPhone.

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.

Why can I receive but not send emails

Why can I receive but not send emails on my i pad?

Perhaps the outgoing mail server settings are incorrect or incomplete.
Settings>Mail, Contacts, Calendars>Your email account>Account>Outgoing mail server - tap the server name next to SMTP and check in the primary server and make sure your username and password are entered and correct - even if it says that the password is optional.

TS3899 my Iphone allows me to receive but not send emails. How do I get it to send emails?

My iphone will not send email messages, only receive them. It is linked with my Mac. Wondering if the issue has something to do with Itunes being registered with my husband's account? Maybe I'm grasping at straws...

Thank you! I am so tech deficient that I just don't know what to do when I have a problem and this fixed it right away and was so easy for me to follow your directions. Really appreciate your help!!
