Can't send..sender email invalid

My pop email account has worked perfectly until this morning. I am currently traveling in my car (not the driver) and I was trying to reply to an email. When I tapped send, after a while I got the message unable to send...sender email invalid. Also all of my read emails have disappeared. Where they were is a message that says retrieve more messages - 9 read. I used my .mac account to send a message to the pop account and it comes in fine.
Any ideas as to what may be going on? I really need that account on this trip.

Hey,
Verify the outgoing mail server settings, goto Settings> Mail> Tap the account> Tap the outgoing mail server.
If it appears correct and still does not work, try deleting the account and then add it again.

"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.

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.

Is this your machine or the company's? Machines that came with Snow Leopard or earlier installed come with system and software install disks that can be used to reisntall the iApps that came with the machine orignally.
If this is your machine and it came with Snow Leopard or earlier installed the disk will look slimialr to one of these:
If it is the company's machine see if they have the disks.
Do a custom install and then use Software Update to update iPhoto to the highest version that is available.

When sending an email I used to be able to add a distribution list from my contacts, I now have to add each email address individually, does anyone know how I can add the whole list?

When sending an email I used to be able to click on a distribution list in my contacts and it would add all the email addresses, I now have to add each email address individually and this takes a lot of time. Could someone tell me how I can add a distibution list/group to my emails?

Barney,
I have four groups.
I just typed the name of one of those groups in the To field on the iPhone's email, and received:
Invalid Address
"<group name>" does not appear to be a valid email address. Do you want to send it anyway?
I clicked continue and it remains in my outbox.
Help is appreciated.
Thanks,
Michael

I can receive emails, but I cannot send emails. This just started happening. I have an iPhone and I can send emails from my phone fine. It's just not working on my Macbook. Every time I try to send an email it goes straight to my outbox. Can anyone help?

Thank you for heading me in the right direction. I reset my Mail account for Outgoing Mail Server to outbound.att.net:(customer ID)@att.net (instead of smtp.att.yahoo.com, per Apple's online troubleshooting information). I'm not sure what "(Offline)" means when it appears at the end of my Outgoing Mail Server (SMTP)?? In the Advanced box I clicked on "Use custom port: 465" and checked "Use Secure Sockets Layer." Authentication: Password; I have correct User Name and Password put in. After doing all this, when I try to send emails again today, they go directly to the Outbox and sit there.
What's curious is that my first sent email this morning did go out using the Outgoing Mail Server, smtp.att.yahoo.com: (customer ID)@att.net(Offline) but subsequent emails I tried to send with this server were rejected with the message: "Cannot send message using the server smtp.att.yahoo.com (etc.). The SMTP server doesn't support TLS(SSL) on port 587. Verify your account settings and try again." That's when I tried resetting my Outgoing Mail Server to outbound.att.net (etc.), as mentioned above, and was unsuccessful in sending out any further emails. I guess my next step is to contact my email service provider, AT&T, and see if they can help me. Thanks, again, for taking the time to respond and for giving me your input! Much appreciated!

TS3276 why i can't see send email from iPad in mac book mail

hi,
i need help regarding using of MAIL 5.2, i am using the Mac Book pro Mac OS X. I am also using ipad 3 and Iphone 4s, now the question is if i send an email from my gmail account already configured in iphone 4s to any other email, then that send email should be displyed in my Mac Mail but it does not. At the same time i can see in ipad 3 that send email, but still can't see the send email in Mac Mail....?
please help me, how can i see all my emails send on Mail from Mac OS X?
Thanks and waiting

Sorry, I mean I can't see the folders in my hotmail account. It works fine with my iPad3, but my MacBook Pro has an issue with it...

Can no longer send email from my accounts but can receive

I have 5 email accounts set up on my imac. 3 are mine 2 are my partners. I can no longer send emails from my accounts but my partner still can. They all still receive mail but when I attempt to send mail I get:-
Cannot Send Message Using Server
Then i'm asked to select a different server from a list. I have tried all but to no avail.
I first of all deleted my partners sky.com account because it appeared to me that this was maybe overiding all other accounts and it was no longer needed on imac.
I then deleted one of my accounts - hotmail, to see if i added it again maybe it would work but now I cant even re add the mail account as everytime i go to mail, preferences account to set it up again the initial screen comes up with my partners details including the sky.com username and when i overwrite these and try to install hotmail acount I get told that logging in failed check user name and password is correct. Which they are.
All used to work fine but now I have these problems, they appeared to have started when my partner set up an icloud account and is synching with this - could this be the cause?
I can send email from my accounts from iphone still but no longer from imac.

First,
I'd run all availiable software updates. After that, I would try removing all of the accounts from "Mail", and then re-adding them. Be aware that if your folders and such are located on your mac, and not on the mail servers, you may risk lose some information (always have a back-up).
Sometimes, when you have a number of e-mail account there can be server issues abound. I would go into the server lists and make sure that they are set properly. If you see the "use only this server" box, check it for each of them.

TS3276 I cannot connect to my outgoing email server on my macBook pro, yet I can, for the same email account on my iPad. Also I can send emails from the other email account I have on my MacBook...really confused can anyone help?

I cannot connect to my outgoing email server on my macBook pro, yet I can, for the same email account on my iPad. Also I can send emails from the other email account I have on my MacBook...really confused can anyone help?

Sometimes deleting the account and then re-creating it can solve this issue
Write down all the information in accounts before doing this
Highlight the account on the left and click the minus button
Then click the plus button to add the new account and follow the prompts

I deleted my old Email account because I wanted to create a new one, and I did. However, when ever I send an Email from the Mail app on my laptop it says the Email was sent from my old Email and I just can not get rid of it.

I deleted my old Email and only used my new Email to set up the Mail app on my laptop. And the old Email is completely dead, hotmail.com says the Email no longer excists when I try to sign back in to it however my Emails remain saying 'Sent from Jordan [*old Email*].
I can't find a solution!!

If you are unable to remember your password, security questions, don’t have access to your rescue address or are unable to reset your password for whatever reason, your only option is to contact AppleCare(or Apple ID Support), upon speaking to an operator you should explain that your problem is related to your Apple ID, this way you will not be charged for assistance, even if you don’t have an AppleCare plan.
The operator will take you through some steps you may have already tried, however they need to be sure they have exhausted all usual approaches before trying to reset your account, so you should try to be helpful and show patience with the procedure.
The operator will need to verify they are speaking to the account holder and may ask you some questions that only the account holder could know, and you will need to answer them if the process is to proceed.
Once the operator has verified your identity they will send a message through to your device which contains an alpha numeric code, which you will need to read back to them.
Once this has been completed they will send an email to your iCloud email address after a period of 24 hours, so you should check that mail is enabled in your devices iCloud settings.
Upon receipt of the email, use the reset link provided to reset your password, after which you should be able to make the adjustments to iCloud that you wish to do.

The error I see is you did not specify the proper authentication for the smtp server.
In the Mail preferences for the account, smtp popup, select Edit SMTP Server List. A sheet will drop down. Select Advanced tab on that sheet. You should, I assume, set the Authentication to password, and set the proper username and password. That's where the poper would be set if 587 is not the one you should be using. Maybe it is. I only bring it up since I see it trying to use port 587.
If you got this stuff already set correctly then I don't know. Mail has a problem in your setup. Maybe delete the account and recreate it from scratch.

I am having trouble sending bulk emails (less than 100 at a time) on my gmail account using group names created from my address book. I use Mail on my I-Mac. When I try to send out a bulk email, the message shows up that my server can't send them, etc.

I am having trouble sending bulk emails from a Mail Group (less than 100 at a time) on my gmail account. They come back saying the server can't recognize the data and try again with selected server or try later or edit message, all of which I have attempted a number of times, including re-booting the computer. I am wondering if there is something wrong in my Address Book? I have check Apple Preferences, and Mail Preferences and all seems in order. I can send to any of the individual addresses, but not in a group.
Thanks for your help.
