Cannot Send Mail Sender Address Invalid

when replying to an email, I receive this message. It is a POP3 account. I've experienced this in the iPod touch and reset the touch, it worked. Tried the same in the iPad, no luck. I've checked and rechecked that the smtp address is correct. I can receive but not send..help

G5, Mac OS X (10.5.5)

This might also mean the email address you are sending to is not valid. Have you checked that?

If it still applies Cox were known for blocking Port 25 which email uses and people only had access to webmail.

Have you had other computers accessing mail other than through webmail or have you always used webmail before the iPad?

I use an iMac , and iPod touch to retrieve my mail, not the web mail site. I just tested my iPod touch by sending an email and worked perfect as did the desktop

I had the same issue. I left the userid and password fields blank, saved the configuration and voila, I was able to send. Give it a try.

I have the same problem with POP accounts (@mac account works well). Not in Cox network. All works well on both Macbook and iPhone but not iPad. Called apple support but after long discussions I got "disconnected" with no answer. Any fixes?

I called and spoke with Apple at Apple Care.

Reset your iPad by holding the home key and power button simultaneously, wait for it to reset then, go to:

Settings>Mail,Contact,Calendars>select your email acct.>Advanced>Authentication>Password
Also under the Advanced, make sure "Use SSL" is turned on

Mine has worked perfect since Sunday morning.

mine fixed by doing what aahmie suggested AND adding my username and password in the "outgoing mail server" info, even though it says "optional" (same username and pw that's listed in my "incoming mail server"). Works great now.

You can, for a around $15/yr., send up to 150 emails a day over wifi using an independent outbound SMTP server ... works GREAT for Cox with my iPad, iPhone and laptop. I use a service from dyndns.com One account will service multiple email addresses too.

Very easy to set up the devices.

I did the same and it works! I did not need to turn SSL on.
