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?

Who is the provider of your email account and to which ISP are you connected via wireless ?

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

Mine worked when I added my user name and password in the outgoing mail server section. I didn't make any other changes. Hope this helps. I have cox.

Was that your cox account name and password? Or your 'external' smtp server password
