The sender address was invalid

I got an iPod Touch since September 2007. No problem at all with the email account until the version 2 update software. I receive all my email on it but unable to send email, from gmail account, from my internet service provider email account etc... All email account I cannot send email.

Then I receive my new iPhone today, I was hoping not having the same problem. But I got the same problem, not able to send email. And I got this message: The sender address was invalid.

How can my address email can be invalid when it come from a reply or my address book.

Also the setting was not made by me, because my email account was sync from my powermac G5 and I can send email from my computer.

now I have two mobile device that can't send any email.

Any idea???

I upgrade to 2.0.1 the iPhone and can't send email again

I'm having the same problem over here. It worked fine last night but this morning without changing any settings it stopped working for Gmail on my iPod touch.

It seems odd that this happened suddenly at the same time for everyone here (me too!)... it must be an issue with Google's SMTP server (?)

I hope a solution (that does not require disabling authentication) is found soon.

I'm on an iPod Touch BTW...

Like others, this problem started for me today. I thought it was related to the 2.2 update, since i only noticed it after the update, but now it looks like the problem is more likely to be related to the Gmail smtp servers. Hopefully this gets fixed soon before everyone screws around with their settings too much, and everything ends up borked after Google or Apple fixes the issue...

This is happening for many Rogers carrier users in Toronto -- with gmail as the smtp gateway.

Looks like a gmail smtp server issue -- if happening for folks using different carriers.

Well it worked with the stuff above just fine.. but it stopped saving the sent messages.. it only saved the ones send to the same account...Maybe all this has to do with the new update [2.2]. Since we are all getting it in the same time ... maybe thats the coincidence.... I just update it and restored my iPhone and its the same.... i have no idea why its like this

This is not just related to gmail servers. My Yahoo mail on my iphone is having the same problem even after I deleted the yahoo account and reinstall them on iphone, I get the "Sender address was Invalid" message and all messages could not be sent. This is the same for both WiFi and 3G network. I only have this problem since I updated to the iPhone 2.2 and iTune 8.0.2 yesterday.

Come on, Apple. The last time you gave us the iPhone 2.1 update it messed up my e-mail fetch feature (it wouldn't fetch my gmail), and now this !?!!?

Same here.

Just downloaded and installed 2.2 today and I'm having the same issues.

I was having a similar issue with my iPhone 3G yesterday after upgrading to the 2.2 update. I switched to the at&t smtp for the evening, woke up this morning and switched back to the gmail smtp and everything is working fine. I'm on the east coast, but still hearing that canada and abroad is has yet to resolve the issues.

Everything is back to normal. The primary server works perfect - like it used to. I'm with Rogers (Canada) .. Looks like everyhting is fixed

Weirdy... I reverted back to the original configuration (port 587 by the way, made a mistake) and it works fine today. SSL can be ON or OFF, it works. So I guess it was just an issue on Gmail's side.

I had the same problem and here is the fix. 1) goto setting 2) click on mail, contact, calendar 3)select your email acct 4) click on SMTP 5) click on the first box under primary server 6) make sure you type in your user name and password.

My issue was that these two field were left blank and my service provider changed their setting and now you need to make sure its in your setting.

I hope this helps

My god!!! It worked!!! I have been trying absolutely EVERYTHING to fix this for about two weeks, and the "recipient address invalid" problem, and changing to port 25 the message suddenly went!!!

Three out of 4 problems fixed, now just need to get the mobileme account working!

Thanks!

Thank you for sharing this. This has been bugging me for a while, and I just googled the error message and found your answer.

Works like a charm!
