Why is my mom having trouble sending SMTP emails with Thunderbird, but it works for me?

Asked by MissAnthrope (21474points) February 17th, 2011

I just spent the past hour and a half doing Thunderbird tech support for my mom and my head hurts! I cannot for the life of me figure out why these email settings work for me and not her.

I created a GoDaddy email account for her rental property. We’ve followed GoDaddy’s Thunderbird instructions, as well as going with the automatic settings provided by Mozilla’s ISP database. My ISP is here in the U.S. and my mom uses an Italian one.

While setting up the account in TB, it took me mere seconds, just click-click-click and it worked. With her, nothing we have tried works and trust me, as far as I can tell, everything is set correctly. She also has a couple of Yahoo! Plus email accounts that I set up ages ago and which work just fine.

She can receive mail on this account, but she gets the following error messages when she tries sending:

“Sending of message failed. Please verify that your mail and newsgroups account settings are correct and try again.”

“Message could not be sent using SMTP server for an unknown reason. Please verify that your SMTP server settings are correct.”

I find it really weird that I’m able to use the same exact settings (and my version of TB has one of her Yahoo accounts, as well, so the environment is almost the same) and she can’t.

Please help me.. I think my head is going to explode. :)

Maybe she’s got a firewall that’s blocking the port needed for secure smtp? That’d be unusual, but it’s the best guess I have at the moment.

I thought that, too.. we’ve tried several different ports (listed by GoDaddy as acceptable alternatives), as well as switching it from SSL to no SSL (and changing port numbers there, too). :\

Then I only have this question to ask, and I apologize in advance: you set her login name to include her domain, right? like ?

Yep. I have my version set identically to hers.. mine works perfectly. Hers gets the error. It’s just so weird. I’d be apt to blame it on her ISP, but then her Yahoo messaging works fine.

Thank you for your help. I’m at the end of my rope and have no idea what else to try. I mean, port 80 should work for sure, as that’s usually web/browser port and I know that works fine for her otherwise. I’ve posted on the Mozilla support forums, but no one has responded.

The Yahoo! email also uses the same ports for SMTP? Because the only other thing I could think of, and it would be a stretch, is that the government has certain encryption things locked down. That’s really reaching, though.

Hmmmm. Well, her ISP does have a ridiculous firewall that has, in the past, interfered with other programs such as Flickr Uploader. So, it’s not out of the realm of possibility.. just strange that the Yahoo account is set (and I believe with SSL) and works and the other one doesn’t.

The other thing is, have you looked at her email account in the GoDaddy control panel and made sure she has SMTP relays set? I think the default is 250, so it should be good. But you never know.

Yes, if you can’t tell I am an email support geek:
The autodiscovery service may resolve differently in Italy. What comes up during an initial account setup in Thunderbird? You can try Outlook Express to rule out Thunderbird, but I don’t think it’s a client issue, but one never knows.
The fact that she receives ok shows that the authentication name and password are right.
The US autodiscovery is:
as you listed Port 465 Normal Authentication SSL/TLS
This may be different for here ISP or Country.
Sounds like you tried a few of these but one wrong setting
Without SSL
Incoming Port
IMAP – 143
POP – 110
Outgoing (SMTP) port
One of the following: 25, 80, 3535, 587
With SSL
Incoming Port
IMAP – 993
POP – 995
Outgoing (SMTP) port
If it is hosted Exchange then your settings are:
Incoming Mail Server
Type for your incoming mail server.
Outgoing Mail Server
Type for your outgoing mail server. (NOTE: This applies to POP3 and IMAP.)

Hit me up in a message if you want to go over it differently.

@mrentropy – It took me forever to figure out where the heck that would show, but I got it finally. Yep, 250 relays. :)

@blueiiznh – Thank you for chiming in! She’s now in bed, but I will add this info to my arsenal for when I get to do this all over again tomorrow. Ugh. :\

There is a manual way of testing their smtp service port by using telnet if you really need to. Let me know.

MissAnthrope's avatar

I really appreciate the help so far..

@blueiiznh – None of that worked.. I’ve tried every combination possible. I guess I’m going to have to call GoDaddy to see if I’m missing something. :\
