Why won't my emails actually send?

more options

I have the same settings for my website's email address (faye@fayebryant.com) on Thunderbird as I do on my phone's email client. HOWEVER, while I can both send and receive on my phone, when I send with Thunderbird, the email shows up in my sent folder on TB and on webmail, but it does not land in the inbox it was sent to.

Very frustrating!

Chosen solution

WOOHOO!

I restarted Thunderbird with the add-ons disabled. Lo and behold, email sent without a problem. So, I tested and added each add-on back, one at a time, to see if I could determine the culprit.

It was my readnotify read receipts! I had not added this email address to the list of emails to use and it was blocking the send. Now it's added and the email is working.

Thank you again, Mozilla peeps, for your assistance!

I tried all that. Multiple times. Nothing has worked.

Try sending while in your operating systems safe mode:

If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates.

Mail went through when I was in the safe network mode. Thank you, Matt!

Now... how do I track down what is causing the problem? The other email addresses I use are able to send just fine. Why would one thing be stopping one email smtp, but not the other?

I'm so confused.

I have the same problem (all of a sudden).

Send Message Error:

Sending of message failed. The message could not be sent because the connection to SMTP server smtp.mail.me.com timed out. Try again or contact your network administrator.

They send with Mac in safe mode ok. I've disabled all plug-ins and it still doesn't work.

This happens to both my email accounts. My 'iCloud' account and my own domain account.

Any help gratefully received..

Rick, it would have been better for you to ask your own question. But in the interest of getting things done, try disabling any anti virus you have and see if that helps.

It would be more likely to be extensions blocking sending, not plugins.

I don't (apparently), have any add-ons or extensions installed just 11 plug-ins. All disabled.. Thanks.

After numerous configuration attempts over the last few days, my iCloud AND own domain email accounts finally work. Sadly I don't even know what I did to maybe help others but obviously a combination of settings solved it.

I've re-activated all 11 plug-ins in Thunderbird an email's still working, so not that then..!

Thanks for all your help everyone!!

News Flash!

I think through just luck, yesterday I managed to enter the correct settings in Thunderbird for my email to work. (Images of settings below) - All emails were coming in and going out fine.

This morning, same problem's back. I can receive but can't send. I haven't touched anything at all or downloaded anything. I haven't even used my computer!

Ther MUST be a serious issue with Thunderbird...

Or a problem with the server.

How do you post a question on this forum? It keeps sending me round in circles offering questions I don't want to ask!

I want to post my problem in the Thunderbird section and not ask a question Mozilla suggests for me!!

Unuser-friendly forum. I think I've set myself up as a 'contributor' and not a regular punter!!

Any help please..!!!

I have found that I have to use a non-Mozilla browser to ask questions on this forum, so I use Safari. Mozilla browsers are fine for answering questions here, but not for asking.

Well that doesn't give me much faith about Mozilla's products. This is really a strange forum.. Maybe I should've ditched Thunderbird on day one!!
