Failed to send: Can't send mail - all recipients were rejected

marcusjusa

Outgoing emails on my desktop get stuck in the outbox and will not send. No error code is given just that it failed to send. I enabled the log and it said "Failed to send: Can't send mail - all recipients were rejected." But, the email address is correct and I even trying sending to my own Gmail account and that had the same result.

I receive messages with no problem. I haven't used Vivaldi Mail recently so I suspect some update with Vivaldi or Windows 11 may be the issue.

My outgoing server settings are: smtp.vivaldi.net; 465; SSL/TLS; [My user name and password]

There is a green "verified" box and checkmark.

Can someone help me and explain it like you would to a novice? Thanks.

First of all,
Restart Vivaldi and the OS.

Thanks for the quick reply.
Vivaldi version: 6.5.3206.57
Started today but I have not sent mail using Vivaldi for a couple of years.
Windows 11 Home version 23H2

I deleted Vivaldi Webmail cookies and site data and Vivaldi cache. None of those steps resolved the problem.

I did not "clean service workers." I have no idea what that is (remember I am a novice). I did not reset flags. As a novice, I do not know what those are.

I also closed out everything and restarted my computer but the problem persists.

Hi, I can send from my vivaldi.net account but some recipients may not trust Vivaldi and block it. Iirc Microsoft do so but Google not.
A third party security software can block anything in Vivaldi, on a friends PC, Avast block email accounts, for example.

Cheers, mib

marcusjusa

Good suggestion. The only third party security software I have is uBlock and Vivaldi is on the exception list.

Hm, I meant on OS level, Defender does nothing to Vivaldi all others can do.
It is a bit strange, can you test this with the web client?
mail.vivaldi.net

Cheers, mib

It will not send on the web client either. I tried sending to my Gmail account and I received an error message: "SMTP Error (554): Failed to add recipient "[email protected]" (5.7.1 <[email protected]>: Sender address rejected: Access denied)."

I would not publish you gmail address.
Send you a mail to your vivaldi.net and Gmail account.

marcusjusa

I received one email from you at my gmail account at 26 minutes after the hour (not sure what time zone you are in). The text was "And another one."

marcusjusa

I also received an email from you in Vivaldi mail.

@marcusjusa
OK, vivaldi.net is sometimes slow but it work.
May you get get more information if you change the log level.
Type "biscuit" in the settings search field and set log level to "Debug".

Send a mail, check the logs from the status bar mail icon and save it to a text file
Set log level back to warn, debug create a lot of messages.
Past the log to https://www.toptal.com/developers/hastebin or other text file hoster.
Add the link link here, maybe we can help then.

I pasted it here because it's only a few lines, thought it were much more.
A user post this error was a profile issue:

https://forum.vivaldi.net/topic/90117/solved-persistent-notification-can-t-send-mail-all-recipients-rejected

You can create a second profile and test this or remove the account with delete all mails and add it again.
This is not working with a POP3 account but no problem with IMAP.
Maybe another user have a better idea but I would do so.

Cheers, mib

marcusjusa

Thanks. I tried a second profile and that did not work. Unfortunately, I think I will not continue using Vivaldi mail unless someone has another Idea I could try.
