If more than one Yahoo account I cannot send Yahoo emails with attachments.
Long story short I cannot send emails with attchments no matter how small if I have more than one Yahoo account.
W11 Thunderbird 128.2.1
In fault finding I have reinstalled TB and set up accouts for Gmail and Outlook with multiple accounts and all work correctly including Yahoo unless I have more than one Yahoo account.
If I set up more than one Yahoo account I lose the ability to send emails with attachments for Yahoo. To test: 1- No Yahoo accounts and cerificates removed from TB. 2-Set up one Yahoo account, accept certs and test by sending an email with an attachment. All Good. 3-Set up an addittional Yahoo account and test by sending an email with an attachment. Will Fail, server will time out eventually. 4-To regain sending with attachments > I have to delete all Yahoo accounts and remove the Certificte exceptions then recreate a single Yahoo account. Once I recreate a single Yahoo account and accept the Certificate exceptions I can then send emails with attachments. As long as I only have one Yahoo account.
Any ideas.

When you have multiple accounts on the same server, it's important to verify that there are as many smtp servers defined as the number of accounts, and each account is set to send on an smtp with a matching User Name. Have you confirmed this?

On a second, possibly related point, you shouldn't be seeing certificate errors if you follow the recommended practice of excluding the TB profile folder from AV scanning, and disable scanning of secure (SSL) connections.
Plus, confirm your Yahoo settings:
imap.mail.yahoo.com, 993, SSL/TLS, OAuth2, email address; smtp.mail.yahoo.com, 465, SSL/TLS, OAuth2, email address.

Yes, each account has a corresponding smtp with it's email address, Yahoo, Gmail, Outlook.

The certificate only happens with Yahoo on account setup. 4 popups for exceptions, all same. Only AV is Windows Defender, and have dissabled in the past and made no difference as I also tried in Safe mode and same.
These accounts have existed for years but I do not send many emails with attchments so I don't know when it started to fail. I can Receive text and attachment Yahoo emails and I can send text Yahoo emails, but I cannot send Yahoo emails with attachments if there is more than one account on TB.
I use Windows Defender and have never done any changes so I dn't know about scanning SSl connections.

Exactly as yours only POP and as created by TB on account creation.
I have a test PC with a clean w11 that I installed TB and setup two Yahoo accounts and I can send attachments. I then exported that profile and imported onto my main PC and it failed. I cannot send emails with attachments.
I have been at this for two days.
This is killing me. I just uninstalled TB and appdata TB folders and reinstalled. Created just one Yahoo account and now it can't send a Yahoo email with attachment as it could half an hour earlier. I'm done!
