Cannot Send Mail

[Brian19]

The connection to the outgoing server “mail.btinternet.com” failed. Additional outgoing mail servers can be configured

check your server settings here  https://www.bt.com/help/email/manage-email-account/manual-settings/what-are-the-settings-for-outgoin...

 what are you using to send mail bt app or using web mail?

[Brian19]

Hi I’m using web mail, and have tried previous suggestions to log in/out without success

[imjolly]

have you checked your mail server settings are correct with the link I posted

[Brian19]

Yes appears to be okay

[imjolly]

if using web mail have you tried a different browser

[gg30340]

You have said you are using webmail, that means you must be using a web browser yet when you are asked to check the server settings you replied that they are OK. 

You can not check the server settings in webmail (using a web browser) you can only check/change them using either an email client or email app so can you please clarify which you are using.

[Brian19]

Sorry appreciate your attempts to help me but I am confused with the jargon.

The settings must be ok as occasionally an email will send.

Also using Swan cctv which sends emails of detections using my btemail acct - again every few days this will work for a couple of hours then stop again.

i think it must be an outbox capacity related issue, imposed by bt ?
