Hi ,

Recently, every time I send a letter to Yahoo's mailbox, I will receive an error letter, which says "554 Message not allowed - [299]". Does anyone face this problem before, I couldn't send email to any yahoo mailbox now...

Thanks!

Hi @TONYCHOU81905

Is this something others could possibly encounter as well?

If yes, what was the problem?
