I generally send apk files (zipped) to my contacts from my zoho mail account. Since yesterday it is failing to send it. Either emails are not going to the receiver or going with 0KB attachments.
I can send the same file from my gmail account fine to other accounts. But for testing if I send the same file from my gmail account to zoho account, then it is bouncing.
Is there any change on zoho email server this week? Why is zoho email account behaving differently from my other email service accounts?
