I'm just starting to implement zoho as my MX provider, but I'm having trouble authenticating the smtp server. I'm using the IMAP protocol and my email client is Airmail 3.0. I set up the MX servers at Go Daddy and can receive incoming emails, but I can't figure out the proper setting for outgoing mail.

Per the IMAP settings instructions, I have smtp.zoho.com as the SMTP server. I've entered the email address of me@mydomain.com as the User and entered in my password. However, I can't authenticate and send emails.

Need a little help. Suggestions on what I'm doing wrong and things I can try to remedy?

Thanks,
