I am a new ZohoMail user. I am just creating a small business domain with couple of emails. During my internal tests today there is anoying delay in recieving emails in Zoho (both through mail.zoho.com, and an external client). The delay is between 15 minutes to 2 hours. Previously I was using the business app from google and there was no problems with delay in recieving mails. Do you have some issues regarding this or the problem is by my side? What should I check. Below please find the hedder from last test mail. According to the header the email was recieved by mx.zohomail.com at 10:05:15 (PST) so  3 seconds after sending, but it "came" to the inbox approx. at 10:16 (PST) - (19:16 local time). During the day the delay was much worse.
