Hello zoho team. first i want to thank you for your hard work.. 

Second i have a doubt about the time it takes to send mails with attached files (2-4mb those i tested), it takes around 2 minutes.. im using thunderbird, outgoing server smtp.zoho.com, with godaddy.

I just want to know if thats normal

Let me know if you need some additional info to help me.

Thanks in advance for your attention..
