magento in not sending emails after host move

Question

I recently bought a vps hosting account for my magento store beacause it was getting to big for the old host (20000+ products). I did not change the ns for the domain yet because i want to be sure that everything works properly before the 48 h propagation downtime.

Among the things i observed is that magento is not sending any email to my customers, i mean any, not even the reset password email.

I'm baffled about this problem because the setting are all in order ( like my old old host ).

Does the fact that i dident change the ns has something to do it ?

================== EDIT =====================

managed to get it to send an confirmation email to the customer but cant get it to send copy of the mail to the admin.

Answer 1

yes, if your name server wasn't changed your MX records won't match. your emails are being discarded by your web host or something else in between because they are spam worthy until your MX records match.
