Hi Guys, 
Right now I have one ploblem with emailalerts.

 

I have 3 costumers, with exactly same info, but with 4 different emails:

 

1) email: [user]@gmail.com

2) email: [user]@critec.pt

3) email: [user]@outlook.com

4) email: [user]@nexus-pt.eu

 

and the email order for webmaster is only sent if the order was from user 1)... from others, order is submitted but the email isn't send.
But if I change one from other emails for an gmail account, the email is sended.

 

Someone already has the same problem
