Mail "Proccesing" and won´t send

Whenever I send an email it goes directly to my sent folder and says "Processing" if I refresh the page the message dissapears and the email doesnt have any indicator of it being "In line" or "Sent correctly".

Need help because I alredy sent an email to supportzohomail[dot]com and it doesnt go through.

The mail covers a very important process and need it working.
