why are my emails not being delivered?

[lagarto1989]

I've been using roundcube for about one year and everything was fine until now!

every single email that I try to send does not get delivered, and I have to use my personal gmail to contact who ever i'm trying to send an email to.
the only emails that do get delivered are to a gmail address.

Can I get some help please!

thanks.

Why are the messages getting delivered? What happens when you send a message? Are there any errors? Need more information to help.
