Mail SMTP

Hi,

I use WP-Mail-SMTP to send mails.

I was in local and i have put my site online.

I have the same settings in local and online.

SMTP host : SSL0.OVH.NET
SMTP port : 465
Encryption : SSL

When i send mail in local, i receive in few seconds.
But in online, i receive sometime in few seconds but sometime in an hour!!!

I contact my online host (OVH) but they said it’s not their fault…

Someone could explain me how i have this mistakes?

Thanks!
