500 line limit exceeded

[larte_e_vita]

Hi !

With my last newsletter I've got this smtp error code "500 line limit exceeded"

I use the smtp of 1and1 (because I have a website on it) and till now without any problem.
I ask them for that error code and they have no idea about it.

Help me please. :?

Is the Singly option activated on the settings panel?

 

[larte_e_vita]

No, usually I set a group of 5

Singly is the solution?

I forget to notice:

When I use another Smtp as smtp.free.fr, I don't get this error code...

That can be a delivery error per hour or per day, or a delivery limit per session. You should reactivate the singly option and see if it fixes the problem.
