smtp server and outlook or thunderbird

Hello,

First of all thank you for that Great tool.

Well i m having trouble when trying to configures mails on outlook and thunderbird the problem is im having trouble to connect to smtp server in both clients !

When using Roundcube or squirre i can connect send mail receive them.

but on the client i only can receive them cause of the smtp server.

Server : aicha.batata-dz.com (where's the main installation)
website : www.batata-dz.com it's a website managed by ehcp.

i tried all mail server aliases such as : mail.batata-dz.com, email.batata-dz.com, webmail.batata-dz.com, batata-dz.com, aicha.batata-dz.com

here is a test account mail : test@batata-dz.com
pass : ehcp

Thank you for responses
