Outgoing email nog working

Outgoing email nog working

Hi, 

I can't get my email to work in Bigin. Incoming email comes in fine but I can't get it to sent and it gives me this message (dutch version): 

Fout bij verzenden van e-mail

Maybe it is because my incoming and outgoing server are not the same and both have different passwords but I can't put in the password for the outgoing server. Is there a way to put in the needed password or is there a simpler way to get things going. 

Thank you in advance for your help. 

Tamara
