[horde] outgoing server e-mail

[marta at gostudy.com.au]

Dear List,

I'm trying to access my horde email using Outlook in Brazil but I am  
having problems sending the emails. This is the text that appears:

The message could not be sent. The configuration of authentication may  
be incorrect for the outgoing server e-mail [SMTP]. For help on how to  
resolve this problem, go to Help, search for "Troubleshoot Windows  
Mail" and read the section titled "Issues to send email." If you need  
help to determine the appropriate configurations of the server,  
contact your email service provider.

The rejected e-mail address was' marta at gostudy.com.au '. Subject  
'test', Account: 'Marta', Server: 'smtp.ig.com.br', Protocol: SMTP,  
Server Response:'530 5.7.0 Must issue a STARTTLS command first.  
2sm1488894aga.3 ', Port: 25, Secure (SSL): No, Server Error: 530, No  
of error: 0x800CCC78



I already double check with my internet provider, and they told me  
that?s nothing they could do for me.

Can someone please help me in this matter?


Thanks Marta
