Error Catch In SQL

Hi everyone, I am using an SQL extended stored procedure to send emails in a
DTS package using a cursor that goes through each row in a table.

Email sending code below
======================
exec master.dbo.xp_smtp_sendmail
@FROM = @sFrom,
@FROM_NAME = @sFrom,
@TO = @sRecepients,
@subject = @sSubject,
@message = @sBody,
@type = N'text/html',
@codepage = 0,
@server =N'MYMAILSERVER'
======================
Fetch Next From EmailCursor ...

Now the problem I have is that if an individual email address in invalid
then an error occurs and the whole DTS package falls over. What I would like
to be able to do is "catch the error", something like this (C# code used as
example)

try
{
exec master.dbo.xp_smtp_sendmail
@FROM = @sFrom,
@FROM_NAME = @sFrom,
@TO = @sRecepients,
@subject = @sSubject,
@message = @sBody,
@type = N'text/html',
@codepage = 0,
@server =N'MYMAILSERVER'
} catch {
exec master.dbo.xp_smtp_sendmail
@FROM = "arealaddress@mybusiness.com",
@FROM_NAME = @sFrom,
@TO = @sRecepients,
@subject = @sSubject,
@message = @sBody,
@type = N'text/html',
@codepage = 0,
@server =N'MYMAILSERVER'
}

Is this possible??? Normally I would do all the email validation before the
email is entered into the database but unfortunately, I do not have access
to the application code so I am stuck doing it this way.

Thanks in advance
Mark
