Multiple SMTP Servers for any type of email address?

Hello I was wondering about a way to put in custom email addresses and smtp servers for various email service providers.

name_xls =  num2str(filenamev1);
name_xls2 = [name_xls '.xls'];
xlswrite(name_xls, exceloutput, 'Sheet1','A1');

%Emails Excel sheet.
promptemail = menu( 'Email', 'Yes, email my results to my email!', 'No, I do not wish to email my results at this time.');

%Emails Excel sheet.
if promptemail==1
h = warndlg('Make sure your computer is connected to a secure Wifi connection! e.g: UCLA_WIFI, home network, etc. or disable your firewall!');
waitfor(h);
filepath = fullfile(pwd, name_xls2);

% Define a title for the dialog box
dialogtitle = 'Email Credentials';
% Define the labels for the individual entries
emailinfo = {'Email Address'};
% Create the dialog box with the inputdlg command
z = inputdlg(emailinfo, dialogtitle);
waitfor(z);
password = passcode; 
setpref('Internet','SMTP_Server','smtp.gmail.com');
setpref('Internet','E_mail',z{1});
setpref('Internet','SMTP_Username',z{1});
setpref('Internet','SMTP_Password',password);
props = java.lang.System.getProperties;
props.setProperty('mail.smtp.auth','true');
props.setProperty('mail.smtp.socketFactory.class', 'javax.net.ssl.SSLSocketFactory');
props.setProperty('mail.smtp.socketFactory.port','465');
sendmail(z{1},['LFA Analysis for: ' num2str(filenamev1)] , 'Here are the results for your analysis!', filepath) 
else  
end 
warndlg('Done!');

Yes. Just detect which email service provider you are using with strfind() and take action (set custom email addresses and smtp servers) based on which providers you find.

Hi, I am not able to run above code getting an error Error in Untitled12 (line 1) name_xls = num2str(filenamev1); Do I need to enter any value here

What is your error message? What value did you assign to filenamev1? Or did you not do that, in which case it will say something about filenamev1 not being defined. What is the complete error message (you forgot to post it!!!)?
