c# - System.Net.Sockets.SocketException when app is in network -


so trying send email in app standard code:

mailmessage mail = new mailmessage(); smtpclient client = new smtpclient(); client.port = 25; client.deliverymethod = smtpdeliverymethod.network; client.usedefaultcredentials = false; client.host = "mail.mycompany.es"; client.credentials = new networkcredential("myuser", "somepass"); mail.to.add(new mailaddress("somemail@gmail.com")); mail.from = new mailaddress("me@mycompany.es"); mail.subject = "this test email."; mail.body = "this test email body"; client.send(mail);

and worked in debug mode, released , placed .exe on shared drive.

if execute there, gives me following exception:

[system.net.sockets.socketexception] = {"an invalid argument supplied"}

so must kind of permissions error, don't know how can solve it.

full exception dump:

system.net.mail.smtpexception: error al enviar correo.
