If you have a DSL account with us, you should use mail.binary.net as the incoming (POP3 or IMAP4) mail server and smtp.binary.net as the outgoing (SMTP) mail server.
If you have a virtual host at Binary Net you should use mail.yourdomain.com as the incoming (POP3 or IMAP4) mail server. For an outgoing mail server it is best if you can use the SMTP server of your local Internet service provider (ISP). We do offer an SMTP authentication server that will work with any ISP. Use smtp-auth.binary.net as the outgoing mail server along with the same username/password as the incoming mail settings.
Please check the manuals of your email client for instructions of where to customize your mail settings.
Please contact us if you have any further questions.
