-As an anti-spam policy, you **__MUST__** use a secure and authenticated method to send email through a third party email provider.  In fact, there are almost no mail providers today that will even allow you to send email via an unsecured method.  To use an email client like Outlook or Thunderbird, you will need to use their SMTP SUBMISSION port (tcp 587) or SMTPS (tcp 465) service.  You may also consider using their webmail service.  You cannot use outbound email service if it is only hosted on port 25.  Port 25 would allow a compromised PC to send out virtually unlimited spam.  See Hosting A Mail Server below.+As an anti-spam policy, you **__MUST__** use a secure and authenticated method to send email through a third party email provider.  In fact, there are almost no mail providers today that will even allow you to send email via an unsecured method.  To use an email client like Outlook or Thunderbird, you will need to use their SMTP SUBMISSION port (tcp 587) or SMTPS (tcp 465) service.  You may also consider using their webmail service.  You cannot use outbound email service if it is only hosted on port 25.  Port 25 would allow a compromised PC to send out virtually unlimited spam.  See [[knowledge_base:troubleshooting:portforwardingblocking#hosting_a_mail_server|Hosting A Mail Server]] below.

 Even if you do setup your mail server securely, we **__STRONGLY__** recommend that you do **__NOT__** do this.  We suggest looking into setting up a google apps account.  You literally must be an email expert to host a mail server correctly, and even then, much of the mail you send will probably be deleted by spam engines because they will know the mail is originating from a broadband account. Even if you do setup your mail server securely, we **__STRONGLY__** recommend that you do **__NOT__** do this.  We suggest looking into setting up a google apps account.  You literally must be an email expert to host a mail server correctly, and even then, much of the mail you send will probably be deleted by spam engines because they will know the mail is originating from a broadband account.
