- SMTP Control Swap : Dynamic SMTP server selection while sending an email message.

- SMTP Control per Location : Dynamic SMTP server selection based on detected location
Use Case Samples
When using Thunderbird on a mobile device (laptop PC), at home or at the office, not all the SMTP Servers are available. Some enterprises filter SMTP services to limit SPAM going outside, and the user must use the enterprise SMTP server to send the mail outside. While at home the user will have to use the service provider SMTP server.
SMTP Control Swap feature will give the ability to select the right SMTP server to send a mail depending on the situation, without changing the legacy default SMTP or user specific SMTP configuration.
SMTP Control Filtering feature will give the ability to configure, per mail account, which SMTP server might be used or not. For example you may not want to use, even by error, the enterprise SMTP gateway while sending a personal message on a mailing list about your favorite geek subject.
SMTP Control per Location feature will detect the current location (Home, Office, ...) based on user defined rules and current network settings. SMTP Control will then propose an outgoing SMTP server based on location.
