eMail notifications: Explicit port setting

[SeanAdams]

The eMail setup for the eMail tool and the eMail notifications are subtly different - in that the eMail notifications screen does not offer an explicit location for port.    This is important if the SMTP server does not use the default port.   You may be able to do this with : notation, but it would be better to create an explicit field for this.

No Port available on the eMail settings for EventsPort is available on eMail tool
