SMTP Port 587 Settings For Outgoing Email

In an effort to increase email security, Netrepid/PA Online will be making a change to the way that all of our customers send email.


Currently, it is possible to send out an email without authenticating to the mail server. With this configuration, it is possible for a spammer to log into the mail server and send out mass emailings which can slow down the sever and cause delays in the delivery of mail.

PA Online was acquired by Netrepid, Inc. in June 2009.

Starting on November 4th, 2012, we will be setting the server so that all customers will need to authenticate whenever sending an email message. The change that you will need to make to your mail program should only take about 5 minutes, and will only need to be done once. After the change, the process will be automatic.


If you currently use our webmail service to send and receive email, you do not need to make any changes. If you use a smartphone such as an iPhone or Android, you will not need to make any changes. If your internet connction is through another company such as Comcast or Verizon, you are already configured properly and will not need to make these changes. If you have any issues making these changes, please contact technical support and we will be happy to walk you through. We do strongly advise making these changes before November 4th, 2012.
