I'm getting an error about Plaintext Authentication not being allow

Using non-encrypted logins presents both a security threat to our servers and clients, but to the users as well. It's only a matter of time before someone is able to monitor the traffic from your computer and obtain your password, and then be able to use your email account to send out spam and emails representing themselves as you, or even read your email and gain access to other accounts and personal information.

Using non-encrypted logins for email presents an easy opportunity for identity theft and expensive cleanup bills from us if your account is compromised. We have been advising clients to use SSL encrypted logins for several years now.  Initially, it was most important for mobile connections as it was only a matter of time when using wifi that your password would be captured by a hacker. However, with recent router malware and other security vulnerabilities, it is important to always encrypt your logins where possible.

On August 14, 2018 we began the first stage of not permitting non-encrypted logins to our mail servers. During this stage, we discovered that many email clients were still using non-encrypted logins. We have rescheduled the final phase of turning off the ability to pick up or send email with a non-encrypted login for September 10, 2018.  If you are still using non-encrypted logins at that time, you will get errors when trying to pick or send email until you make the required changes to your email configuration. This applies only to clients using V3 for email services.


In order to be compliant with the security changes you will need to ensure that your incoming mail settings are as follows:

  • If you are using IMAP: port should be set to 993 and ensure that SSL is enabled
  • If you are using POP3: port should be set to 995 and ensure that SSL is enabled


If your outgoing mail uses V3 servers, you will need to ensure that your outgoing (SMTP) mail settings are as follows:

  • Port should be set 465, SSL should be enabled, and Authentication turned on


For additional information regarding your particular software, you may need to use Google or contact your IT support for verification.   About 95% of all of our users are compliant already but some software auto-configured to non-SSL connections and need to be updated.
