Issue Adding Amazon WorkMail Account to Smartlead Too

The issue you're experiencing with adding your Amazon WorkMail account to Smartlead is likely related to a few factors, primarily the multi-factor authentication (MFA) you have enabled and potentially outdated TLS settings.

When MFA is enabled for Amazon WorkMail accounts, you cannot use your regular password to authenticate with email clients or third-party tools like Smartlead. Instead, you need to use personal access tokens. These tokens provide direct access to your Amazon WorkMail account and can be used for authentication with various email clients.

To resolve this issue, you should:

1. Create a personal access token in your Amazon WorkMail web client:

   • Go to Settings (gear icon) in the Amazon WorkMail web client
   • Choose "Personal access token"
   • Click "Create token"
   • Give it a name and create the token

2. Use this personal access token instead of your regular password when setting up your account in Smartlead.

Regarding the TLS issue, Amazon WorkMail has discontinued support for TLS 1.0 and 1.1. You must ensure that your connection is using TLS 1.2. Check if Smartlead supports TLS 1.2 for its SMTP connections.

For the SMTP and IMAP settings, your host addresses and ports seem correct. However, make sure you're using the correct region in the SMTP and IMAP hostnames (in your case, us-west-2).

If you continue to experience issues after trying these steps, you may need to contact Smartlead's support to ensure their system is compatible with Amazon WorkMail's security requirements, particularly regarding TLS 1.2 support and handling of personal access tokens for MFA-enabled accounts.
