The GoSMTP team has released version 1.0.4.
This version has many improvements for the GoSMTP.
The following is a list of changes :
1) [Bug-Fix] In some cases, the recipient's email was not configured properly with SendLayer Mailer. This is fixed.
2) [Bug-Fix] In some cases, the AmazonSES mailer secret key was not implemented correctly. This is fixed.
We will be launching many more changes in the upcoming version.
