Hello,
I reviewed Nest Mailer and this module uses Nodemailer but did not give options to add the Nodemailer module. We have to either modify nest Mailer code or extend MailService of Nest Module if allowed. I have experience in NodeJS, NestJS, TypeScript, Nodemailer, and I can help you to add Nodemailer's Openpgp module. Let me know when we can discuss.
I am Sr. full stack developer & DevOps with 6+ years of experience. I have experience in Java, JavaScript, NodeJS, ExpressJS, AngularJS, Angular, GraphQL, RESTful, MongoDB, MySQL, PostgreSQL, Linux, Nginx, Apache, AWS, Git, etc.
Looking forward to working with you.
Thanks
