Nodemailer not working on production [Micro]

[hexacris]

I created a micro for dispatch emails (expressjs), I added all the npm packages including nodemailer which is the common library for this purpose. On my local is work fine but when I deployed it, I updating the .env vars, the request is called from https://xxxxx.deta.dev but the email never was send. Exist some limit for mailing? micros are limited to return or send data only?
