I'm using Nodemailer for a website, and everything works fine emails get sent. The website and email is on Ionos. After a few days though I always get a warning message on the Email account that it has detected strange activity on the account and I have to change the password, if I ignore the message I can't send or receive any further Email.
Is this a common problem with Nodemailer? Is there a way to prevent this or is there a better mail solution I could use where it's less of a chance of this happening?
