Comments to SMTP credentials
It would be nice that we could add some comments to accounts at SMTP credentials. Now we have a list of accounts that was created years ago and I'm not sure where they are used. In this case if there are would any comment section I could enter that this account is used in CRM and this in website as example.

This is exactly what I was asking for to MailGun support - they forwarded me to feedback.mailgun.com.
Feature - Description / Comment / Additional text field in SMTP server record. I have seen this in other alternative services, and it was useful feature, because there is more information that must be stored together with SMTP Server so later you can filter or find the needed SMTP server by this information, or in my case even restricting/allowing access to credentials based on the information in description field - to not create duplicate SMTP server.By the way, while creating integration I came up with workaround solution for this problem! Maybe someone will find it useful while the feature is not implemented. So every time when creating new SMTP Server, I also create new route with same match_recipient as the SMTP Server login, I also need a route because of forward address, but the thing is that the route has Description field, so I can enter there the needed SMTP Server info, and when I need to know it, just find the route and read the field. What is good, that route record can be created without forward action, so it holds just this description info. To better understand result, I added screenshot. And offcourse you can filter routes by searching text in this description field and then understanding which SMTP server it is.
