Can the postalserver set up sender and receiver email avatars?

[wangyuanchen]

I have a requirement here that I need to set up a avatar for sending and receiving emails, but I don't see this feature in the configuration description. I'm not sure if it's a problem with my usage or if it's currently not possible to set avatar information. May I ask for your advice now？

Avatars aren't part of the message, they are added by the receiving email software using Gravatar (or similar if there are any other options).
