头像为电子邮件地址 [英] Avatar for an email address

问题描述

确定，我不知道这个问题甚至属于这里，但这里... ...

OK, I'm not sure this question even belongs here but here goes...

我有一个电子邮件服务器运行Postfix和Dovecot和几个邮箱那里。使用像Gmail或Outlook这样的第三方电子邮件服务，我注意到他们为某些电子邮件获取头像。问题是如何在我自己的服务器上附加一个头像到我自己的邮箱，以便其他人识别他们？这是邮件协议的一部分，我可以以某种方式设置，还是应该使用任何第三方服务？

I have an email server running Postfix and Dovecot and a couple of mailboxes there. Using third party email services like Gmail or Outlook I've noticed they fetch an avatars for some emails. Question is how can I attach an avatar to my own mailboxes on my own server such that others will recognize them? Is this a part of mail protocols that I can set up somehow or should I use any third-party services?

推荐答案

头像是由邮件客户端处理，而不是邮件服务器。 Gmail提取@ gmail.com的Google +头像和Microsoft全球交流通讯录中的outlook fetchs avatar。
AFAIK没有电子邮件头像的协议，也不容易将第三方集成到Gmail或Outlook中。

Avatars are handled by mail client, not mail server. Gmail fetchs google+ avatars for @gmail.com and outlook fetchs avatar from a Microsoft global exchange address book. AFAIK there is no protocol for email avatars and no easily possible 3rd party integration into gmail or outlook.
