support for RFC 6531

[Peter]

Hi,

Could you please add support for UTF8 in email addresses?
For example: café@example.com

Please tell me, if you need some funding for implementing this feature.

TIA for your help. Kind regards, Peter

What are you looking for in the way of support? Presumably you want to be able to subscribe UTF-8 encoded addresses with non-ascii. Do you also want to allow non-ascii list names?

I would be inclined to only support this as a site option. Should it also be contingent on the outgoing MTA offering SMTPUTF8?

I'm sure we will have to support this at some point in Mailman 3, but it may not ever be in Mailman 2.1.

Yes, but it's less important.

Yes, this is the feature, I'm looking for.

Ok.

Yes, this makes sense. (Postfix supports it without problems.)

I would like to see this feature as soon as possible in Mailman 3.
Funding is possible.

It would be good to submit this issue at https://gitlab.com/mailman/mailman/issues/ for Mailman 3.

Ok, done.
