Description Frank Büttner 2015-12-05 11:35:27 EST
Description of problem:
Using evolution for IDN mail domains is not possible, because the support is incomplete.

Version-Release number of selected component (if applicable):

How reproducible:
Send an mail from an IDN mail account.

Steps to Reproduce:
1. Add an new mail account for an IDN like foo@müller.de
2. send an mail

Actual results:
The mails is reject by the receiver, because the header are incorrect.  

Expected results:
Send mails will work.

Additional info:
When I look in the source code of the mail, all header field, will contain the IDN and not the puny code version of the mail domain.
The RCPT TO:<XXX> stuff while transmit is correct. Here the IDN will be translated to puny code.
Comment 1 Milan Crha 2015-12-14 08:41:21 EST
Thanks for a bug report. This wasn't discussed much in the time of the fix for an upstream bug [1], though I think the message headers are not supposed to be puny-coded, the puny-fication of the headers is left up to the clients. I do not know why the receiver rejects the message, especially when the SMTP sending part in the evolution tells the SMTP server to use the puny-fied version of the domains.

As you mention RCPT TO:, I suppose you use SMTP too.

Do you know the exact error message with which the receiving part rejected the message, please?
