Glad to know you managed to fix it. > (defun rcd-mailutils-mail-files (files) Nice function. Congratulations! I hope that "mail" will someday be able to process UTF-8 headers and names without additional hassle. > It means servers are giving wrong information about email addresses > while the real problem is with file names. Allow me to draw your attention to the fact that the reply from the server was not implying that the problem was in email *addresses*. On the contrary, it said: 553-The recipient's mail server does not support E-mail 553-messages with international Unicode E-mail addresses or 553-E-mail messages in the international Unicode E-mail format. Note the 'or' clause: in other words, it was trying to tell you that it is unable to process mails formatted as per RFC 6532[1].
