Encoding of from_full_name

[Rutherther]

Hi,

I wanted to use from_full_name along with set_from_header on. Since my name contains some czech characters, I put them in the full name. These can be áéíóúžščřěů. The e-mails I sent were displaying with wrong characters in name in other clients that eventually received them via IMAP. I am not completely sure if this is problem of msmtp or opensmtpd that was likely trying to translate these to smtputf8 - in K-9 mail on Android I see the sender as =?utf-8?B?...=?=`.

I've tried playing locally with what msmtp produces and observed it just puts in the characters as is, whereas if I try other client, like Emacs, that one will put in smtp utf8 string instead of the raw characters. With that, I am able to receive the mail properly in other clients.

I've solved this by copying =?utf-8?B?...=?= that was produced by other e-mail client using my full name. Should msmtp also support conversion to smtp utf8, or is it expected users will put this string in their configuration instead?

Hi, you are right, msmtp should properly encode non-ASCII content in the From header.

I will implement that as soon as I find the time. The solution will probably use base64 (?B?) instead of quoted-printable, same as in your example, since msmtp already has base64 code.

Confirming this works. Thanks.

The fix breaks Windows builds including msys2 as there is no langinfo.h and nl_langinfo(). There is PlibC implementation. I'm not sure if it is a good idea to pull it.

Should be fixed by this commit.
