I had "set dsn_return = hdrs" in my muttrc. Once I commented it, NeoMutt was
back to defaults and I was able to send (just like I am able to send this
message sending NeoMutt).

$ grep dsn_return .mutt/*
.mutt/muttrc.conf:# set dsn_return = hdrs

Since I can send now, I assume having "set dsn_return = hdrs" ended up in
rc=hdrs and not RET=hdrs during SMTP session. At the moment this looks like a
problem in NeoMutt to me.

Yes, it does:

$ telnet mail.sys4.de 587
220 mail.sys4.de ESMTP Submission
EHLO p.sys4.de
250-mail.sys4.de
250-PIPELINING
250-SIZE 40960000
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-DSN
250 SMTPUTF8
QUIT
221 2.0.0 Bye
