No, it is not.
However, I just looked at the IMAP4rev1 standard and noticed that the
APPEND command does allow the internal date to be specified when a
message is uploaded. Sure enough, Mutt does provide this information
(see mutt/imap/message.c, line 639). IMAP4rev1 has this to say:
If a date-time is specified, the internal date SHOULD be set in
the resulting message; otherwise, the internal date of the
resulting message is set to the current date and time by default.
Notice that it does not say MUST. So I'm wondering if OP's IMAP server does
not honor the given internal date. I suggest using debug mode (mutt -d 5)
in order to see what Mutt is passing to the server in this case.
