I did not thought of this. If the rfc library can work with this, it will
not be a big issue since I never access the file directly. Only the content
of the message may be with wrong lines ending ?

I'll give it a try tonight. In the mean time I got the quick and dirty
solution of:
1) test for end of file
2) make a backup of the file
3) replace all '\r\n' by '\n'
4) write this to the file
5) close the file
6) reopen it in 'r' mode.

Somewhat ugly.
