Since last update of MBM, my ISP (Free, a French ISP with about 3 millions customers) seems to block receipts for messages sent through this software— and this is so even when I use their own SMTP. There is no error message, just that recipients do not get what I sent. Other ISP let MBM mail through.
Could it be that this is a header problem?
What can I do to trace the problem more accurately?
Previously everything went through smoothly. Where can I find an older version of MBM to check whether the problem does come from the new version?
