We have had an ongoing problem with email messages sent to fnbzambia.co.zm over the last few weeks. This is despite our best efforts and the fact that 99% of the rest of our email is handled smoothly.
After asking an FNB client to liaise with FNB over the problem (because they don’t have a working “postmaster” address), we received an email through them from FNB showing that they don’t know how the Internet works. They went to the trouble of telling them that their web server was in multiple blacklist, despite the fact that we obviously send our email through a mail server.
We also found out that the company through which we send some of our mail had some DNS problems a few weeks ago, which explains why some email to fnbzambia.co.zm was bounced.
So we have removed the block that we had instituted on emails to some fnbzambia.co.zm addresses under the assumption that they will now get through. This included an email address to which clients had to send invoices to prove something or another that has to be proved.
Hopefully the problem has now been resolved.
