I am sorry to say this, but Afrihost does not have a good track record when it comes to mail or hosting. In 2012 for example Afrihost used SpamExperts.com to identify spam and then applied a spam-filter which only did a partial match of the DKIM header (for whatever reason they decided not to match the full 240 bytes public key DKIM header but only the first 16 bytes and the last 6 bytes) - as you can imagine, only matching a portion of a public key resulted in a number of legitimate senders (we were unfortunately one of those) being blocked and marked as a "botnet" (@Afrigenie - this was ticket ASH-990-5796 from June 2012 and Bruce VR/your support team was incapable of helping there).
I would have a lot more consideration for such mistakes if I did not have dozens of similar mistakes (such as the time when your network staff introduced a switching loop into the DiData network causing a broadcast storm and then blamed IS for their poor infrastructure). Mistakes can happen, but to me it appears that lack of knowledge and attention to detail or following basic operational principles when running a hosting environment are to blame for most of the issues.
Disappointingly none of those issues are followed with transparent disclosure and are always buried to avoid getting bad press.
This gives much needed depth to the exact reasons why I moved all my hosting away from AH over a year ago
Why anyone would still want to be dealing with a deceptive company like this is beyond me.
