Randomly, each and every day, we have periods where every machine in the office cannot connect to the email server and our email system stays dead for 5min or so. Web traffic seems completely unaffected.
Openhost have us on an old grandfathered POP3 only subscription but I have spoken with them a lot over the last few weeks and they swear black and blue it has nothing to do with them. We can switch to an IMAP subscription but we’ll have to delete all our current email addresses and re-do them on the new server, then copy the website over... but would that even fix the (potentially) underlying issue?
We have tried hot spotting a machine over wifi to a Vodafone mobile and the server stayed down. We then tried hot spotting the machine to my Spark mobile and it came back to life. Coincidence? The email issues persist for wifi and ethernet connected machines.
Using MXToolbox and checking the server typically returns only a warning that the server doesn’t support TLS. When we have email issues we also get warnings about the connection time being somewhere over 20 seconds and transaction time something similar.
Is it something DNS/Port related on the Vodafone side that we can fix simply enough? Or is it likely something else entirely?
I’d rather post here and get an idea of whether I should bother being stuck on hold for 45min with Vodafone, before I actually do it…
