For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Our email filters
We receive thousands of unsolicited emails every day and most of them include a virus, or are sent out to thousands of people at the same time and are advertising products in which we have no interest at all. In order to keep our business running efficiently, we need to filter out these emails automatically and we use "spamassassin" to identify them.

Unfortunately, occasional emails look like they're spam but are genuine, so our spam filter sends an automated message in response to anything it blocks. If it's a true spam message that's been blocked, our message will be ignored anyway and if it's a genuine message blocked in error, then our correspondent is alterted and told what to do. Here's the current version of the message:
Automated response ================== Sorry - your email to someone at one of the following domains: wellho.net chs73.info wellho.co.uk wellho.com has NOT been delivered. We receive a large quantity of bulk, unsolicited email at these domains. Our mailwatch routine blocks final delivery of email which appears to fall into this category. HOWEVER ... since you're reading this message, the email it has just blocked probably WAS genuine. PLEASE write to us again - we don't want to miss your message! If you add "Melksham", "Carlisle" or "edu-k" onto the subject line, mailwatch will let it though irrespective of the rest of the email.

With unsolicited mailers getting more and more clever, it's something of a battle to keep ourselves well filtered and this is especially the case as we have to have unchanging, public addresses. Here's a further explanation (names have been changed) if you've received an automatic response from us and and looking for more information:
John, Many thanks for alerting me to your puzzlement. We wrote when WE received two emails that said they were from YOU!! They arrived at 18:56 (GMT) yesterday, were addressed to mail@wellho.net, were 70k long each, said they were from johnsomeone@hotmail.com, and had the subject "why do you do that". Our email addresses are well known and we receive a large number of viruses and a great deal of unwanted advertising by email, and very often such emails claim to come from some innocent party, which is probably what has happened in this case. Our automated mail filters can recognise most such emails, but they can't be 100% sure so in doubtful cases they send back the email you received to alert you to the fact that an email, apparently from you, was blocked - and also to tell you how you can really reach us. Our action is pretty standard practise, and your email is the first letter of "complaint" I have received in over a year. We really can't turn the system off, but I can assure you it will only write to you again if we receive a further email that looks like a virus or spam and claims to come from you. Please accept my apologies for the need for us to defend ourselves in this way and have troubled you with two copies of an alert email. Any suggestion as to how we might improve the wording of our automated response would be gratefully received - it does seem it wasn't clear to you. And if you happen to be passing by our training centre (I don't know what part of the world you're in!), do drop in for a coffee.
