Securing your account from prying eyes

We have always provided and encouraged the use of secure, encrypted communications to our servers but there have been recent events that have highlighted not only the importance of using encrypted links, but also ensuring that only trusted links are used.

As you may have read in various tech-press articles like this one configuring your email client to default to secure connections may not be enough to ensure the link was really secure since many clients when faced with blocked secure link silently fell back to insecure mode, allowing anyone in the path to read the id, password and email content.

We are pleased to announce that you can configure your account to ensure that even if your client falls back to insecure mode we will reject any connection attempt like an invalid account/password.

You can set these controls on your account by visiting the Email Security Controls page and setting the options to Yes.

You may also need to ensure your email client is set to use either “TLS” or “SSL” or “Encrypted” links and that it is connecting to the correct port.  Details of the preferred ports can be found here and configuration guides for various email clients can be found here

Please note that the third option on the page “Send from Authenticated Connections Only” is currently only of use for those remaining customers who are sending from permitted relay-ip address. This was the old mechanism for sending email where we simply trusted the IP address and is being phased out over the next few months.

 

Mail Quota increased for all Full Accounts

We are pleased to announce that we have increased the mail quota for all Full account users to 500MB.

Following our system upgrades last year and extensive testing of the further stability improvements we have been able to increase the available storage for all our Full Account users as part of the standard offering.

Your current usage can be found by enquiring of the Mail Folder Usage web page or it may be presented by your email client.  It can also be seen at the bottom of the folder list in the webmail client.

 

Upgrades complete

We successfully upgraded the main systems yesterday. All systems are now updated to level designed to give major stability for several years to come.

This completes our major operating system upgrade project and now lets us move forward in improving the features and quality of service we provide.

 

Downtime 2011-07-30 2011-07-31

We will be taking downtime on most machines on Saturday 2011-07-30 starting at 14:00 BST (13:00 UTC)

We will be working through the various machine upgrades sequentially, but ensuring that where possible there is always backup services at least for inbound email.

Depending on how these upgrades go we may delay some upgrades until Sunday afternoon.

Notice of Downtime – 2011-07-30 2011-07-31

We will be taking several hours downtime on each of our main hosting machines next weekend to perform major OS upgrades.

We will be able to give details of exactly when later this week after we coordinate with our hosters regarding access.

The plan is for each machine to be out for no more than a couple of hours. And we will sequence the updates in such a way that incoming email is always deliverable, even if final delivery for reading it is delayed.

These upgrades are the concluding steps in our ongoing upgrade of our various machines with the aim of providing a stable platform for our mail and blog services for at least the next five years.

New Tricks Live – Blocking more spam

We’ve just updated our spam recognition mechanism to include a variation on ‘grey-listing’.

As part of the content analysis we now check for common phrases present that would not typically be expected in normal email. If they are present and we’ve not seen them from the particular sender recently we temporarily reject the message. If the message is presented again after a short delay we will mark the email as spam allowing your particular rule (accept,reject,tag) to occur and delivery appropriately.  Since the vast majority of infected PCs acting as spam senders do not operate as proper email senders with industry accepted retry periods they do not send the same message again and so the spam no longer reaches your inbox.

Imminent Downtime

Due to the release of security related package updates we’ve decided to accelerate our updating of the master machines that host the virtual machines that run our services.

We are currently updating the machine that hosts the secondary access. The backup receiving machines and the primaries for the Beta service.  We hope to have the machine back up and running, along with all its virtual machines within a couple of hours.

On completion we will evaluate whether the remaining time available allows for the immediate upgrading of the primary services. We will post again once we have completed the first stage.

Disk problem

We’re having a disk problem on the main system, resulting in an
apparent heavy load. This results in 400-class errors reported
(451, etc) meaning “temporary error; please try again”.

As a temporary measure, reconfiguring your mail client to send
outbound via relay2.tidymail.co.uk will help. Unfortunately we
can’t do the same for accessing inbound mail.

More details when we have them.

We’re going for a reboot – but the disk is being recalcitrant.

We seem to be back.  Inbound mail has stacked up in the queue on our secondary server; it will be passed to the primary shortly.

Rejects search facility

We’re rolling out to Tidymail the facility for users to search for items for them which were rejected.  Most of these should be spam, but if you’ve been expecting a particular item which has not arrived, or if you just want to get a general flavour of the spam we’re rejecting on your behalf, the information is there.  It’s pretty raw, being just lines selected from our logs.

This is only a beta service; we might change it or withdraw it once we have some experience of how well (or not) it works.  One thing it will not show is rejects where we decided we didn’t like the sending system even before it got as far as telling us the item recipient.  It doesn’t handle aliases or catchalls either.

To use the service you must have your mail client configured to authenticate, so that we know what name to search the logs for.   Once that is set up, send a mail to rejectlog@tidymail.co.uk – the subject and content will be ignored and can be blank.  You should get sent a mail with selected lines from our logs.  The last couple of log files are searched, so there should be at least one full week’s coverage backward from the time of the request.

Each line should include a date & time, an IP address in square brackets (of the sending system) and a sender name in the form F=<user@domain> (NB: this is the envelope from, not the header from).  There should also be a reason for rejection.

We’ll be interested in your comments on this facility.   Mail to helpdesk@tidymail.co.uk

Downtime completed

Our scheduled reboot of machines has been completed without incident.

All dependent services are running correctly.

Please contact us at helpdesk@tidymail.co.uk should you notice any problems.
