MSGTAG Info Being Stripped by Ironport Servers

I have now discovered that my MSGTAG message receipt verification program (see www.msgtag.com) no longer works for any recipient with a plus.com email address who has had their email account migrated to Ironport (that is most Plusnet email addresses at the time of writing).
I have a friend who also has a Plusnet email account and uses Mozilla Thunderbird 2 for their Pop email and who has me in their address book (so that the MSGTAG HTML info is not blocked by Thunderbird) but since the switch of their email account to Ironport I am not getting MSGTAG read messages when emails are opened by them.  I then tested this by sending a message back to my own Plusnet accounts and found that it arrived as a text only message without any of the HTML info or images added by MSGTAG to verify a message has been opened.
Can someone at Plusnet confirm if the Ironports are currently set so that all incoming HTML mail is converted in to plain text only format and if so can this be changed so that we can please receive messages sent in HTML format as HTML.  Whilst I realise that some of the most paranoid corporate email setups convert all emails to plain text for security reasons there are many disadvantages to doing so and this is hardly likely to go down well with the customers of a basically retail focused email service.  I do realise of course that HTML content in messages can be used to contain viruses and Trojans but I thought that was what the Ironport Spam filtering option was for.  We shouldn't have HTML content also blocked from legitimate senders.
I realise that MSGTAG does not work with email programs that block HTML content by default or where the user has chosen to block it but it is very annoying that when someone is still using precisely the same email setup as before and MSGTAG was previously working on their PC that it is now being prevented from working by the current settings on the Ironports for stripping HTMLcontent in incoming emails.  I am sure these settings could be changed so that MSGTAG would still work.
If this is not changed this may mean I now have to investigate an alternative product like www.readnotify.com which uses slightly different technology so may perhaps not be blocked by the Ironport servers?
As I can't be the only MSGTAG user who is also a Plusnet email customer can someone at Plusnet please comment on this.

I'm getting HTML messages. If messages were being converted I'd have expected an absolute storm about it some days ago!

Well MSGTAG's embedded HTML hooks and images definitely are being stripped out by the Ironport servers, perhaps because Ironport's and/or Plusnet's or BT's directors (note that the senior management of Plusnet is now directly ex BT) don't like their customers tracking when they have read emails that they have not yet got round to answering.
By the way my outgoing email is sent with www.adsl24.co.uk and their SMTP server so nothing has changed on that score to prevent MSGTAG from working.  I am also still getting MSGTAG read receipts from people I was previously getting them from who do not have a Plusnet email account.

Quick, grab a tinfoil hat.
I have to say I've just installed MSGTAG and sent a test email from my PN account to my PN account and the nasty horrible web bug they use to illicitly track the email was still there (although pleasantly blocked by Thunderbird)

Re: MSGTAG Info Being Stripped by Ironport Servers

Well it definitely wasn't there in the message I sent to myself.
It sounds to me like some of Plusnet's Ironport servers are stripping HTML without permission while some of them are not.

That's a ludicrous assumption and isn't true at all. Looks like whatever your problem is it isn't a service wide because it seems like Barry's been unable to replicate the issue. I'm (reluctantly) downloading MSGTAG now so I can play around with it a bit. BTW, what version are you using?
Would probably help if I knew more about the scenarios in which this is not working to. What mail client are you sending messages from, what mail client are you sending messages to, what outbound mail server are you using and are the messages being sent to a .plus.com address or a domain that's hosted with us?

By the way my outgoing email is sent with www.adsl24.co.uk and their SMTP server so nothing has changed on that score to prevent MSGTAG from working.

Just noticed this. What happens if you change this to relay.plus.net, or are you not connected on a Plusnet line?

Re: MSGTAG Info Being Stripped by Ironport Servers

Hi Bob,
Regarding MSGTAG it seems that the hand of coincidence can do some very strange things indeed in life.
For reasons I do now begin to dimly recall and that had to do with a Yahoo group that I rarely post in that would not accept inbound emails in HTML format it seems I turned off HTML formating on outbound messages in Mozilla Thunderbird 3 but unbeknown to me this also turned off presentation of HTML formatting in my Inbox messages in Thunderbird, instead showing them only in plain text.  This became rather more obvious to me yesterday afternoon when a weekly email from Ticketmaster that was totally in HTML format was completely invisible. Embarrassed Embarrassed Embarrassed
At the same time for some reason or other I also didn't get MSGTAG receipts back for two emails I sent to somebody I regularly deal with who I always get MSGTAG receipts from a couple of days ago, even though I know they read them because they responded to my email.  It would now appear something has changed at their end.
So sorry for jumping to the wrong conclusions.  Now where are those birch twigs and that sack cloth and those ashes? Shocked Embarrassed Embarrassed Embarrassed
