Bad emails

[#1]

A few weeks ago I received an email from a friend. It looked a bit odd, so I replied asking for clarification. It turned oiut her email account had been hacked and my reply sucked me into the problem. Since then I've been getting emails making faise claims against me. I use Mailwasher so could see those emails before they got to my pc, and deleted them there. Eventually I blacklisted that address. Now I'm getting them apparently coming from my own email address, and quoting my Plusnet password. 

I've used Malwarebytes Free, Spybot, and Microsoft Security Essentials but nothing spotted except Spybot stated Error During Check - Win32.OnLineGames.gen, but it didn't do anthing about it.

Any suggestions as to how I deal with this?

Many thanks for any help. I've unticked the box so your replies dont get emailed to me in case he/she can see them

Change your Plusnet password and, heaven forbid, any other accounts if you have ever reused passwords.

Not many can be bothered but if I find any of my email addresses listed as leaked on the haveibeenpwned website, I scrap that address.

Thanks @Baldrick1 . I have just gone onto Plusnet to do as you suggest, and it seems I changed my password a long time ago, so it must have been years since I used the password that person was quoting - it was so long ago I had forgotten I had done it. Therefore I'm not using that password any more anyway.

So the questions are:-

How is he/she sending me emails which shows my email address as the source?

How can I stop that happening?

Could he be deliberately quoting a wrong password to stop me changing my password?

Can he see my email address book, so he can get other people to bother?

Regards and thanks

"How is he/she sending me emails which shows my email address as the source?"

Plusnet have configured SMTP server relay.plus.net as an Open Relay, making possible to send emails as you describe without being a Plusnet internet customer and without needing a Username or Password.

Is there a way I can identify his emails, no matter what source email address so I can blacklist them, without adversely affecting my emails? That way, if he changes to yet another source address, his emails to me are automatically blacklisted

Cheers and thankyou

Be careful not to accidentaly block yourself ! Block on unique concurrent words in the subject field.

Not sure if Mailweeper has this facility, @jab1 may be able to help. If not use your client software..........

[#7]

AFAIK, MW does not have that facility, and I unfortunately can't check - a recent OS update means I can't open that program - they forgot, or decided not to include the relevant folder in the revised coding. My version of MW is based on 32-bit architecture, and the i386 folder is no longer there.

Thanks @jab1  A quick install of Ver 7.15 shows under 'Spam Tools -> Filters' there is an option to set up rules including  'subject contains'

[#9]

OK, @Champnet . Unfortunately, that version, or at least the fully-featured 'Professional' one I need for multiple mailboxes is subscription-only - and as I am moving away from Plusnet/Greenby I am loath to pay for something I am not likely to need in the next 2-3 months. MW themselves have said that 6.5.2 is the last one that will work on Linux systems.

[#10]

A quick install of Ver 7.15.45_Pro_Free shows under 'Spam Tools -> Filters' there is an option to set up rules including  'subject contains'

[#11]

Is this on Windows or Linux? As I said, Mailwasher support did say 6.5.2 was the last version compatible with Linux, and I haven't checked any later versions.

[#12]

Has your email been transferred to Greenby yet ?

If so most of the complaints are of Greenby putting legitimate emails into 'spam' and therefore not delivering - rather than spam getting through that should not.

Running in a Win 10 LTSE setup in a Virtual Machine on a Synology Server…

Reckon we’ve discussed my lack of interest in Linux or Unix  before.

Fair enough - I have no interest in Windows, either.😀
