Emails going directly to Trash, unread on iMac

[Hysteresis]

I use an iMac with OS Yosomite, old OS I know but i don't want to upgrade unless absolutely necessary.
I encountered a problem when a friend asked if I had received his email. Initially I said I hadn't as I had no mail notification in my inbox. He tried several times to resend the mail and still I had no notification of receipt.
I eventually found all of his sent mails unread in my Trash file. All other senders appear correctly in the inbox so the problem is related to only one sender who happen to be using Talktalk.
I can't find any setting or filters which could cause this to happen. Searches on the internet for a solution revealed that a number of people have had this issue, but none of the responders to the problem came up with any practical solution. Suggestions were filters and settings none of which were useful. Another suggestion was to view the Mail in trash and mark it as 'not junk'. There is no such facility and anyway the mail was not in the Junk box, it was in the Trash box.
This has only just started to happen and means every time I open my mails, I have to took in the trash box to see if I have any mails unread in there before I look at the inbox. Clearly I do not receive any indication on the mail icon that tells me I have unread mails in my inbox.
Can anyone give me help in the resolution to this issue.

I'm not a Mac guy, but Mail> Preferences> Rules show anything?

Are you using "mail"?
I use macs but the entire organisation is on windows apart from some specialists, so changed to office 365

Is he in your address book?

Which is the primary holding location for your eMails?
On the Mac or on the eMail providers Servers?
Once we know that we can advise further.

Thanks Chalkywhite, Preferences seems to refer mainly to Junk mail filtering, I can't find any settings relating to Trash, other than when searching mailboxes I include results from Trash.

Thanks Tigercubrider, The sender is in my contacts . I have had the sender send another test mail to confirm it is still happening and indeed it is, his mails are going directly to my trash box as unread. I can't understand why this should happen only to his mails which is via Talktalk. If I had any filtering conditions set incorrectly, I Presume the rules would apply to all other senders but it only happens to one sender so far. This all suggests to me that there is an issue with Talktalk/Gmail interface. It has only just started to happen, it was all OK on previous mails.

Nothing under "rules" rather than referring to trash. My guess is that a rule is there to move msg to trash on receipt.

Hi Chalkywhite. Cant find any rules relating to messages to trash, and it is only occurring from one message sender using Talktalk, DO you think it may be a Talktalk problem?
It all starts to get a bit complicated from mr limited understanding on these issues.
At the moment I have Gmail set up as a client to Apple Mail. DO you think this is a problem?

Hi wgt52,
I think my primary holding location for my emails in on my Mac.
As I said to Chalkywhite, I have my Gmail as a client to Apple mail. In that respect I think my mails holding location is my Mac, but in my ignorance I thought the mails were held on Gmail also. Does that make sense?

From the Gmail help pages - Asking about emails going directly to the Trash box -

If your incoming or sent messages are automatically placed in Trash, the cause is a misconfigured filter, or a setting on your Forwarding and POP/IMAP tab. To resolve this issue, please make sure you haven't created any filters with the action Delete it that would affect the messages in question. If you have many filters or have complicated filters in place, you may need to edit the Delete it action to guarantee that they are not at fault. ( clickhttps://support.google.com/mail/answer/6579?vid=0-883670138179-1512121942364 ) ( if there are filters listed those are active filters. If the boxes are NOT ticked, that doesn't mean the filter is inactive ) If you've enabled forwarding in your settings, please ensure that you have not selected delete Gmail's copy in your forwarding options. If you're using a POP client to access Gmail, please ensure that you have not selected delete Gmail's copy in step 2 of your POP download options.Finally, if you're accessing your Gmail from multiple POP clients (with recent mode), please verify that you have selected 'Leave a copy of messages on server' in your client configuration settings.

You probably have set a filter on Gmail against either the persons identity or against 'TalkTalk' globally. Open Gmail (not your mail client on the iMac) and undertake 'gearwheel' look for filters.

Filters are found by opening a problem eMail (in Webmail >Gmail.com/your account<, header line, R/H side, the 3 dots; under that is a comment about filters) and un-checking that (I think).

Hi W,
Thanks so much, the link to the Gmail Help Pages identified the problem.
There I found a filter for Talktalk mails. Just how that filter became set I will never know. I was not aware of the Gmail help page and quite how Gmail operates as a client to Apple mail. I have learned a lot from your advice, thanks again.
Problem solved.
Thanks again

Glad to have been of help. I know problems in this area (eMail & Webmail) can be very difficult to sort if you are not sure where to look.
