I am having an ongoing issue where emails, seemingly at random, will say they come from one email address in the from column but, upon opening it, the email body says it is "From: " a different address.

The emails and the addresses are confidential so I cannot show a screenshot of the issue.

However, the email account was originally setup as POP, and had an issue where random emails would display as random strings of characters. Changing the text encoding (Western to Unicode etc.) did not produce results. Switching to IMAP resolved this issue.

In both the POP and IMAP account the FROM Column can appear as different to the FROM in the email.

I have confirmed that these emails are not being forwarded.

I have checked in the web portal (powered by GMail) and the issue does not display there.

Can somebody please advise on steps to take to resolve this?

Background: I am running no addons in Thunderbird. I have configured the email address in question on POP and IMAP on 2 separate accounts. The issue still persists.

It sounds like your mail files are corrupted. First of all create a backup of your Thunderbird profile folder. https://support.mozilla.org/kb/profiles-tb#w_backing-up-a-profile

Then try to rebuild the index file of the troubled folder. Right-click the folder - Properties - Repair Folder

Note: depending on the corruption this may erase messages from the affected folder which cannot be recovered anymore. In that case you'd need to restore them from a recent backup done prior to the corruption.

Corruption is often caused by anti-virus software messing with Thunderbird mail files. It is therefore recommended to create an exception for the Thunderbird profile folder, so that the real-time scanner won't attempt to scan the profile with your mail.

For more information on the profile location see http://kb.mozillazine.org/Profile_folder_-_Thunderbird
