919614 - Thunderbird ESR picks up mail for fiona@mfcomputing several times.

Status: RESOLVED WORKSFORME

(Thunderbird :: Untriaged, defect)

Description

[fiona]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0 (Beta/Release)
Build ID: 20130911042038

Steps to reproduce:

ESR 17.09. I have an email address [e-mail] (among four other addresses). Each time I Get Mail from this account, TB picks up the new mail, and also two or three or four emails that I have already received and are already in the Inbox. If I Get Mail again a minute later, it will pick up the same or other old emails.
TB works fine with the other four email addresses.


Actual results:

The Account Settings are:
Check for new messages at startup,
Check for new messages every 14 minutes,
Check automatically download new messages,
Check leave messages on server, for 14 days, until I delete them.
Advanced: Include this server when getting new mail.
Connection  security is none,
Authentication method: password transmitted insecurely.


Expected results:

I should receive each message only once. My other accounts work correctly including another @mfcomputing.com address.

A few days ago, I got this message several times:
"The POP3 mail server (mail.mfcomputing.com) does not support UIDL or XTND XLST, which are required to implement the ``Leave on Server'', ``Maximum Message Size'' or ``Fetch Headers Only'' options. To download your mail, turn off these options in the Server Settings for your mail server in the Account Settings window."
I don't get it any more

All is well now. I was having several other minor problems with my computer so went back a couple of weeks with Macrium Reflect and then came back up to the present.

I suspect my problem was a PUP that I carelessly allowed in. They're all over these days.
