Contacting POP3 server

[#1]

I have just joined PlusNet and have been trying to set up Claris Emailer 1.1v3 to send and collect e-mails.  Sending is working fine via the SMTP server, but I cannot get access to the POP3 server.  The mailbox and messages exist and are visible in Webmail .
C-Emailer uses an older form of setup, whereby the username and POP3 server address must be combined in one string; this is the same string which would be used to contact the server by Telnet.  Tech Support has agreed that the string which ought to work is :
[username]@mail.plus.net
OR
[username]@mail.plus.net:110
but neither Telnet nor C-Emailer can contact the server when using it.
What is the correct string?

Did you manage to sort this or are you still having problems?

[#3]

I'm still unable to contact the POP3 server either through Claris Emailer or by Telnet.

Found this information on Google. It's related to using a Mac and a specific service provider but hopefully helps.
That link suggests the POP3 entry should be username%mail.plus.net

I've tried 'username%mail.plus.net' but it times-out. 
Sometimes it needs the whole username before the "@domainname", which results in a string with two "@" signs; I have been told that when that happens, the "%" sign can be used to replace the first "@ "sign.  To see if that would work, I also tried "username%mail.plus.net@mail.plus.net' ; but that promptly came up with:
** Could not resolve the domain name “plus.mail.net” because no data
  was available for reading.

I know nothing about Claris, but doesn't the logic of what you say suggest you try "your-mailbox-name%username.plus.com@mail.plus.net" ?
Sorry if this is just daft, but if nothing else is working......

That looks far more promising.  It still fails, but with a message:
Connecting To Internet using Account “Plusnet broadband”
  Checking for mail
      ** -ERR Login failed.
So it looks as though it has found the server at last.
The next step its to Telnet it and see whether it baulks at the username or at the password.

Well I'm blowed!
Telnet needed the port number appended [mail.plus.net:110] then the following ensued:
(username and password removed)
~~~~~~~~~~~~~~~~~~~
+OK Hello there.
USER <username>
+OK Password required.
PASS <passwd>
+OK logged in.
stat
+OK 2 6416
list
+OK POP3 clients that break here, they violate STD53.
1 2632
2 3784
.
quit
~~~~~~~~~~~~~~~
Inspired by this (the first contact I have actually made to that server) I tired all sorts of combinations in Claris Emailer and found that the simplest of all:
<username>@mail.plus.net 
is now working.  I was beginning to think I had imagined the problem, but neither I nor Tech Support could get it to work last week, so I suppose something has altered since then.
Two e-mails successfully downloaded.

{Afterthought]  When I first registered on Plusnet, there was a spelling mistake in my username which was subsequently corrected.  I wonder if the error also found its way into the mail server and has only just been discovered and put right?

Glad this now seems to be working for you. Welcome to Plusnet!
