Status: RESOLVED DUPLICATE of bug 226303

(Thunderbird :: Account Manager, defect)

Description

[Bartolomeo Trombetta]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.5) Gecko/2008121622 Ubuntu/8.10 (intrepid) Firefox/3.0.5

If there's a server that acts like a nat, happens that it shows different internal servers on the same IP (and the same name).

When you have POP3 server (let's call it serverA) reachable with name mail.anydomain.com on port 3500 and another POP3 server (let's call it serverB) reachable with the same name, but another port and on both you have the same username (let's say admin) you cannot create two profiles that points to

POP3 - [e-mail]:3500
and
POP3 - [e-mail]:3501

because TB only check that protocol, username and hostname are the same without looking at the port.

It should use the tuple protocol, username, hostname and port because it's legal that a server shows different machines on different ports on the same IP address.

Not tried with IMAP.

I think this is a platform-independent bug

Reproducible: Always

Steps to Reproduce:
1. Define a new mail account on a server defining protocol, username, hostname and port
2. Try to define a new mail account with the same protocol, username and hostname, but with a different port

Actual Results:  
At step number 2 you get a message box that says:

"An account with that username and server name already exists. Please enter a different username and/or server name"

Expected Results:  
If the new account points to a different TCP port, it should be created normally

The only workaround I find is to specify an alias for the second (or any additional account) to make it appear a different host, but this is not always possible.
