214972 - Account Wizard rejects incoming server names containing an underscore

Status: RESOLVED DUPLICATE of bug 89945

(SeaMonkey :: MailNews: Account Configuration, defect)

Description

[Thomas Holaday]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5a) Gecko/20030718
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5a) Gecko/20030718

The name of my incoming mail server looks like this:  

aa.n1_n2.mail.isp.net

The Account Wizard rejects it, displaying an Alert box with the text "Please
enter a valid hostname."

It makes no difference if I say the server is POP or IMAP.

Reproducible: Always

Steps to Reproduce:
1. Click on Create New Account in Mozilla Mail.
2. Enter "John Smith" for your name and [e-mail] for the email address.
3. Click Next.
4. Select POP.
5. Enter aa.n1_n2.mail.isp.net for the name of the incoming server.  

Actual Results:  
An Alert box appears, with the text "Please enter a valid hostname."

If you change the incoming server name to aa.n1n2.mail.isp.net (removing the
underscore), it works.

Expected Results:  
It should have accepted aa.n1_n2.mail.isp.net as a valid hostname and proceeded.

The rejected hostname is (only) 21 characters long, so this does not appear to
be bug 68370.

Comment 2

Why should this block development ?

Comment 3

[Matthias Versen [:Matti]]

The warning is correct because "aa.n1_n2.mail.isp.net" IS no valid hostname.
a "_" is invalid

It absolutely prevented my testing.  The definition for "Blocking" status is
appeared to apply.  I regret the alarm.
