[qmailadmin-devel] qmailadmin versus Email::Valid. What's a valid e-amail address ?

[Mark S. <ma...@su...>]

Hello,

The following patterns were flagged by the 'Email::Valid' perl module as
invalid e-mail address formats.. This solution uses a particularly long
and hairy regular expression that's supposed to match the details set
forth by the RFC 822 spec for e-mail addresses. 

Here are the three cases:

 .lea...@te...
 two..do...@te...
 DotBeforeAt.@test.com

The current QmailAdmin demo accepts all of these as "valid" addresses.

On my own server, running QmailAdmin 1.2.10, I was able to successfully
send mail to two out of the three addresses. The leading dot failed to let the
mail through to one of the formats:

 .lea...@te...

That seems like a bug in QmailAdmin: If I can create the address, I
should be able to send mail through it. If the address format is not
valid, I shouldn't be able to create it.

What are opinions of the experts here: Which if any of these
patterns should be treated as valid e-mail addresses? 

The all look like mistakes, but my testing with QmailAdmin revealed
that two of these formats actually can work "in the world" regardless
of the RFC.
