[vchkpw] vpalias.c PATCH for .qmail-name.name or .qmail-name:name

[Erin Quinlan]

Hi all..

I found a bug in valias.

# valias -i "&[EMAIL PROTECTED]" [EMAIL PROTECTED]
# valias [EMAIL PROTECTED]
[EMAIL PROTECTED] -> &[EMAIL PROTECTED]

# valias -i "&[EMAIL PROTECTED]" [EMAIL PROTECTED]
# valias [EMAIL PROTECTED]
# valias erin:[EMAIL PROTECTED]
user invalid erin:quinlan
Error: Illegal username

The attached patch fixes it for vpopmail 5.2.2

# valias [EMAIL PROTECTED]
[EMAIL PROTECTED] -> &[EMAIL PROTECTED]
