Comment:
I'm not convinced this should be closed. Although DNS should correctly
resolve a domain with a trailing dot according to the specification
(documented at the beginning of page 7 here
http://www.ietf.org/rfc/rfc1034.txt) sending emails to addresses that end
with a dot fails at least in my case. For example I tried sending an
email to and from a google apps address of mine using thunderbird. I was
sent back a Delivery Status Notification (Failure).
When trying to use EmailMultiAlternatives with a email address of this
form, m...@domain.com. as an example, msg.send() breaks with the following
error:
SMTPRecipientsRefused: {'m...@domain.com.': (501, '<tedlitt...@aol.com.>:
domain missing or malformed')}
Here is a quote from RFC 5321 section 2.3.5
(http://tools.ietf.org/html/rfc5321#section-2.3.5):
"A domain name (or often just a "domain") consists of one or more
components, separated by dots if more than one appears."
I think the important word is separated, it does not say terminated
therefore an email address should not be terminated by a dot.
More discussion on that here: http://tech.groups.yahoo.com/group/postfix-
users/message/244166.
At the very least I think this needs to be revisited and properly
discussed. Emails with dots at the end do not send so why should they be
validated by Django?
