Re: [Zope] Pseudo E-Mail Address validation
e-mail address exists or not, when you actually send a mail to the user, but a quick-n-dirty check would be nice. Maybe even complete RFC-compliancy as implemented in some Perl-Modules? (spaces, "@" sign, dot-notation etc.) There is a "monster" regular expression made by Tom Christiansen I think. A link is on http://www.perl.com/pub/doc/manual/html/pod/perlfaq9.html#How_do_I_check_a_valid_mail_addr The regular expression may be used in Python too I think.

Yes, I know this link - especially the absolutely voodoo-style regex by J.
Friedl ("Mastering Regular Expressions", O'Reilly). I tried to "pythonify"
the regex, but I failed. Python exits with some strange errors. Maybe
Python is not that exceptionally good in regex as Perl? *duck*
So I'm using the simpler method proposed by Dennis Nichols in this thread.
Thanks Dennis!

As a check on whether an email address *looks* OK, I use the following
External Method. If ICANN really approves TLDs that are other than 2 or 3
characters long then the {2,3} will have to be changed.
Warning: Some mail software between you and me may break up lines in the
code. There are two executable lines, one starts with "m =" and the very
next line starts with "return". There are no blanks in the r'...' string.
import re
def wellformedEmail(self, address):
""" return true if email address appears to be well formed """
m =
re.search(r'^[_a-z0-9-]+(\.[_a-z0-9-]+)*@([0-9a-z][0-9a-z-]*[0-9a-z]\.)+[a-z]{2,3}$',
address, re.IGNORECASE)
return m != None and m.group() == address
