email-address

I have a comma-delimited list of email addresses with each actual address prepended by the contact's name (from Gmail). Here's an example: Fred Flintstone <fred@flintstone.org>, Wilma Flintstone <wilma@flintstone.org>, Barney Rubble <barney@rubble.org>, Bamm-Bamm Rubble <bammbamm@rubble.org>, converts to: fred@flintstone.org, wilma@flintstone.org, barney@rubble.org, bammbamm@rubble.org, Background info: I am trying to paste the list of contacts into a webex invite, which can only accept email addresses. Remove everything except regex match in Vim is related, but all the email addresses are on

Can anyone help me with a regular expression that will return the end part of an email address, after the @ symbol? I'm new to regex, but want to learn how to use it rather than writing inefficient .Net string functions! E.g. for an input of "test@example.com" I need an output of "example.com". Cheers! Tim A regular expression is quite heavy machinery for this purpose. Just split the string containing the email address at the @ character, and take the second half. (An email address is guaranteed to contain only one @ character.) @(.*)$ This will match with the @, then capture everything up

My dad says capitals used to matter (years ago) for email addresses but don't anymore. I'm fairly sure they never did because something like that involving DNS/MX changes would not change. Especially with no easy to find record online. Let's look at this in pieces: The domain part of the email address needs to conform to RFC 1034 and is thus (and has always been) case insensitive: http://www.ietf.org/rfc/rfc1034.txt The local part of the email address is handled by the receiving mail server and thus whether or not it is treated case-sensitively in theory depends on that server. Some mail

Many users and forum programs in attempt to make automatic e-mail address harversting harder conseal them via obfuscation - @ is replaced with "at" and . is replaced with "dot", so team@stackoverflow.com now becomes team at stackoverflow dot com I'm not an expert in regular expressions and I'm really curious - does such obfuscation really make automatic harvesting harder? Is it really much harder to automatically identify such obfuscated addresses? Definitely! I read this article a while ago which shows how effective (as well as the relative degree) the various methods can be. Reversing an

Currently, to avoid errors from being thrown up due to invalid email addresses, I do the following: Dim mailAddress As MailAddress Try mailAddress = New MailAddress("testing@invalid@email.com") Catch ex As Exception 'Invalid email End Try However, rather than depending on Try..Catch , is there a way of validating that the email address will be 100% valid for the MailAddress type? I know there a plenty of regex functions out there for validating emails, but I'm looking for the function which the MailAddress type uses to validate its addresses. Unfortunately, there is no MailAddress.TryParse

Does anyone know a regex that validates email addresses according to RFC5321 / RFC5322 ? Since (nestable) comments make the grammar irregular, only addresses without comments should be regarded. Of course, if you're interested in validating an address that is actually owned by someone then the only real validation is to send an email to the address and check if the owner received it. I am however purely interested in the RFC standards. For a practical approach this question is more relevant. On top of comments I am willing to sacrifice folding white space, but apart from that I'm not

Are german umlauts (ä, ö, ü) and the sz-character (ß) valid in the local part of an email-address? For example take this email-address: björn.nußbaum@trouble.org RFC 5322 quite clearly says, that umlauts (and other international characters) aren't allowed. If I take a look at chapter 3.4.1 , there's the following regarding the local part: local-part = dot-atom / quoted-string / obs-local-part So what means dot-atom ? It's described in chapter 3.2.3 : Well, long story short: Printable US-ASCII characters not including specials So in the whole RFC 5322 I can't see anything regarding
