Email validating in c
That said, I would not recommend the use of Mime Kit for simply validating an email address (it's way overkill).
Instead, I have another (tiny) library that can be used for that which is written in accordance with the specification: Email Validation It's a fairly simple class that implements an actual email address tokenizer instead of using error-prone regexes that no one seems to ever get hello deepak, you cant check that ..because many browsers does not support this kind of functionality ..still you can give it try ..check this : I have been doing the same in my projet.
\^\`\~] @((((([a-z0-9][a-z0-9\-][a-z0-9])|[a-z])\.) [a-z])|(\d\.)\d(\:\d)? )$/i // Arluison Guillaume has also improved Warren Gaebel's regex.
] )*@([a-z0-9_][-a-z0-9_]*(\.[-a-z0-9_] )*\.(aero|arpa|biz|com|coop|edu|gov|info|int|mil|museum|name|net|org|pro|travel|mobi|[a-z][a-z])|([0-9]\.[0-9]\.[0-9]\.[0-9]))(:[0-9])?
Mail Address class to check if an exception occurs when creating the e-mail to determine if it is a valid or not : I suppose it depends on how you are currently sending it, but you might consider checking out this related Stack Overflow discussion along with this one which covers a few different techniques to try and check if your message was sent ().
Another important point to consider is that do you need to be performing this?
Just an FYI: I'm the author of Mime Kit which has already been mentioned on this thread.For example, entering A 25 character buffer for an email address?I'm not sure if I should cry because that's ridiculously short.If the user is going to be entering an e-mail address in, it should be his or her responsibility to ensure that it was entered in correctly ( You can try one of these free email validation techniques - to track bounced emails, you can build a console app using an open source POP3 library like Indy.
Sockets to download messages - You can then parse the messages to look for bounced emails using a free Mime parsing library like C# Mime Parser, Mime Kit or Sharp Mime Tools - Kit - that some of the components mentioned above haven't been updated in a while, so you'll have to try them out to verify if they work well.
Is it just to make sure that the user inputs something other than rubbish?
