Avoiding errors due to bad email addressesI am making an application that will be used to send an email message to all
members in a certain group (such as maybe all exec board, or all IT, or all secretaries, etc.). However, as we all know the may occasionally be a misspelled email or, more often, someone's email is not working, or for whatever reason an address returns the message. I want to avoid having this error displayed, but I still need to know which addresses it did not get sent to. How can I do this? The ideal solution would be a method that tests whether an address is valid, but I don't know of one. Thanks. Dear Nathan Sokalski,
Please have a look at Regex (look it up in your docs) and take a look at http://www.regexlib.com/ (or any other regex website). Regex is short for 'regular expression' and is a way to test strings to be in a specific format (eg an emailaddress or postalcode). If you regex succeeds then your string is in a valid emailaddress format. About the email address returning the message: there are some third-party controls/websites that do this for you. For example: http://www.glocksoft.com/amlv/index.htm However, I don't know how good these are, but I do know that implementing it by yourself is a lot more work! If you would like to do it by yourself then you should look into the SMTP. Hope I helped you, Michel van den Berg Show quote "Nathan Sokalski" <njsokal***@hotmail.com> schreef in bericht news:OnC%23lOu6FHA.3340@TK2MSFTNGP10.phx.gbl... >I am making an application that will be used to send an email message to >all members in a certain group (such as maybe all exec board, or all IT, or >all secretaries, etc.).
