JavaMail

[cajchris]

I am writing some functionality for a site which deals with newsletters, and the sending of them to their subscribers. When an email is successfully sent the subscriber entry in a file is checked as sent, however if one is not sent, how can i determine between different error codes for smpt. such as the server being down, incorrect email address of any other error for that matter, as i will need to flag these subscibers accordingly.

thanks

This all depends on which MTA you are using - JavaMail is not an MTA in itself.

For example, if you know that joe@bloggs.com 's MX server is smtpin.bloggs.com for example, then if you send a mail directly, and there is an error, then you will see that error - however if you are not sending to the recipients own MX server, then (as is usual) you are using some other MTA, you will not be able to retrieve error codes.

You need to say more about how you are using JavaMail.

what is an MTA, and MX?

 

[sedj]

MTA = Mail Transfer Agent
MX = Mail eXchanger (as in MX records for domain names)
