| <h2>SMTP Hooks<a name="SMTP_Hooks"></a></h2> |
| |
| |
| <p>The James SMTP Server Component allows to easy write your own code which will get executed |
| in the SMTP-Transaction. Thats a bit different then using a Mailet a.k.a Mailet-API.</p> |
| |
| |
| <p>To customize your SMTP Server, you have a few interfaces which helps you to "hook-in" a |
| specific SMTP Command. That means your class which implements the given interface(s) will get |
| called after the SMTP-Command was parsed and depending on your implementation it will handle it.</p> |
| |
| |
| <p>As your code will get executed before the mail was even accepted. This can help you in many ways, |
| most times its used for rejecting SPAM/Junk within the SMTP-Dialog. But it can be used for |
| other things too.</p> |
| |
| |
| <p>Its up to you and your use case.</p> |
| |
| |
| <p>But be aware as your code needs to get executed during the SMTP-Transaction it should not |
| take to long to execute. As it will need to fit in before the timeout was hit which can be |
| different on every mail server. But as a general rule as long as your code can get executed |
| within 30 seconds it should be fine.</p> |
