How to Send E-mail to a Winlink User

To send a message to a Winlink user (or, to allow the user to receive it) the sender's e-mail address must be listed in the recipient's whitelist (accept list). If the sender's address is not there the message will be rejected. This restriction can be bypassed by including a special keyword in the subject line of each message. For example:

Subject: //WL2K (then any normal subject)

The "//WL2K" informs the Winlink mail processing system to allow the message to be forwarded to the Winlink user. This code may be changed from time-to-time.

Why are you doing this?
SPAM control on the WL2K system is important because our licensed users and station operators are bound by laws and regulations that prohibit the content of most SPAM over radio. Moreover, slow radio circuits are easily clogged with unwanted messages when an urgent or emergency message must get through.

I need a better explanation of why I'm not getting through...
Your rejected message came from an e-mail account with an address that this WL2K user has not included on their "accept list". Normally, if you have first received a message from a WL2K user, the address it was sent to was automatically placed on their "accept list". Sometimes however, your e-mail account may be set such that your reply address is different than the address from which you send, or perhaps your internet mail provider is using an unusual method of mail header addressing. This can result in your reply being rejected, because to our filter your mail appears to be coming from a different address or domain than the e-mail address where you received messages from our user.

Thanks for your understanding.
