How to Send Email to a Winlink Address

If you had a message rejected...

You may have received a rejection message "554--Profanity not allowed."
This is because your message contained language or words considered indecent or profane and is not permitted in communications transported by amateur radio stations. If you submit the same message without offensive language it will not be rejected. In the USA, please see FCC rule Part 97.113(a)(4). Other licensing authorities have similar rules.

Your message was rejected because it came from an e-mail account bearing a reply address that is missing from the "accept list" of your recipient WL2K user. Normally, if you have first received a message from a WL2K user's account, the address to which they sent your mail will have been automatically placed on their whitelist (accept list). Sometimes however, your e-mail account may be set so that your reply address is different than the account address from which you send, or perhaps your internet mail provider is using an unusual method of mail header addressing. Or, your recipient may have purposely blocked mail from your address or domain. In these cases, your message will be rejected, because to our anti-spam filter your mail appears to be coming from a different address or domain than the e-mail address where you receive messages. This is the way spam gets sent. Your mail set up makes your messages looks just like unwanted spam! Use the method above to bypass the spam filter if these cases apply to you.

How to Send a Message From an Internet Email Account to a Winlink Account

For a Winlink user to receive a message, the sender's e-mail address must be listed in the recipient's whitelist (accept list). All Winlink accounts have this feature to purposely block mail from the internet that is not expected or permitted. This filter can be bypassed--and the mail will be delivered even if the sender is NOT on the recipient's whitelist--by including a special keyword in the subject line of the message (explained below).

Message Precedence and SPAM Control
Precedence indicators control the order in which messages get processed and sent across slow radio links through the Winlink system. It also includes a mechanism to block SPAM--unwanted and unexpected mail--from the system. Precedence categories are Flash (Z), Immediate (O), Priority (P), and Routine (R). Flash and Immediate messages are reserved for highly urgent messages. Unless there is some special circumstance or urgency routing precedence //WL2K R/ should always be used. "R" is the default if omitted.

The precedence indicator is included in a Winlink message by adding one of the following to the subject line--whether originated from Internet email or from a Winlink address.

//WL2K Z/ - Flash (for urgent message use only)
//WL2K O/ - Immediate (for urgent message use only)
//WL2K P/ - Priority
//WL2K R/ - Routine (Default)

“Reply” and “forwarded” messages will be treated with the same priority as the original unless the precedence indicator is changed in the subject line when replying or forwarding.

Here are some examples of acceptable subject lines using the precedence indicators:

//WL2K P/Food and bedding inventory request
//WL2K R/Supplies received
Re://WL2K R/Generator manual needed
FW://WL2K R/Please bring Gasoline

The "//WL2K" key informs the mail processing system to bypass the anti-spam whitelist (accept list) and allow the message to be forwarded to the Winlink user should the recipient address be absent from the receiving account whitelist. This key may be changed from time-to-time.

Why is the spam filter so important?
SPAM control on the WL2K system is essential because our licensed radio users and station operators are bound by laws and regulations that prohibit commercial or indecent content contained in most unexpected messages. More importantly, slow radio circuits could be easily clogged with SPAM messages when important, urgent or emergency messages must get through.
