Solve an error "Spam Message Rejected"

This guide will allow you to solve a problem if you obtained in return, after sending an e-mail, a message with the reason for failure " Spam Message Rejected" or " 5.7.0 AV: Message is referred by headers rule filter.. 554 Please check the message and try again" ...

Must be checked

Check that your e-mail did not include:

• words or phrases that are often associated with spam, as it could be identified as an unwanted and rejected message
• any unusual indication in the signature, an erroneously formulated link (http//.domain.xyz e.g.), etc.
• an attachment with one of these prohibited extensions: .exe, .com, .cmd, .cpl, .hta, .scf, .sct, .lnk, .bat, .js, .jse, .wsh, .ws, .wsf, .wsc, .vbe, .vb, .vbs, .shs, .pif, .scr ... including inside a compressed file (.zip e.g.)

To send a file (js or exe e.g.) and whose absence of virus is confirmed, store it on your hosting space and link it to it (if the file is bulky and send it from the Mail Infomaniak Web app (online service) mail.infomaniak.com), it will in any case be placed on a temporary server allowing the sending to your correspondent who will receive in this case a download link) or via Swisstransfer.com.
 

Also check your SPF registration If your domain does not have an SPF record or if this record is incorrect, it will most likely result in the rejection of your message.
