Hi,
I don’t know if it’s the good place but I don’t know where to post.
Here is my issue : Everytime I try to create or reply to an email with a lot of recipients, all my emails from my @e.email address sent to @gmail.com mailboxes (sometime also @free.fr) are blocked and I receive a non-delivery message error with this code :
Diagnostic-Code: smtp; 550-5.7.1 [51.75.90.184 11] Our system has detected
that this message is 550-5.7.1 not RFC 5322 compliant: 550-5.7.1 ‘From’
header is missing. 550-5.7.1 To reduce the amount of spam sent to Gmail,
this message has been 550-5.7.1 blocked. Please visit 550-5.7.1

review RFC 5322 specifications for more information. r6si12659647wmf.104 -
gsmtp
Of course the link doesn’t help at all because there is a From header, it’s my address @e.email. Is there any way to fix this or a workaround ? If I can’t even send emails to multiple recipients I will have to back to my gmail account and I’d rather not !
Thank you
