EMAIL REJECTED badmailfrom
« on: April 23, 2026, 06:09:16 AM »
guys please can you help the noob

I have a User that has received a mail message from an external client With Attachments

the user does get the email, However when the User Forwards the Mail Message to any Internal User the Mail gets rejected and not delivered

When the Same User forwards the message to a Gmail Account it Does get Delivered to any Gmail Account

Why and How can i get the Message to Be Delivered to Internal Users?

I have noticed that if i REMOVE the Attachments the Mail DOES Get Delivered  however the Same Mail Message Forwarded WITH THE Attachments Does get Delivered to any Gmail Account

eg of the error:

2026-04-23 05:35:05.399796500 8982 dispatching MAIL FROM:<frominternaluser@mysmeserver.com> SIZE=6348230

2026-04-23 05:35:05.402242500 8982 (rcpt) rcpt_ok: skip, relay client

Configure email client to send via port 465 SSL (or 587 TLS) and authenticate sending user with password, not via port 25 without auth.
