Mailwasher error message

[Nuclear Krusader]

What does it mean?

Could not send - the SMTP server replied:
5.7.1 <MAILER-DAEMON@leon.podernet.com.mx>... Access denied
(SMTP Server error 550)

I am getting it whenever I try to bounce the spam mails.

TIA for your input.

Don't bounce spam mails. Forging fake replies is every bit as wrong as spam is to begin with.

You're getting the message because your ISP (rightfully) won't let you relay fake mail.

Ah, ok. Then I'll keep just deleting them. Thanx. :)

[PhiloVance]

Ah, so.

I got those too; thanx for the heads up, xayd!
