SMTP Error (452)

[ben_magee]

Whenever I try to send an email, I get the following message:

"SMTP Error (452): Failed to set sender "[email protected]" (4.3.1 Insufficient system storage)."

Is there a way that this can be resolved? I have tried to free up storage by deleting old messages but after 200 deletes I am still receiving the same message.

That error comes from your SMTP server, you are not responsible for that then you should contact the person who is.
