255 spam rejected

[#1]

I'm receiving 'SMTP error from remote server for TEXT command, host: mx.avasin.plus.net (212.159.9.200) reason: 552 Spam Message Rejected' on emails which are replying to one particular address. The emails contain nothing of note but do have pretty small attachments.

Despite the error, some do seem to get through but there's no sign they have until or unless I get a reply to them.

Anyone any thoughts?

Hey there @digitl what domain is the email address? Is it a Gmail or another one? Just for clarification.

Hi Will

Hi, could you drop us a PM please with the full rejection error you're getting. We can then raise this to our back office team to investigate.

Hi Claudia

Thanks for the response.

I've PMd the entire source of the email which includes a little back and forth in terms of replies.

Hope that helps.

Best wishes

Hi Claudia

Another 255 rejection (which I have had several times previously). Like the other 255, I quoted the original email with its images so was quite big. Could that be the issue?

I will send the source in a PM again.

Best wishes

Frank
