Problem sending email in HTML format

[Giles_B]

Version: 2008 Operating System: Mac OS X 10.5 (Leopard) Processor: Intel Email Client: pop I use two email accounts, different receiving POP's, but same outgoing SMTP. Email from the SMTP domain address goes fine as both HTML and plain text, but email from the second account will not send in HTML format, except to itself.

This started about 3 months ago and i cannot find anything wrong - deleted and reset the email account, but i still get the following error message:

5.7.1 o0DNM1mH019690 This message does not comply with required standards.

The letters and numbers change but same text message. I'd be grateful for any help and wonder whether its just me having this issue.

but email from the second account will not send in HTML format, except
to itself.

That looks like a server issue. Are you sure there is no filtering on
your SMTP server?
