Program will not send emails and shows an error

When I attempt to send any email, I get a message saying "message blocked for containing spam-like characteristics followed by a code 5.7.1 26EK ________

That can happen for many reasons particularly with major SMTP servers such as Google, Microsoft, Apple etc who have strict policies on sending mail.

Common reasons you can get this error.

You might have “some wording in your email” that the SMTP server does not allow and thinks is then suspicious.

Or

You might have “html or other links” in your email that the SMTP server does not allow and thinks is then suspicious.

Or

You are trying to send emails “to too many recipients at the same time” so the SMTP server does not allow it for spam reasons.

So first thing is “try sending a new email” to “only one recipient” with just plain text and maybe a picture without any html links and see if that sends ok. If that works then you know the problem is something in your previous emails.

However if you still cannot send even a normal basic plain text email to just one recipient, then contact your SMTP server technical support.

Hey @ricker

As @cyberzork says it is an SMTP error code.

It is a Microsoft Exchange error code, go here for information:

¡Buena suerte!
