Common Email Errors

In this blog post, we will cover some of the most common email error messages you may come across while sending/receiving emails. Some of the error messages aren’t that helpful at explaining what the real issue is.

553 sorry, that domain isn’t allowed to be relayed thru this MTA

First ensure you’re using the correct inbound/outbound mail server. This should be set to mail.pipeten.co.uk within your email client. We would also recommend double checking the settings within your email client:-

554 sorry spam detected by SpamAssassin

If you see this error message it means the spam assassin service believes the content of the email resembles spam and will prevent the email being sent. This is to help prevent spammers from sending out spam emails.

We have a blog post which provides ways to avoid email being marked as spam which can help prevent your emails being incorrectly picked up as spam.

550 sorry, no mailbox here by that name / Invalid recipient

This is one of the more straightforward error messages, it simply means the email address you’re trying to send your email to doesn’t exist on the mail server. This could be due to the mailbox being deleted by the user or an incorrectly typed email address.

If someone is seeing this error when attempting to send you an email, first ensure they have the correct email address. If you have provided someone with an email address you haven’t currently setup this can be fixed by logging into you hosting account and creating the mailbox.

Emails aren’t coming through

If you find the emails being sent to one email address seem to just disappear and never reach your email client it’s possible the mailbox has been blocked due to a breach of the Pipe Ten mail policy. If you send in a support ticket one of our engineers will be able to take a look into this and if the mailbox has been blocked confirm what you need to do to have the block removed.

If you have tried all of the advice above but still can’t get your email client to work feel free to speak to one of our engineers on live chat or send in a support ticket from your hosting account.
