Delivery errors and resolution

If errors arise during the e-mail send and, you need to abort the process, go to Settings / Common settings / tab SMTP” and customize the default settings. You can then restart the sending process – click the black down arrow next to the Start button and select the appropriate option (resend to unsent e-mail addresses or resend to failed e-mail addresses).

You can also save a delivery report. Click Reports… in the Sender Mail Monitor and specify the parameters for report generation: the kind of e-mails to be saved and their format.

You can see a list of errors and their resolutions in the Atomic Mail Sender User Manual in the About errors section.

Each SMTP provider has their own value for delivery error codes. Error codes start with 400-… and 500-….

Below are the most common delivery errors and their resolutions:

Errors with recipient’s e-mail

550 Message was not accepted — invalid mailbox. Local mailbox  name@mail.ru is unavailable: user not found

RSET

This e-mail account doesn’t exist.


450: Requested mail action not taken: mailbox unavailable.

 Server cannot access the recipient’s mailbox to deliver an e-mail message. This may happen as a result of cleaning dead addresses from the server, the mailbox is corrupted, or the mailbox is on another server that is temporarily unavailable. This error may also be caused by the network disconnecting while sending, or an extended server stops receiving mail from your server for some reason (IP address, blacklists, etc.).

Repeated attempts to send e-mail messages to this mailbox can be successful.


501: Syntax error in parameters or arguments.

Invalid e-mail addresses or domain name. Sometimes this error indicates a network connection problem.

Verify recipient’s e-mail address for domain name validation (there may be spelling errors or invalid domain name). Try to resolve any connection problems.


512: The host server for the recipient’s domain name cannot be found (DNS error).

A problem arose with the DNS server while attempting delivery or the recipient’s email address is invalid.

Verify the recipient’s e-mail address for domain name validation (correct any spelling errors or invalid domain name).


523: The recipient’s mailbox cannot accept messages of this size.

The message size (the message itself plus any attachments) reaches or exceeds the recipient’s server limit. Check the size of the email message you want to send, and pay particular attention to attachments. You may need to split this message into several smaller ones.
