Disconnection errors from SMTP server
When sending bulk emailings using SendBlaster this is a common error message:
email@example.com: Disconnected from server
firstname.lastname@example.org: Disconnected from server
Let’s see some solutions to the “disconnected from server” problem:
If part of the email letters were sent Ok, Disconnection error may occur because of too many simultaneous connections to the SMTP server: try lowering the number of connections: set simultaneous connections to 1
If you’re on a slow connection, and your email message is big in size, the disconnection error may occur because of a timeout on SendBlaster’s side: try increasing the timeout value (as a test, try with a very long one, i.e. 300secs)
Another possibility is that you enabled Direct Send as a backup method (”use direct send in case of error”), but the recipients’ servers are not allowing that; we suggest that you switch it off.
If this does not help, please contact our email marketing support and give us a log of the mailing (you’ll find it in “History”) and a screenshot of your “Send” form settings.
