I am trying to help someone that is getting the exact same error.

The message he is getting back is:

Fatal error: Uncaught exception 'Swift_ConnectionException' with message 'There was a problem reading line 1 of an SMTP response. The response so far was:
[]. It appears the connection has died without saying goodbye to us! Too many emails in one go perhaps? (fsockopen: #0) ' in C:\wamp\www\SwiftMailer\lib\Swift\Connection\SMTP.php:250 Stack trace: #0 C:\wamp\www\SwiftMailer\lib\Swift.php(306): Swift_Connection_SMTP->read() #1 C:\wamp\www\SwiftMailer\lib\Swift.php(386): Swift->command('RCPT TO: <angel...', 250) #2 C:\wamp\www\Sweepstakes Manager\manager\mail\doMail_YDI08_Grand_Swift.php(145): Swift->send(Object(Swift_Message), Object(Swift_RecipientList), Object(Swift_Address)) #3 {main} thrown in C:\wamp\www\SwiftMailer\lib\Swift\Connection\SMTP.php on line 250

He is running this from a local machine, and connecting to an SMTP server.

He is in process of sending out about 8000 messages. About every 100 messages, he gets this error and the system stops. If he just sends the one email that crashed, he will get the same error, so adding a delay does not help. There appears to be some kind of problem with the email response that Swift does not like. Unfortunately, he does not have access to the mail logs, so debugging this has been difficult, and we have not yet figured out a workaround.

Well, the workaround was to comment out the throw exception.

First, note that the
should not be in the error message because the exception appears to output htmlentities.

The response that we were getting back is a '250 ok' message, and sometimes we would get ' 250 ok' with a space. The ones with a space would throw the exception. A fix might be to trim the response message.
