I have trying to send emails from my Thunderbird client and have started getting "Too many messages (2.3.2.3) from 51.9.75.183. Please check the message and try again." I have read my forums on this but none have really answered the question. I am now not able to send a single message - even though I have left this overnight. I presume this is a setting on an email server. I need to send out a number of important emails but not currently able to.
