What to do when I get a message "Auto-reply not sent: Too many e-mail to:" in SuperOffice Service?

SuperOffice installation has a feature that help to protect your sending reputation. It gets activated in the situations when the SuperOffice user (or a group of users) are trying to send many emails in a short period to a specific email address (or addresses). Then SuperOffice might prevent delivery of e-mails. 

The rule that prevents sending e-mails uses the values stored in the database table called mail_block. In this table system stores email addresses and numeric values (in the field time_pool). These values are reduced every time an e-mail is sent to the e-mail address and every one-second value is increased by one. The number, which is deducted from the original value depends on the settings in the config database table in the field mb_modifier. When the numeric value next to the e-mail address drops below the value defined in the field mb_treshold, the e-mail sending to this e-mail address is stopped. The initial value of the time_pool field is as the number set in the mb_max_value field. It is the upper (initial) value for the spam-control algorithm, which makes sure that a single email address does not receive too many emails.

Hence by default, the system will permit 1 email message every 10 minutes on average, with a starting buffer of 2 emails. In other words, if you send 3 emails to the same address instantly, the third one will be blocked.

The setup of this feature can be changed, however there is no user interface to do it. The only way to change or disable it is by making a change directly in the SuperOffice database. 

  • If you increase the default value of 1210 in the mb_max_value field - the buffer will increase. That means more emails may be sent before they are blocked. If the value of mb_modifier is decreased, then a bigger number of emails will be allowed to send per time frame.
     
  • f the mb_modifier field value is set to 0, then the rule of preventing e-mail to be sent will be disabled entirely.
     

Note!

  1. Please be aware that we recommend taking a backup before making any changes directly to the database. This FAQ explains how to do it.
     
  2. SuperOffice Online customers should contact SuperOffice support if the changes need to be made.
