Hello,

This is from "Yahoo's Book - Wen you less expect we'll reject your email". :)
Limit the messages you send per connection
Yahoo Mail accepts a maximum of 20 messages per SMTP connection. We encourage you to cap the number of messages you send to Yahoo Mail to fall within this per-connection limit.

How can be done?
Of course only for Yahoo domains.

Thanks!
Lucian

Hello :)

You can browse to:

"WHM Home » Service Configuration » Exim Configuration Manager » Advanced Editor"

Add an additional configuration value for:

smtp_accept_max_per_connection

Set it to a value such as 20 to meet Yahoo's requirements.

Thank you.

Hello,
according to exim documentation
smtp_accept_max_per_connection Use: main Type: integer Default: 1000

The value of this option limits the number of MAIL commands that Exim is prepared to accept over a single SMTP connection, whether or not each command results in the transfer of a message. After the limit is reached, a 421 response is given to subsequent MAIL commands. This limit is a safety precaution against a client that goes mad (incidents of this type have been seen)
