Dear Bjorn,

Every time I send an email to the PCI main list, I will send it to 
myself first, but I have encountered the following problems:
Whether I send my personal 163 email, Outlook email, or my company's 
cixtech email, only 10 patches can be sent. So in the end, I sent each 
patch separately.

This is the first time I have sent an email with a series of more than 
10 patches. My configuration is as follows:
smtpserver = smtp.163.com
smtpserverport = 25
smtpenablestarttlsauto = true
smtpuser = 18255117159@....com
smtppass = xxx

I suspect it's a problem with China's 163 email. Next, I will try to 
send it using the company's environment. Or when I send this series of 
patches next time, I will paste the web link address of each patch in by 
replying 0000-cover-letter.patch.

Thank you very much for the hint you gave.
