CC_SMTP_AUTH question not in documentation
Posted: 18 May 2014, 14:58
I know that blocking countries in iptables is bad news - particularly if they run into 1,000 and more.
What is not clear to me is the consequence of having an absolutely huge /etc/exim.smtpauth file based on the new feature you recently provided.
For Example allowing all countries except for a few dozen would be pretty much most of the IP range. Would this kill EXIM?
The CPAN Net::CIDR package can help with this by concatenating very long lists and joining them where possible. For example, the USA shows 45,581 CIDR's. After running it through Net:CIDR it comes down to 15,340
The question still remains; what is the best guestimate on how many CIDR's would be "safe" to put into /etc/exim.smtpauth before things start slowing down?
