While looking through the Postfix default configs about TLS ciphers, I noticed these
grep -i " anull" main.cf.default tls_export_cipherlist = aNULL:-aNULL:HIGH:MEDIUM:LOW:EXPORT:+RC4:@STRENGTH tls_high_cipherlist = aNULL:-aNULL:HIGH:@STRENGTH tls_low_cipherlist = aNULL:-aNULL:HIGH:MEDIUM:LOW:+RC4:@STRENGTH tls_medium_cipherlist = aNULL:-aNULL:HIGH:MEDIUM:+RC4:@STRENGTH What's the reason for the aNULL:-aNULL ? That's not making sense to me. Doesn't that just remove what you just added? Is it a logging thing? Jason
