Joshua Tauberer d510c8ae2a Enable and recommend port 465 for mail submission instead of port 587 (fixes #1849)
Port 465 with "implicit" (i.e. always-on) TLS is a more secure approach than port 587 with explicit (i.e. optional and only on with STARTTLS). Although we reject credentials on port 587 without STARTTLS, by that point credentials have already been sent.

Michael Kroes a52c56e571 only set the CN field when generating initial CSR to prevent issues with the php7 ppa version of openssl (#1223)
OpenSSL 1.1.0f now validates the other subject fields and rejects the empty string (for the country?) because it isn't two characters.

Joshua Tauberer 4f2b223070 add comments about how openssl generates random numbers for genrsa and what could create a perfect storm to make the key not random

Joshua Tauberer 73fbcd7fa3 silence all of the installing/already installed package messages on installation
Querying dpkg for each package is slow, and we have way too much output on installation because of it.

Joshua Tauberer 5fd107cae5 more work on making the bash scripts readable 2014-10-04 17:57:26 -04:00
Joshua Tauberer 39bca053ed add 2048 bits of DH params for nginx, postfix, dovecot
nginx/postfix use a new pre-generated dh2048.pem file. dovecot generates the bits on its own.

ssllabs.com reports that TLS_DHE ciphers went from 1024 to 2048 bits as expected. The ECDHE ciphers remain at 256 bits --- no idea what that really means. (This tests nginx only. I haven't tested postfix/dovecot.)
