Regression introduced by 3891d3e654.
Merging multiple options with type "str" won't work and give an
evaluation error. For extra configuration lines in the Postfix config it
really should be "lines", especially because even the description
mentions "extra lines".

This reverts commit 88f4b75a00 and fixes the
recipientDelimiter config option. Till then the camel case variant was used
while recipient_delimiter would have been right.
This solves the problem of e.g. mutt not finding mail unless the user
sets MAIL=/var/spool/mail/$USER.
The default MAIL variable seems come from bash. Reasons for adding
symlink instead of changing MAIL default in bash:
- No need to rebuild world
- FHS recommends /var/mail over /var/spool/mail anyway[1]. Better fix
NixOS mail location than change MAIL in bash to something that doesn't
work on non-NixOS (however unlikely that users run nixpkgs bash on a
non-NixOS distro...).

Absolute path is required when one has such postfix configuration
where he/she needs to specify the actual (real) path to active dovecot
config.
Without this commit applied, the dovecot is running in such way:
/nix/store/hashAAA-dovecot-ver/sbin/dovecot -F -c /nix/store/hashBBB-dovecot2.conf
and postfix can't be aware of the value of "hashBBB" via services.postfix.extraConfig = '' ... '';
(it can only be aware of "hashAAA" with ${pkgs.dovecot} parameter)
Also enable Restart on-failure.
Edit: set RestartSec to 1s
postfix 2.11 is much more humane with respect to disk writes since it uses
sockets (which do not change inodes on accesses) instead of fifos (which do).
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
That is, you can say
security.pam.services.sshd = { options... };
instead of
security.pam.services = [ { name = "sshd"; options... } ];
making it easier to override PAM settings from other modules.
