| 526 | # handled by this ACL as well. |
| 527 | # |
| 528 | # Non-alphanumeric characters other than dots are rarely found in genuine |
| 529 | # local parts, but are often tried by people looking to circumvent |
| 530 | # relaying restrictions. Therefore, although they are valid in local |
| 531 | # parts, these rules disallow certain non-alphanumeric characters, as |
| 532 | # a precaution. |
| 533 | # |
| 534 | # Empty components (two dots in a row) are not valid in RFC 2822, but Exim |
| 535 | # allows them because they have been encountered. (Consider local parts |
| 536 | # constructed as "firstinitial.secondinitial.familyname" when applied to |
| 537 | # a name without a second initial.) However, a local part starting |
| 538 | # with a dot or containing /../ can cause trouble if it is used as part of a |
| 539 | # file name (e.g. for a mailing list). This is also true for local parts that |
| 540 | # contain slashes. A pipe symbol can also be troublesome if the local part is |
| 541 | # incorporated unthinkingly into a shell command line. |
| 542 | # |

| 544 | # from an RFC2822 point of view. We chose to have them blocked by |
| 545 | # default for security reasons. |

| 1744 | # The examples below are for server side authentication, when the |
| 1745 | # local exim is SMTP server and clients authenticate to the local exim. |
| 1746 | |
| 1747 | # They allow two styles of plain-text authentication against an |
| 1748 | # CONFDIR/passwd file whose syntax is described in exim4_passwd(5). |
| 1749 | |
| 1750 | # Hosts that are allowed to use AUTH are defined by the |
| 1751 | # auth_advertise_hosts option in the main configuration. The default is |
| 1752 | # "*", which allows authentication to all hosts over all kinds of |
| 1753 | # connections if there is at least one authenticator defined here. |
| 1754 | # Authenticators which rely on unencrypted clear text passwords don't |
| 1755 | # advertise on unencrypted connections by default. Thus, it might be |
| 1756 | # wise to set up TLS to allow encrypted connections. If TLS cannot be |
| 1757 | # used for some reason, you can set AUTH_SERVER_ALLOW_NOTLS_PASSWORDS to |
| 1758 | # advertise unencrypted clear text password based authenticators on all |
| 1759 | # connections. As this is severely reducing security, using TLS is |
| 1760 | # preferred over allowing clear text password based authenticators on |
| 1761 | # unencrypted connections. |
| 1762 | |
| 1763 | # PLAIN authentication has no server prompts. The client sends its |
| 1764 | # credentials in one lump, containing an authorization ID (which we do not |
| 1765 | # use), an authentication ID, and a password. The latter two appear as |
| 1766 | # $auth2 and $auth3 in the configuration and should be checked against a |
| 1767 | # valid username and password. In a real configuration you would typically |
| 1768 | # use $auth2 as a lookup key, and compare $auth3 against the result of the |
