* OpenSSL 1.1 compatibilityManuel Mausz2018-06-278-137/+125
| | | | | | | | | | | | | | This adds compatibility for OpenSSL 1.1 Since renegotiation is removed from TLS 1.3 we also removed support for authentication via client certificates (control/tlsclients). In general this is still supported by TLS 1.3 however I'm just lazy and we don't need this feature anyway. This also adds optional support for OpenSSL configuration commands for qmail-smtpd and qmail-remote. Commands are loaded from control/opensslconf. For a list of supported commands see https://www.openssl.org/docs/man1.0.2/ssl/SSL_CONF_cmd.html#SUPPORTED-CONFIGURATION-FILE-COMMANDS

* SMTPUTF8: substract null terminationmanuel2017-10-101-0/+1
| | | | | qmail-remote assumes host is not null terminated. IDN requires null termination so subtract the trailing NULL after appending.
* SMTPUTF8: convert UTF-8 domains to IDNAmanuel2017-08-182-2/+31
| | | | | | | | | | | | | This isn't entirely correct according to RFC 6531 as it's better to not convert at all. However this would require we additionally add the UTF-8 form to qmails local recipient users/domains. Plus our SMTPUTF8 implementation doesn't convert outgoing UTF-8 mails if receiving MTA doesn't support SMTPUTF8. So mail forwarding might generate a bounce the user very likely doesn't understand. As MTAs who support SMTPUTF8 most likely also support the IDNA form, always converting is probably a good trade-off.

* Treat ECONNREFUSED the same as ETIMEDOUTmanuel2014-05-203-1/+9
| | | | | | | | After an SMTP connection attempt times out, qmail-remote records the relevant IP address. If the same address fails again (after at least two minutes with no intervening successful connections), qmail-remote assumes that further attempts will fail for at least another hour.
* Remove qmail-remote workaround that Dan Bernstein added on 1996-10-03...manuel2014-05-201-1/+1
| | | | | | ...to work around a bug in BIND versions earlier than version 4.9.4 We don't use the code any more but it does no harm.
* Increase memory buffer from 256 to 8kmanuel2014-05-201-2/+2
| | | | | | | | This patch increases the size of the memory buffer that qmail uses when querying the system for a list of all local IP addresses. This mailing list message describes the problem and includes the patch file. see http://www.mail-archive.com/qmail@id.wustl.edu/msg20935.html
* Fix qmail-remote to handle multiple MX records correctly as in rfc2821manuel2014-05-201-2/+3
| | | | | | | | This patch changes qmail-remote to skip over MX servers that greet with codes 400 to 499 and to bounce mail when any MX server that qmail tries greets with a code 500 to 599. see http://www-dt.e-technik.uni-dortmund.de/~ma/qmail/patch-qmail-1.03-rfc2821.diff
* get rid of DNS ANY querymanuel2014-02-181-24/+4
| | | | | | | | UltraDNS started blocking UDP-ANY queries so this is a problem. This will disable domain canonicalization of the envelope address of outgoing messages. This is as specified by RFC 1123 section 5.2.2. However this requirement is obsolete and modern MTAs have disabled it too.

| | | | | | | | | | | This patch corrects a small programming error in the blast() routine of qmail-smtpd.c. This is sometimes referred to as the "Guninski" bug, in reference to its discoverer. see * http://www.guninski.com/qmailcrash.html * http://thedjbway.b0llix.net/qmail/patches/qmail-1.03.smtpd-blast.patch
