Enable null sender ('MAIL FROM:') messages to be accepted by XMail.

In the business world, end users only care if the recipient received the email they sent. They don't not know or care anything about RFC compliance.

[xmail] Re: spam-address.tab size
I am already using SORBS and I see in the SMTP log that a lot of messages are rejected because of SORBS. But I still get a lot of spam from other servers that SORBS don't seem to know about. I checked on the SORBS web site to see if there is a way to report spammers but I only found information on how to be taken off their list. Surely if we're all forming our private lists of spammers, is there not a way for us to work collectively and submit the addresses we collect to some organisation that we can all use for blocking spam? I have a growing database now of spam messages that shows such things as the sending IP address, the mail-from address, recipient and subject. I just don't know who I can give this to so others can benefit. If we all work collectively, we might quickly rid the world of spam.

[xmail] 1.23 changelog ...
Ok, so far this is what's inside 1.23 changelog: - Check the mailbox size for every message coming into the mailbox (before it was only done during the SMTP phase). - Do not try to send to the 'A' record if the recipient domain does not exist at all (NXDOMAIN). Bounce immediately instead, avoiding lengthy retry policies. - Added the wlex flag to filter lines (works for the SMTP ones only), to exclude execution of the filter line in case the client IP is white-listed inside the ipprop file. - Added the post-RCPT SMTP filter, that is called before XMail acks the client recipient. A new RCPT=EFILTER long entry is emitted in case a recipient is rejected by a filter. - Added @@CRCPT (current recipient) and @@FROM (sender email address) macros to SMTP filter substitution. - Allow cmdaliases to work on aliased domains. Before a cmdalias defined on an alias-target domain was not working before the cmdalias check was done before the alias domain resolution. - Added the ability to bypass the SMTP.IPMAP.TAB inclusion using SMTP authentication. - Added a new SERVER.TAB variable SMTP-IpMapDropCode to control the drop code to be used for IPs listed inside the SMTP.IPMAP.TAB. Like other codes inside XMail, 1 means drop now, 0 means allow if auth, and -N means add N seconds delay. An immediate drop will emit a SNDRIP=EIPBAN log entry. - Added a new SERVER.TAB variable SmtpMsgIPBan to control the SMTP message returned in case of SMTP.IPMAP.TAB inclusion. - Added log message when the maximum number of SMTP/POP3/CTRL threads is hit. - Fixed documentation about the spool info line and the SMTP filters info line. - Fixed a build problem on OpenBSD related to the lack of c_r (reentrant C library) library. - Fixed greetings message to be RFC2821 compliant (server host must be first). - Fixed a NAME_MAX build error ond *BSD and Solaris. - Added a Pop3ScanCur USER.TAB variable to control the scan of the Maildir's cur directory during POP3 message list build. Now XMail only scans the new directory as default. I'd call that a day, and I'll be making a pre-release possibly tomorrow. OT section Some of you might have thought that I somehow forgot about that.
