Hi. I recently get a lot of spam (probes?) which is refused by cyrus/lmtpd (version 2.2.12 from the Debian/experimental packages) because of a missing header/body seperator. Since this happens late in the queue, this leads to unwanted backscatter.
However, it seems to me that the standards (both SMTP and LMTP) allow mails to consist of just a bunch of headers, without any body and thus, without any header/body seperator. For me, this looks as if there are two alternatives: 1) I overread something in one of those standard documents which requires such a seperator. If this is true, could someone please point me to the right paragraph? 2) Cyrus/LMTPD is wrong in denying these mails and should be fixed. In any case, the fix to be done in Cyrus for these mails would be rather simple: Introduce a single empty line at the end of the message instead of refusing the message. "Be strict in what you deliver and lax in what you expect." That has always been a good advise regarding interoperability of software. regards, Sven ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
