sendmail.exe is a simple windows console application that emulates sendmail's "-t" option to deliver emails piped via stdin.
it is intended to ease running unix code that has /usr/lib/sendmail hardcoded as an email delivery means.
it doesn't support deferred delivery, and requires an smtp server to perform the actual delivery of the messages.
or download the installer (for bugzilla installs).
some people have has performance issues using my fake sendmail with gmail's smtp servers (due to SSL/TLS). msmtp may be a viable alternative to fake sendmail.
generally all you need to do is install sendmail.exe in \usr\lib, and existing code that calls /usr/lib/sendmail will work.
if you're coding new applications, all you need to do is construct your email message with complete headers, then pipe it to /usr/lib/sendmail -t
for example, to use fake sendmail from the command line:
@ECHO OFF REM send email from command line via SMTP with sendmail ECHO From: byron@example.com > %TEMP%\temp.mail ECHO To: someone-else@example.com. >> %TEMP%\temp.mail ECHO Subject: this is a test >> %TEMP%\temp.mail ECHO.>> %TEMP%\temp.mail ECHO testing. >> %TEMP%\temp.mail ECHO blah blah.. >> %TEMP%\temp.mail ECHO. >> %TEMP%\temp.mail ECHO blah. >> %TEMP%\temp.mail sendmail -t < %TEMP%\temp.mail DEL %TEMP%\temp.mail
note ECHO. puts a blank line in the file, not a line with a single period on it.
note: if you have IIS installed, you can send emails without any third party programs (you do NOT need my sendmail wrapper).
@ECHO OFF REM send email from command line via IIS REM change this path to point to IIS's pickup directory SET root=c:\InetPub\MailRoot\Pickup REM set up temp and eml filenames IF NOT EXIST %root%\temp MKDIR %root%\temp :setTempFileName SET tmp=%RANDOM% IF EXIST %root%\temp\%tmp%.tmp GOTO setTempFileName SET eml=%root%\%tmp%.eml SET tmp=%root%\temp\%tmp%.tmp REM build the email. ^ is the escape character ECHO From: bob.smith@example.com> %tmp% ECHO To: sally.jones@example.com>> %tmp% ECHO Subject: Example>> %tmp% ECHO Content-Type: text/html>> %tmp% ECHO.>> %tmp% ECHO ^<b^>This is a test^</b^>>> %tmp% REM move the temp file into the pickup directory for delivery RENAME %tmp% %eml%
i've had a few reports of sendmail returning a "range check error". i have tracked this to a bug in the indy sockets library and it has been fixed in version 18. see bug 63 for details.
some anti-virus product limit what applications are allowed to send mail via port 25 (SMTP). ensure that sendmail.exe is in your list of approved applications.
socket error 11004 means that the dns server which sendmail is talking to does not have a record of the appropriate type for the com puter name which it was looking up.
this can happen if the dns server is currently incorrectly configured (check with your isp, or whoever is running the dns server you are using) or because you should be using a different computer name which would have an a record defined.
in some cases it can also happen because you are using the incorrect dns server addresses (eg using the dns servers of one isp when you are dialing into a second isp).
it means that you have been denied access to that smtp server by its administrator. administrators prevent abuses of their smtp relay servers by requiring that you send e-mail only from a computer connected to their network, or that you use some type of authentication.
talk to the server's administrator and ask what are the requirements for connecting to the server. sometimes, the server may need to be reconfigured.
uncomment the debug_logfile entry in sendmail.ini resend a failed message. this should create debug.log in the same directory as sendmail.exe showing the complete SMTP transcript.
if you require assistance in setting up sendmail, please follow the directions on the help page.
