Sendmail ignores MaxMessageSize value
Terra Dactyl
In a nut shell...
Help! I'm using Sendmail version "Sendmail 8.12.11/8.12.11" on SuSE
Linux 9.1
My /etc/mail/sendmail.cf file says;
# maximum message size
O MaxMessageSize=10000000
(thats 7 zeros)
Yet sendmail insist on rejecting messages with more than a 1 meg file
attachment with a the followign message;
-----------------------------------------------
552 5.3.4 Message is too large; 1000000 bytes max
554 5.0.0 Service unavailable
(thats 6 zeros)
------------------------------------------------
Sendmail has to be reading my sendmail.cf file because it figures out
which DNS blacklist I want to use and blocks incoming spam
accordingly.
Yet sendmail insist on rejecting messages with more than a 1 meg file
attachment. Any ideas why?

Which MTA actually gives that message?
Are you sure it's your daemon (that uses the cf file)?
Did you check the EHLO reply?
telnet localhost 25
EHLO my.host
...
What's the message size (SIZE) listed?
--
A: Maybe because some people are too annoyed by top-posting.
Q: Why do I not get an answer to my question(s)?
A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?

Pine as the email client in this instance, but I get the same results
when using Windows mail clients (Netscape Mail and Eudora Pro).

I found the problem, and fixed it. The default config.mc I modified
for my install has the following line in it;
config.mc:define(`SMTP_MAILER_MAX', `1000000')dnl
I commented out the "config.mc:define(`SMTP_MAILER_MAX',
`1000000')dnl", but it still defaulted to 1000000. I had to redefine
SMTP_MAILER_MAX' to 10000000 which leads to the next question.
Why are there two variables for the same thing expecially when
SMTP_MAILER_MAX overrides MaxMessageSize, and the default value for
SMTP_MAILER_MAX appears to be 1000000?

You probably didn't comment it out - '#' doesn't work as a comment char
in .mc/m4 files, use 'dnl ' at the beginning of the line.
>Why are there two variables for the same thing expecially when

From cf/README:
confMAX_MESSAGE_SIZE MaxMessageSize [infinite] The maximum size of messages
that will be accepted (in bytes).
^^^^^^^^^^^^^^^^^^^^^
SMTP_MAILER_MAX [undefined] The maximum size of messages that will
^^^^^^^^^
be transported using the smtp, smtp8, esmtp, or dsmtp
^^^^^^^^^^^^^^^^^^^^^^^...
mailers.
I.e. you could have confMAX_MESSAGE_SIZE > SMTP_MAILER_MAX and still
accept messages > SMTP_MAILER_MAX for e.g. local delivery. And as you
can see, neither limit is set by default - nor in any "default" .mc file
shipped with sendmail (your OS vendor may ship something different).

I removed SMTP_MAILER_MAX from the sendmail.mc and re-built the
sendmail.cf. It works without conflict now. Thanks for everyones
help.
