[gentoo-user] I can't send attachments

[Michael Sullivan]

I tried to send a comic strip as an attachment to my wife and I got a
Mailbox Unavailable error.  I'm running:

baby log # emerge -pv exim

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] mail-mta/exim-4.68  USE="exiscan exiscan-acl ldap mysql
pam perl sasl ssl syslog tcpd -X -dnsdb -domainkeys -dovecot-sasl
-gnutls -ipv6 -lmtp -mailwrapper -mbox -mbx -nis -postgres -radius -spf
-sqlite -srs" 0 kB 

Total: 1 package (1 reinstall), Size of downloads: 0 kB

And here's my exim.conf file:

I have removed a lot of whitespace from this listing.  Does anyone have

The "Mailbox Unavailable" sounds like an error in the form of an e-mail
bounceback from the e-mail address' server you were trying to send to.
Sometimes I see this error working in tech support (cable modem).  I doubt
it's anything on your end.

...and so should be exim's logs, right? I usually find it easier to read
actual error reports than (stripped) configurations for complex
software that is claimed to be responsible for the error...

Also, I have a hard time trying to understand the problem. A mailbox
unavailable shouldn't occur after SMTP's "DATA" command, it should
happen after the "RCPT TO" (answer code 450). At that point, no data has
been transmitted, so the error does not make sense except if it is
wrongly phrased by the MUA or (sorry) you. SMTP doesn't allow it at
that point. There's only the possibility for much more general error
codes. BTW, what's the MUA? You just introduced the MTA. Did you try
another one?

We use evolution.  I tried using Squirrelmail and got this:

Message not sent. Server replied: 
        Requested action not taken: mailbox unavailable
        550 Rejected: spam score 6.5

Ah, I see. Exim does output a 550 anyway (and it makes some sense, I
guess the SMTP protocol definition is impractical w/ regard to the
allowed errors). But reading the full error report, it seems it's your
spam detection software that leads exim to deny the mail. Your exim
config seems to indicate that everything with a spam score > 6.0 is to
be denied (those numbers in the config are given with a factor of ten,
I guess?). Depending on whether the full spam check report is available
on the logs, you might want to temporarly disable that mail denial and
check the mail headers for the protocol of which certain spam checks
leads your spam filter to the conclusion it is spam, then adjust that.
