[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:

And here's my exim.conf file:

I have removed a lot of whitespace from this listing.  Does anyone have
any ideas?  We just noticed it this morning, as we very rarely send
attachments.  We can still send attachment-less emails normally.
