I'm setting up an Exim 4.87 mailserver with virtual domains stored in a MySQL database. The machine has a hostname of athena.example.com (the example.com of course being fictuous). I want to be able to send as user@example.com.
Local delivery to these virtual users works, so I know the tables are read properly. I added this to my /etc/exim/config:
domainlist local_domains = @:localhost:${lookup mysql{SELECT domain FROM domains WHERE type='local' AND domain='${quote_mysql:${domain}}'}}
..as seen in many examples.
+------------+-----------------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+------------+-----------------------+------+-----+---------+-------+
| domain | char(128) | NO | MUL | | |
| type | enum('local','relay') | NO | | local | |
| relay_host | char(128) | NO | | | |
+------------+-----------------------+------+-----+---------+-------+
Now, when sending mail to a remote host, something odd happens:
$ /usr/lib/sendmail jvo@my.real.domain
Subject: Test 1
foo
.
Log:
2016-08-21 00:56:41 1bbFBm-0005ZL-0D <= jvo@athena.example.com U=jeroen P=local S=382

2016-08-21 00:56:43 1bbFBm-0005ZL-0D Completed
This gets delivered with a From: of jvo@athena.example.com, as is to be expected.
$ /usr/lib/sendmail jvo@my.real.domain
Subject: Test 2

foo
.
Log (similar to the first one)
2016-08-21 00:57:32 1bbFCT-0005ZT-O5 <= jvo@athena.example.com U=jeroen P=local S=427

This gets delivered with a From: of jvo@example.com, without the 'athena' part. So far so good.
Now, when I try to send mail using authenticated SMTP, the FQDN gets added to the mail! The end result is
"jvo@example.com"@athena.example.com
which of course gets rejected. The quotes are added as well (and yes, it is correctly set in my mail client).

So at the moment I'm stuck... any idea what could be wrong?
