I'd say, by the name of the attribute.

Here comes a shorter patch. I'll test yours too.

diff --git a/src/src/lookups/ldap.c b/src/src/lookups/ldap.c
index f77229d..ef7ed9e 100644
--- a/src/src/lookups/ldap.c
+++ b/src/src/lookups/ldap.c

             DEBUG(D_lookup) debug_printf("LDAP attr loop %s:%s\n", attr, value);


-            if (values != firstval)
+        /* In case we requested one attribute only but got

+        if ((attr_count == 1 && data) || (values != firstval))
               data = string_cat(data, &size, &ptr, US",", 1);


             /* For multiple attributes, the data is in quotes. We must escape


For testing I'm using the following LDAP entry:

    dn: uid=heiko,dc=schlittermann,dc=de
    x-MailPrimaryAddress: hs@???
    description: a
    description: b,c
    x-MailAlternateAddress: h,e@???
    x-MailAlternateAddress: heiko@???
    x-MailAlternateAddress: heiko@???


$ ../../build-Linux-x86_64/exim -be '${lookup ldap{ldap:///dc=schlittermann,dc=de?mail?sub?uid=heiko}}'
hs@???,h,,e@???,heiko@???,heiko@???

$ ../../build-Linux-x86_64/exim -be '${lookup ldap{ldap:///dc=schlittermann,dc=de?description,mail?sub?uid=heiko}}'
x-MailPrimaryAddress="hs@???" description="a,b,,c" x-MailAlternateAddress="h,,e@???,heiko@???,heiko@???"


But, I'm not sure if I didn't break anything else :)
