I already did 1) - that's working fine.
2) is becoming frustrating.  I thought net_ip2addr() would be what I
needed, but I guess not.  Although I only used (char *type) not (const
char *type)..   No compile issues, nothing.  It doesn't appear to even try
and write to the table. (I locked the table to see :)

For giggles I tried using checkpassword just to see what would happen
(though I know it works for qmail-pop3d), but apparently Dovecot can't use
checkpassword with CRAM-MD5 :/   Not sure if that's a bug or expected, but
means I can't convert.  I don't want to remove functionality.

I don't expect much more help unless you see something jump out - This
function just returns an error if MySQL throws an error (in vpopmail's
vauth.c), any other errors and it's silently skipped over - so
troubleshooting this is going to be a little drawn out.

Thanks,

Rick

1) You need to modify vpopmail's vset_lastauth() function to actually
support this.

2) Once you do have the extra field (const char *ip) added, you can use:

vset_lastauth(vpop_user, vpop_domain,
net_ip2addr(&auth_request->remote_ip),
t_strdup_noconst(auth_request->service));

Or maybe you could use vchkpw with Dovecot too via passdb checkpassword?

[Dovecot] Help - custom vpopmail

[Rick Romero]

Hi,

 First, I'm not sure if dovecot should alter this, but it seems vpopmail
writes the IP into the 'remote_ip' field instead of the auth type. Dovecot
still writes the auth type.  I want both.

 So I modified my vpopmail install to write an additional field into the
lastauth table.  My custom vpopmail writes the remote IP into remote_ip,
and the auth type into a 'type' field. I tested with qmail's POP3 daemon to
verify vchkpw would fill the table correcly.

 But I'm not sure how to get dovecot to do it:

 I know this is close, but there is something not right in
src/auth/userdb-vpopmail.c line 99.
 vset_lastauth(vpop_user, vpop_domain, &auth_request->remote_ip,
t_strdup_noconst(auth_request->service));

 I'm, by far, NOT a C programmer - Feel free to laugh at my code publicly
:)

 Thanks,

 Rick
