Did Domino 8.5.2(FP1 or HF16) break SMTP?

A discussion on the lnotes-l email thread led me to check on a clients environment to validate Mike's sanity.

It seems that in the course of upgrading to 8.5.2(in my case 8.5.2 fp1 on client side, 852 HF16 on server) of his domain something broke in the outbound SMTP.

Some background first. In clients with Exchange and Domino it is quite common to have one or the other handle inbound/outbound email. Usually we use Domino for in/out SMTP and any email that needs to go to the other parts of the company on Exchange get addressed as joe@company.local instead of joe@company.com. So in all Exchange users listed in Domino they have a forwarding address joe@company.local.

The way Domino used to send external emails would be if I cc'd or included an Exchange user, the outside party saw joe@company.com, not joe@company.local.

However right now Domino is sending out as joe@company.local since the upgrade(and possibly since going to 852).

While I thought the issue was related to Mike's usage of the Dircat, I mean Mobile Directory for you new admins, that is just a red herring.

iNotes sends an email out properly still when I tested it. So whatever is broken, is only 1/2 broken and evidently has to do with the Notes client side OR the Notes Client 852fp1 hitting 852hf16 has an issue.

So anyone out there who has seen this or wants to provide some insight let us know. Guess it's the Iris lab for me on this one at LS11 if nothing comes up first.

One thing I have never really dug into is all the RFC's and how they got implemented, I am just not THAT geeky although someone in Product Management usually knows these things. Used to be many years ago my friend Mike Harer owned SMTP but these days who knows.


  1. Keith,

    You know for sure that you have enabled the option on the config document of your outbound server that it should convert all addresses and not only the addressed one !

  2. Check to be sure that joe@company.local is listed first in the shortname field of the Domino Directory and enable exhaustive lookups.

  3. We had a similar issue with external recipients seeing the internal address. We had to remove all Notes format addresses (First Last/NotesDomain) from our personal contacts and DA.nsf and replace them with Internet format addresses.

  4. @Sjaak yes I did set it.
    @Shell will check the listing of the user name, but it worked perfectly fine prior to the 852 stream and still works fine in iNotes.
    Exhaustive lookups, will check and try it.

  5. Couldn´t it be a 3rd party component? Like IQ Suites Crypt Module or something else like AV?
