We've got a BT 'static' IP address for our Kerio Server. Anyone with any British Telecom experience will know that this 'static' address does not have a valid reverse dns value, so the likes of AOL reject any mail coming directly from our system. Is there any secret way that anyone knows of to add a 'smarthost' so that any mail for AOL (for example) gets sent through a proxy smtp rather than directly using DNS/MX records. Any other work arounds would also be welcome.

Many thanks in advance.

you could send all mail thru mail.btconnect.com which is an smtp auth relay host. you need to contact them first and get your domain authorised.

apart from that you are looking for postfix like transport domain settings which KMS does not support AFAIK.

yep

either use BT's relay (you will need to login to the portal and fillin the form to authorise your sending domain name)

alternativeley you can buy access to many third party smtp relay services for a few dollars a year...

Yes, i have access to my own Authenticated SMTP server, but I don't really want to use it for the sake of one domain!!!

I like the DNS delivery method.

i know what you mean but you are going to find more domains that will behave this way.....

this is a short list

  • aol
  • hotmail most of the time
  • barclays
  • dell
  • fsworld
  • pobox.com
  • o2
  • btinternet

Phil.

Not sure what you are asking for!!!

You said you wanted a smarthost & now you have some suggestions you say you "like" using direct MX.

What would be the point of having 2 parallel delivery methods!!.

This seems like unnecessary work to maintain smarthost delivery for just a list of domains which you cannot SMTP direct to!

I said i like using DNS delivery but would like the option to be able to pick out particular domains to use a different transport like Exchange can. All I'm trying to avoid is the occasional problem with passing SMTP on to another server which is out of my control so not knowing immediately if they are having delivery issues (admittedly this is quite rare with the provider I use). Also, I like to keep my bandwidth usage down through this provider, and would prefer to use my unlimited bandwidth available with my BT Business connection.

Still sounds like a waste of energy to me

In any case you can't do it.

You could always register with support<_at_>kerio.com as a suggestion.

Who knows they implement it by about KMS V9
(I have had several suggestions on the list for over a year myself!!!)

there is a use for this......

if you havea complicated interbal structure for your mail then you might want to use multiple "transports" to route mail to specific mail hosts for them to deal with.

also when sending externally you may want to send internally oner a private link when it is available depending on your lan/wan infrastructure.

its great for test environments and complicated setups that need more than just straight dns or smarthost.

Yes - but this is not what Phil wants it for...!

Sounds to me like the way to implement is to have options for 'local' & 'remote' when creating domains with delivery methods set individually.

Like I said you could suggest it to Kerio - Good Luck!!

You can set forwarding for a domain so that any emails go to the server you specify for the domain. I think I have seen this mentioned before on the forum, and I also think it is in the manual. You just create the domain and set the parameters for where you want the emails to be sent to. I haven't tried this myself so can't comment on how well it works.

The only problem is that you cannot set smtp auth for a connection like this.

Actually there are 2 problems

1)You can't SMTP Auth (So would have to use BTConnect & register your domain on their list)

2)You can't set a domain to send to using Direct MX

Definately not ideal is it? I suppose what is required is something like the Connector in Exchange with more options for what to do with a particular domain? Who knows, maybe the mythical 6.1 has it already, but i'm not holding my breath.

Me Neither....

The (alleged) panacea of 6.1 has been built up so much it can now only be a disappointment

Now if it had been released last year as planned maybe we would have got rid of the bugs by now..!

yes I know thats why I suggested the "correct" answer earlier. I was responding to two of your comments which I should have quoted I know......

I was trying to answer this statement

and this one

but I agreee that this should go with the other suggestions......

However it is a limit of the functionality of kerio as an enterprise mailserver and should be addressed at some point. Its not a big concern of mine since I will use postfix when faced with these situations.
