[imp] IMP, Outlook and Hotmail

Sun Apr 20 14:32:19 UTC 2008

Hello,

I browsed the list and googled the net, I know this has already been discussed a lot and th e official position is «this is not MUA problem but hotmail problem » , BUT :
- My configuration is a public internet mail server running postfix + cyrus imap
- Relaying using SMTP is denied except for localhost and my public IP address
- Relaying using SMTP is allowed when user is AUTHentified over TLS.
- Horde/IMP is running on the same server

When I send a mail from outlook to hotmail address, mail is sent through my server (elaying is OK since I’m AUTHentified) and I receive it in my hotmail mailbox
⇒ No DNS, postfix configuration… problem from my server or address
When I send a mail from IMP to hotmail address, mail is silently discarded.
When I send a mail from hotmail -> my address and reply to this mail from IMP, I receive it in my hotmail mailbox
⇒ I think problem is the way IMP forges e-mails (headers ?)
I ***know*** this is a problem from hotmail, not from horde/IMP nor my configuration.
But today, hotmail is a « de facto » standard…So, if anyone want to have a look on this, here are the infos  

Mail forged from IMP and sent to hotmail (CC myself so that I can receive the mail since hotmails silently discards it) :

Thanx a lot for any help you could provide, and go on, I have been using Horde since a long time, it rocks :-) and it’s becoming better and better
