Bioequivalence and Bioavailability Forum

Dear all,

Micro$oft recently changed their system of classification of e-mails.
For reasons I was not able to trace yet, e-mails sent by the forum were rejected (classified as junk):
Final-Recipient: rfc822; foo@hotmailcom
Action: failed
Status: 5.0.0
Remote-MTA: dns; mxN.hotmail.com [65.54.244.NNN] Diagnostic-Code: smtp; 550 Command rejected for policy reasons.

Affected by this policy are all e-mails send by the forum, i.e.,

• during registration, and
  
• to other members of the forum with a hotmail-account.

Temporary fixes for:
New users
If you have a hotmail-account and do not receive your activation e-mail within 5-10 minutes, the blocking was in operation.
Please register again with another e-mail address.
Registered users
If you want to continue receiving e-mails from other users and/or want to be notified about replies to your posts please change the e-mail address in your profile.
Your name (top right hand corner) > Edit user data > [ Change e-mail address ]

I'm trying to resolve this issue and want to apologise for any inconveniences.

Update 2007-01-06
To be classified by Micro$oft as a spammer was for free, but to be put on a 'Whitelist' costs at least 400$...

Quoting Micro$oft following procedure may help:

Q. I received an e-mail in my Junk E-Mail Folder that wasn't Junk. What can I do?
A. To help prevent messages from specific senders from being evaluated as junk e-mail, you can add the senders to your safelist.

If you're using MSN Hotmail:

1. Click Options.
   
2. On the left side of the page, click Mail, and then click Junk E-Mail Protection.
   
3. Click Safe List.
   
4. Type a domain (i.e., bebac.at) from which you always want to receive messages, and then click Add.

If you're using Windows Live Mail:

1. Click Options.
   
2. Click Allowed and Blocked Senders under Junk e-mail
   
3. Click Allowed senders.
   
4. Type a domain (i.e., bebac.at) from which you always want to receive messages, and then click Add to List.

I am not sure whether this procedure resolves the issue, therefore I would still suggest to avoid Hotmail-Accounts for the forum.
