Hi, due to no response to my mail some days ago, I should specify a little more my situation.
Topology looks like this: Internet gateway (relay secure - non - Exchange) delievers to a Exchange machine 5.5 Sp4 NT4Sp6a hotfixed receiving mails for *.domain.com and domain2.com (its own domain is domain.com) It's the only machine with internet access. connected to this are 3 other machines, 2 with sub1.domain.com and sub2.domain.com, the third with domain2.com The 3 machines are connected via IMC, all is in one organisation with 4 sites. Now when i have setup routing restrictions on the main machine to secure it from the internal side, I see that relaying to sub1.domain.com and sub2.domain.com works fine - these machines can send and receive mails. The third machine with domain2.com can send well but when receiving a mail from external, I see a 550 relaying denied and the mail is blackholed somewhere. Any idea from the relaying and routing freax? Thx in advance Steffen _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
