Hi everyone!
For start, here is my infrastructure:
1 HAProxy which proxy POP, IMAP, HTTPS connections to CAS.
3 CAS - 2013 CU21 (CAS1.HQ.PHARM.COM, CAS2.HQ.PHARM.COM, MAIL4.HQ.PHARM.COM)
2 MBX - 2013 CU21 (MBOX1.HQ.PHARM.COM, MBOX3.HQ.PHARM.COM)
Few days ago i've noticed that our CAS servers got many errors with code 46. After some surfing, i found that it could be caused by incorrect TLS certificate settings. So i've checked everything at least twice:
1) All servers have wildcard cert installed with name *.pharm.com.
2) Cert assigned to IIS, SMTP, POP and IMAP services on all CAS servers.
3) Cert assigned to "Default Frontend" and "Client Frontend" connectors for all CAS servers with set-receiveconnector command.
Mails are going fine, and we dont have any problems with authorization. I'm running out of ideas about what this errors could be caused by, only guesses:
1) Сould this be due to the fact that the name of main certificate is *.pharm.com, and name of servers *.hq.pharm.com?
2) May this be caused to incorrect settings in Default Frontend and Client Frontend receive connectors?
3) Can this issue be related to mbx?
Please help!
