    SendSMTPCommand: Timeout waiting for response after 15 seconds.

    We use postini to route incoming mail through their servers first before we being delivered to our mail server.  right now our mail server is setup to send directly out and not through postini outgoing servers.

    We are running exchange 2007 sp3.

    on my outgoing send connector in the EMC the fqdn shows as: mail.mycompany.com

    mxrecords:
    mx:mycompany.com


    Pref     Hostname     IP Address     TTL     
    10     mycompany.com.mail5.psmtp.com     60.18.5.1     2 hrs     Blacklist Check      SMTP Test
    20     mycompany.com.mail6.psmtp.com     60.18.5.2     2 hrs     Blacklist Check      SMTP Test
    30     mycompany.com.mail7.psmtp.com     60.18.5.3     2 hrs     Blacklist Check      SMTP Test
    40     mycompany.com.mail8.psmtp.com     60.18.5.4     2 hrs     Blacklist Check      SMTP Test

    our dns is managed through network solutions. We changed our ISP awhile back to PAETEC now windstream. i have contacted my current ISP and they gave me an email address to send my request to update my PTR record. I thought that it should be mail.mycompany.com (the same that is my fqdn of my mail server). Would that PTR record update resolve my issues that mxtoolbox is pointing out to me in the tests above?
