RTMT e-mail alert sender's fully qualified name problem

Is there something else to be configured in CUCM to make it send emails with FQDN os sender? I could disable this FQDN requirements on SMTP server but would prefer to receive FQDN from CUCM in EHLO.

.

Configuration is the following:

admin:show network eth0

Ethernet 0

DHCP         : disabled           Status     : up

IP Address   : 10.1.1.221         IP Mask    : 255.255.255.000

Link Detected: yes                Mode       : Auto enabled, Full, 1000 Mbits/s

Duplicate IP : no

DNS

Primary      : 10.1.1.224         Secondary  : Not Configured

Options      : timeout:5 attempts:2

Domain       : nowhere.com

Gateway      : 10.1.1.1 on Ethernet 0

admin:show version active

Active Master Version: 7.1.5.33900-10 Unrestricted

Active Version Installed Software Options:

cmterm-devicepack7.1.5.33052-1.cop

ciscocm.dst-updater.2010o-1.el4.7.1.5.cop

ciscocm.dst-updater.2011h-1.el5.7.1.5.cop

RTMT e-mail alert sender's fully qualified name problem

I don't think there is a way to set the FQDN in the mail message, such as RTMT_Admin@cucm01.nowwhere.com, the domain name is the only thing that will be added to the from field which you currently have.

RTMT e-mail alert sender's fully qualified name problem

Hi Joe

Actually I meant the name sent by CUCM in EHLO request. As you see, though DNS server and domain name are declared in CUCM only hostname part is sent in EHLO. If I emulate this e-mail with telnet and use EHLO cucm71.nowhere.com then SMTP server accepts this e-mail

....

EHLO cucm71
