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
SMTP trace of email on alert from RTMT:
220 zent.nowhere.com ESMTP Postfix (Ubuntu)
EHLO cucm71
250-zent.nowhere.com
250-PIPELINING
250-SIZE 10485760
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
MAIL FROM:<RTMT_Admin@nowhere.com>
250 2.1.0 Ok
RCPT TO:<jimmy@nowhere.com>
504 5.5.2 <cucm71>: Helo command rejected: need fully-qualified hostname
RSET
250 2.0.0 Ok
QUIT
221 2.0.0 Bye

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.

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
.....
504 5.5.2
