Hi

Did you try to send it via the command line?

echo "ssmtp test mail" | mail -vs "Test email for SOL13180" myemail@mydomain.com

Hi Patrik

 

Yes i already tried that as stated in my first query . After trying to send a Test mail ; i get the following message

 

send-mail: Cannot open mail:25

 

Note : Telnet to the SMTP server on port 25 happens fine from CLI of F5 LTM .

Have you tried to use tcpdump while running the test to verify that the right ip+port is used?

 

Sometimes the SMTP servers requires white listing of ips allowed to send.

 

Have you successfully sent an email with Telnet as well (ie not only connected)?

are you using fqdn or ip in ssmtp.conf?

if fqdn, you have configured dns, haven't you?

[root@ve11a:Active:In Sync] config  grep something /etc/ssmtp/ssmtp.conf
mailhub=something.somewhere.com

[root@ve11a:Active:In Sync] config  echo "ssmtp test mail" | mail -vs "Test email for SOL13180" nitass@xxx.com
send-mail: Cannot open something.somewhere.com:25

Hi nitass,

 

I have tried configuring both (IP Address as well as FQDN of SMTP server) ; however no success . Also , i have configured SMTP FQDN mapping to IP under System -->Configuration -->Device -->Hosts

 

Considering my mail server is something.somewhere.com , if i try to send a test mail , i get the following

 

send-mail: Cannot open mail:25

 

Hi Patrik,

 

I havent tried sending mail with telnet . Its just that i have used the command "telnet 25 " from F5 Root CLI and got the message .

Also , SMTP Relay server has F5 IP allowed in the whitelist

 

Thanks & Regards,

so, can you try tcpdump (when running echo..)?

via tmm interface
 tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap port 25 -v

via mgmt interface
 tcpdump -nni eth0 -s0 -w /var/tmp/output.pcap port 25 -v

Connected to just verifies that the tcp hand shake works. Try sending an email following this guide and use nitass tcpdump commands above to capture the traffic.

Also like nitass suggested, try sending with:

echo "ssmtp test mail" | mail -vs "Test email for SOL13180" myemail@mydomain.com

And use the tcpdump commands when doing this.
