SSL TLS

Hi, my smtp server require SSL encryption on port 465 and not TLS.
How i configure my smtpsrvs file?
I tried :
1;mysmtpserver.server.com:465;from@mail.it;user@mail.it;password;yes;TLS;0

i receive this error when i test :
Firewall rule SMTPout-465 added...
TLS Module ::: The e-mail server [mysmtpserver.server.com] is not reachable at port [465]
Firewall rule SMTPout-465 closed.

Why?

Re: SSL TLS

The SMTP module first scans the server to check that it is indeed listening on the specified port. If you get that message, then the SMTP client was not able to reach the SMTP server. Check your network, network firewalls, SMTP server firewall, etc...

Re: SSL TLS

i do not have firewall.
if i configure my smtp server in outlook in a vm windows inside esxi i have no problem.
it seems that port 465 is blocked by the esxi firewall

Re: SSL TLS

The SMTP port is opened automatically by XSIBackup in ESXi, as you can read in the program's output. Check other possible causes. If you still suspect it could be the ESXi firewall, you just have to disable it

esxcli network firewall unload

And try again. To enable the firewall again

esxcli network firewall load
