Unable to send mail with 'mail' command
 
I am unable to cause the 'mail' command to send mail from my linux ubuntu 15.10 computer. File 'mail.log' typically reports "Connection timed out".

Specifically, the log reports:
Jan 5 12:29:53 pegasus postfix/smtp[9006]: connect to mx01.gmx.com[74.208.5.27]:25: Connection timed out
Jan 5 12:30:23 pegasus postfix/smtp[9006]: connect to mx00.gmx.com[74.208.5.4]:25: Connection timed out

I suspect that my ISP (verizon) is blocking port 25 and thus causing the problem: however, I have been unsuccessful in trying to change the smtp port to either 465 (as Verizon recommends) or 587 (as others recommend). Following is my master.cf file:

Are you doing direct-to-MX or smart-host through smtp.verizon.net?

I really don't understand your question. I just issue the command: 'mail -s "my subject" recipient@domain.com < filename', where 'filename' is a file containing my message.

As far as I know, I'm using smtp.verizon.net
My main.cf file contains the line;
relayhost = [smtp.verizon.net]:465
