Mailx fails when ".com" is specified in email body

Shell Programming and Scripting

Hi

Below works and I do receive the email.

 
 echo "Unable to send file as attachment as File Size is too big i.e. more than 35 MB. Please download from user1@myserv0131:/web/admin/email/serv0131.mybank" | mailx -s "Attachment too BIG | download from the server" mohtashim@gmail.com

However, the below fails and I don't receive any errors or emails.

 
 echo "Unable to send file as attachment as File Size is too big i.e. more than 35 MB. Please download from user1@myserv0131:/web/admin/email/serv0131.mybank.com" | mailx -s "Attachment too BIG | download from the server" mohtashim@gmail.com

The only change is the ".com" string to the email body.

Can you please help me with a fix / solution to this problem ?

Either on the sending side, more likely on the receiving side, this mail is considered spam. As a first step, I would for testing use a destination address where you are sure that no spam filtering takes place, and see whether the mail arrives there.
