# SMTP a security problem?

 * Hi, I just installed your plugin and everything went perfectly. My website’s 
   outgoing email immediately started landing in people’s inboxes rather than in
   their spam folders.
 * But since I’m a novice at these matters and don’t know SMTP from RSVP, I did 
   some reading on SMTP, and on one website I came across made this statement:
 * “Another strategy that hackers use: If your app sends email using SMTP, the IP
   address will be recorded in the Received header lines. Either scrub the original
   Received line [no explanation provided of how that’s done], or don’t use SMTP
   for email submission.”
 * Is this something I should be concerned about security-wise? Or does your plugin
   solve this problem somehow? And if not, how should I fix it?
 * Thanks!

 * Hi, Gmail SMTP plugin is using this method to connect to the SMTP server (There
   is no other better method to access the Gmail API).
