Sent emails do not appear in gmail sent folder

Dear all,

Server: PHP Version 5.4.45
Smtp gmail

PHPLIST Installations:

  1. (phplist version 3.2.3, operating OK for the past 2 years)
  2. (phplist version 3.2.4, installed last week)
  3. (phplist version 3.2.4, installed last week)

Current: Cron job from sub1 and sub2 (7,500 subscribers each)

Sending is ok, according to log file and phpList Maillist Processing info.

Problem is:

– The emails sent do not appear in the gmail sent folder.

(whereas in the old installation, the sent messages did appear.)

Is there a relative config setting?

Many thanks.
