Duplicate emails running fetchmail

Hello, I have a problem, I am currently using fetchmail to retrieve my
emails from two accounts, one gmail.com, another corporate one with
POP3.

This is my fetchmailrc file:
poll "pop.gmail.com" with proto POP3 port 995 user "[email protected]"
password "xxxxxxx"
sslfingerprint "xxxxxxxxxxx"
no rewrite keep ssl fetchall mda "/usr/bin/maildrop"

poll "mail.xxxxxxxx.co"
proto POP3
port 995
user "[email protected]"
password "xxxxxxx"
sslfingerprint "xxxxxxxxxxxxxxx"
no rewrite
keep
ssl
fetchall
mda "/usr/bin/maildrop"

In the first execution I use it in the following way, and I invoke it
inside mutt with the macro "G"
macro index G "!fetchmail\n"
macro pager G "!fetchmail\n"

My problem comes when I enter mutt again and invoke G to activate the
daemon (for the second execution I make these changes in my file:)

set daemon 60
poll "pop.gmail.com" with proto POP3 port 995 user "[email protected]"
password "xxxxxxx"
sslfingerprint "xxxxxxxxxxx"
no rewrite keep ssl nofetchall mda "/usr/bin/maildrop"

set daemon 60
poll "mail.xxxxxxxx.co"
proto POP3
port 995
user "[email protected]"
password "xxxxxxx"
sslfingerprint "xxxxxxxxxxxxxxx"
no rewrite
keep
ssl
nofetchall
mda "/usr/bin/maildrop"

and I recover but this duplicate the messages, does anyone know if
there is any option for this not to happen? I change previously to
notfechall but even that way it brings me duplicate emails.

Thank you in advance for your help.

Regards,
