Hi,

I seriously doubt that an email sent with Claws gets rejected by Google,
because it was sent with Claws.

However, don't inform Google that you are using Claws by

  uncheck   Add user agent header

Some providers strip this header anyway.

In addition you could

  check     Add user-defined header

and define whatever header you want instead. Maybe

User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101
 Thunderbird/78.14.0

or

User-Agent: Wanderlust/2.15.9 (Almost Unreal) SEMI-EPG/1.14.7 (Harue)
 FLIM-LB/1.14.9 (Gojō) APEL-LB/10.8 EasyPG/1.0.0
 Emacs/28.0.50 (x86_64-pc-linux-gnu) MULE/6.0 (HANACHIRUSATO)

or

User-Agent: Evolution 3.36.5-0ubuntu1 

or

X-Mailer: PHPMailer 5.2.23 (https://github.com/PHPMailer/PHPMailer)

or

X-Mailer: Formware Mailservice Microsoft CDO

or

X-Mailer: vBulletin Mail via PHP

or

X-Mailer: Open-Xchange Mailer v7.10.5-Rev41

or

X-Mailer: iPhone Mail (19D52)

Just a few I can see in my non-Google inboxes. But again, a lot of
the received emails don't provide such a header at all.

Regards,
Ralf
