Dear Team,
We have tried to create a email scheduler, We don't have a local SMTP server. We getting the below error,
Please find the packet flow below.
c2s flow: source: 10.1.1.5 [LAN] dst: 172.217.194.109 proto: 6 sport: 56175 dport: 25 state: INIT type: FLOW src user: unknown dst user: unknown ecmp id: 8000 s2c flow: source: 172.217.194.109 [WAN] dst: 182.74.53.90 proto: 6 sport: 25 dport: 64050 state: INIT type: FLOW src user: unknown dst user: unknown start time : Thu Sep 2 14:27:23 2021 timeout : 15 sec total byte count(c2s) : 541 total byte count(s2c) : 700 layer7 packet count(c2s) : 7 layer7 packet count(s2c) : 8 vsys : vsys1 application : gmail-base rule : PaloAlto-Management-Email service timeout override(index) : False session to be logged at end : True session in session ager : False session updated by HA peer : False address/port translation : source nat-rule : Outgoing_Internet-Airtel(vsys1) layer7 processing : enabled URL filtering enabled : True URL category : any session via syn-cookies : False session terminated on host : False session traverses tunnel : False session terminate tunnel : False captive portal session : False ingress interface : ethernet1/1 egress interface : ethernet1/3 session QoS rule : N/A (class 4) tracker stage firewall : TCP FIN end-reason : tcp-fin
Packet flow seems good but still getting test mail error like unable to send mail via gateway smtp.gmail.com

Gmail requires user authentication etc. Check if your ISP has an email relay they make available to their customers
