Wise to block port 25 & 26 (for email)

I login & send email through thunderbird using SSL and it's ports (so I no longer connect using 25/26). Occasionally I use webmail (Squirrelmail)

My scripts do send mail via sendmail.

Does my cpanel server still need the basic 25 & 26 ports to deliver and receive mail successfully, or can they be blocked in APF without any problems arising?

Port 25 is necessary for your server to receive mail from other mail servers.

Especially, if you're to receive bounced mail...
