Issue Postfix doesn't send e-mails outside localhost

Ivo

Basic Pleskian
Hello

We have plesk 12.5 upgraded to latest version, last week we noticed an issue with postfix.

Every mail sent outside localhost was stuck in mailq with following error
connect to something.com[19.29.89.26]:25: Connection timed out).
Doesn't matter if I sent to gmail,hotmail, yahoo or some site error is always the same and mails just stand there in mailq.

Receiving works normal and sending to domains on same server works also.

I have disabled plesk firewall, reinstalled postfix and tried some workarounds found in your faq https://kb.plesk.com/en/124546, or using /usr/local/psa/admin/sbin/mchk --with-spam.

None of that helped.

Any idea where should I check next or what should we try? Or why it worked fine for 1 year and started going berserk last week.
