How to set up postfix as a relay to an external server?

Question

linux

There is an external mail server. On which there are about 30 accounts. There is postfix on the local network, through which we want to run all letters.
Everything was already working, but the external server changed, it became kerio, the port became: 465. Was :587.
Now this error:
postfix/qmgr[939]: 61EB88018: from=, size=1632, nrcpt=2 (queue active)
postfix/smtp[1020]: warning: SASL authentication failure: No worthy mechs found
postfix/smtp[1020] : 61EB88018: to=, relay=xxxxx[xxxxx]:465, delay=354, delays=354/0.01/0.09/0, dsn=4.7.0, status=deferred (SASL authentication failed; cannot authenticate to server xxxx[xxxxxx ]: no mechanism available)
Here is my main.cf

/etc/postfix/sender_relay - here, respectively, mappings mappings of local accounts and what to send through
/etc/postfix/sasl_passwd - here logins, passwords
Tried to add options, but did not help:
smtp_tls_wrappermode = yes
smtp_tls_security_level = encrypt
smtpd_tls_security_level = may
Directly using smtp and imap the client clings, i.e. the password is correct.

In master .cf
-o smtpd_sasl_auth_enable=yes
