8.4 -> 8.6 results in webmail issue

[suzerain]

Hi there:

I just updated 8.4 to 8.6, and now if I visit http://webmail.domain.com, I get pushed to the web site instead of being shown the webmail interface. Likewise, connecting to mail.domain.com from Apple's Mail.app results in being pushed to the web site.

Any ideas what would cause that?

Hello

Please check that webmail.domain.com has A record in Plesk CP > Domains> domain.com > DNS settings.
It looks like currently it is set as CNAME.
Also try to run
/usr/local/psa/admin/sbin/websrvmng -a -v
