Why do you have such ridiculously low error limits?
Why are there ANY errors at all from Roundcube? It is supposed to
be well-behaved software.
For the crap client, if they won't fix the client, and you won't
fix your error limits, you can configure a different SMTP service
in master.cf on a different IP address or port.
On a different IP address:
master.cf:
1.2.3.5:smtp inet n - n - - smtpd
-o smtpd_junk_command_limit=some-huge-number
-o smtpd_hard_error_limit=some-huge-number
-o smtpd_soft_error_limit=some-huge-number
On a different port:
master.cf:
:2525 inet n - n - - smtpd
-o smtpd_junk_command_limit=some-huge-number
-o smtpd_hard_error_limit=some-huge-number
-o smtpd_soft_error_limit=some-huge-number
