That*is* a problem. Postfix will slow down and eventually hang
up when a client sends too many commands that cause an error

To make this robust the verified MUST disconnect after each probe.
When you say 'the verifieD MUST disconnect...', I'm assuming you meant
'verifieR' - meaning, their server, the one connecting to mine sending
VRFY probes?
Thanks, I'm passing this on to their support team.
Ok, I got the following response... is doing as they are recommending an
acceptable way to resolve this issue?
We are set up for performance with VRFY probes and by modifying your postfix
config file so postfix will not nave a performance issue by setting postfix
option smtpd_soft_error_limit to be larger than smtpd_hard_error_limit.
This can be done by setting set "-o smtpd_soft_error_limit=1001 -o
smtpd_hard_error_limit=1000" in his postfix config file.
I'm fine doing this, as long as this isn't going to cause other issues
or have unintended consequences.
Note: my postfix server *only* accepts inbound connections (including
VRFY probes) from their netblocks.
Thanks,
