Cannot create data socket (127.0.0.1, 4558): Address already in use



Hi,

We're using Sendmail 8.9.3 and HylaFAX 4.1b2 on a RH6.1 Linux box as a
mail to fax gateway. Occasionally mail to the gateway is bounced with
the following error:
faxmail: 425 Cannot create data socket (127.0.0.1, 4558): Address
already in use...
554 hylafax@012-3456789 fax... unknown mailer error 255

How can I make sure this error does not occur? Is it a configuration
error in Sendmail or HylaFAX or a bug? Is it absolutely necessary that
the data socket always is on port 4558 rather than an arbitrary free
socket? Would a passive connection solve the problem? If so, where can I
find some documentation about this feature?

Thanks in advance for any help!

Regards,
