It seems the current code doesn't allow for removing the email address
from the contact field. This fixes that. This only removes the email
address if an explicit empty email address is specified on the command
line or in the account.conf file. If it is left unspecified on the
command line it still just uses whatever was configured in the
account.conf.
Since some Months, its no longer possible to add TXT Records with the Name "_acme-challenge" to the base domain.
To override the fallback value, you must use a CNAME and proxy it.
For example.
CNAME _acme-challenge.yourdomain.com => proxy_acme-challenge.yourdomain.com
The TXT Records have to be created on proxy_acme-challenge.yourdomain.com
Since the default CNAME TTL is 3600 seconds, it is recommended to leave the CNAME record.
But if you would like to use the build-in SSL (for your web-site etc.) from one.com, you have to delete the record.
A new variable "ONECOM_KeepCnameProxy" you can set in the account.conf is used to keep the CNAME record.
By default the CNAME record will be removed.
For ex.: SAVED_ONECOM_KeepCnameProxy='1'
to keep the CNAME Record and speedup the process.
