Ok, so I just add a bunch of entries following this pattern into the "Bulk-Edit Forwarding-Only Addresses" form?
That's simple enough (I wasn't familiar with this functionality), and the fact that all mail for the accounts will go to catchaddress is a bonus.
I notice that the from and to address are separated by two tabs. Is that the required delimiter for these lines?
Also, do you foresee any problems with this strategy given that I will have to reply to activation emails sent to each twitteracct?@mydomain address?
(btw - I read your initial reply as accusatory. That may have been my misperception)
I think that these would need to be permanent addresses. Skipping the one-time upfront effort of creating the accounts would leave me to suffer ongoing incoming spam.
I have all of the account names stored in a database (each is tied to specific audience segments) anyway. So I can create all of these bulk email entries with a select statement, then just paste it into the form
