Catch ALL "means" catch **** too, bad idea!
Mr. Comptalk
An email catch all means that any email address not already defined will be caught and dumped into the email address defined to receive the catch-ed all email. This includes imaginary friends and family names of people you dont know, even with unusual spellings like frannk, suszin, bobby32 and any number of mixed irregularities. I bring this up because I have been bombed a few times on my domains where the person doing the bombing simply randomized the names with letters and numbers and sent me thousands of emails in the course of a few hours. After deciding they got through, they bombed me again. Since they randomized the addresses, it was impossible to block each name. The solution to the problem was to create aliases for the catch all email address by creating the email address to be used and then inside clicking add alias and entering the names I believed would receive email and would have come to that trapped address. By doing this, in this fashion instead, two things occurred. One, the addresses that I wanted to catch and only the addresses I wanted to catch get caught and Two, any addresses NOT defined are automatically kicked out unprocessed by Plesk (version 7.x) and reduces the over all waste load on the server caused by spam (and idiot bombers).
Spam is also a worry with using a trap all address. Spammers will randomize email addresses (as in combine common names with known domain names) to hit users that may not have posted somewhere subjecting themselves to this kind of abuse.
So my advice here is, do not use a trap all, there are other solutions such as aliases that will work much more safely.
