Regular Expressions/Wildcards in IronPort ESA Recipient Accept Table

[Cosmin Goea]

Is it possible to define Recipient Accept Table entries using Regular Expressions or wildcards ?

For example, given a very large email address space in the format abc-1xxxxxxxxx@domain.com, where x ∈ [0..9], for which one needs to bypass LDAP Accept, could RAT entries be added like: abc-1[0-9]{9}@domain.com or at least abc-1*@domain.com or it's just literals ?

Thanks. :)

No.  It will not read the entry as a regex for the RAT.

The following formats are allowed:

• Hostnames such as "example.com", "[1.2.3.4]", "[2001:420:80:1::5]"
• Partial hostnames such as ".example.com"
• Usernames such as "postmaster@"
• Full email addresses such as "joe@example.com", "joe@[1.2.3.4]" or "joe@[ipv6:2001:420:80:1::5]"
• Separate multiple addresses with commas.

If the overall number of entries in RAT table would be under 300.000 then you can specify addresses in txt file and import it.

abc-1000001@domain.com

abc-1000002@domain.com

...

ALL REJECT

300.000 entries limit ? Interesting. I didn't know there was such a limit. Thanks.

As suspected. Thank you.
