Subject: Error message for SMTP Authentication

The following is showing up in our logs and I'm not sure what the error implies:

12:06:10.240 4 SMTPI-856048([]) cmd: AUTH PLAIN <redacted>
12:06:12.335 4 SMTPI-856048([]) rsp: 532 access from your network is restricted, try later

and then a few minutes later, after typing in the password again, the customer gets this:

12:21:26.341 4 SMTPI-860670([]) cmd: AUTH PLAIN <redacted>
12:21:26.342 4 SMTPI-860670([]) authenticating: CLRTXT * <password>
12:21:26.342 4 SMTPI-860670([]) authenticating: AUTH PROXY <redacted2>
12:21:26.343 2 SMTPI-860670([]) '' linked from []:50537

There were no modifications to the account between those connections.  At the client end, credentials were re-entered, but the <redacted> part looked the same.

Any ideas what "rsp: 532 access from your network is restricted, try later" means?

Thank you.
