Thanks for all your help. But I am still having the problem. I've made the following test:
1. Created a domain foo.com on 'smtp01'. Vpopmail auth works. 2. Removed all entries of foo.com on /var/qmail/users/assign /var/qmail/control/virtualdomains. It still works. 3. Removed the /var/vpopmail/domains/foo.com directory. Not working. 4. Re-create the directory. Works again.
Question: Does vchkpw checks for ~vpopmail/domains structure to validate
It sounds like a possible bug in (I'm guessing) vauth_getpw, and the limits code in particular. I'm guessing that if it can't change to the domain directory, it fails with an error.
I don't think there's any reason to require the directory to be present. I'll take a look at the code and see if I can fix it.
What version of vpopmail were you using? 5.3.30? Are the SMTP connections coming in on port 25?
