We have a customer that has a qmail installation and is using passwd for authentication. I would like to migrate them into our qmail installation and have their domain setup in vpopmail...about 3500 users. We have vpopmail setup (using vpasswd for users) on this particular box, but don't have any virtual domains with anywhere near that number of users. Is that too many users for a virtual domain using vpasswd or would vpopmail/mysql work better?
One box I look after has 20K+ users in a cdb file, no problems if you aren't updating the vpasswd file more than once a minute. MySql is better but it won't be a problem if it isn't being updated all the time.
Looks like I can convert the passwd/shadow file on the old server to vpasswd using the vpopmail vconvert program included with vpopmail. Is there a better way?
Nope, that works quite well and quite fast.
On the old server the Maildir is located at /home/username/Maildir. Once the domain is setup via vadddomain on the new server and the vpasswd file is created with vconvert, is it just a matter of moving the user directories in the /home directory from the old server to the new vpopmail virtual domain and setting the vpopmail permissions?
Yup, a copy will work just fine, remember to chown -R vpopmail:vchkpw * afterwards.
