-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have just located a large source of problems with our installation. We average about 500 POP3 logins per minute and we had roaming users enabled. It seems that writing to the /usr/local/vpopmail/etc/open-smtp file was a large bottleneck since so many logins were attempting to write to the same file. Users would get "file busy" errors while successful logins, when they happened, would take upwards of a minute. Failures would happen instantly, since the file was not written to.
Has anyone found an alternate solution to this? I now use authenticated SMTP only for this installation. Perhaps a directory of entries instead of a file, or some kind of file-based DB? Any ideas? We'd like to keep this feature, but with so many users, this seems to be the only system bottleneck on this system (about 13,000 domains). - -- [!] Justin R.
