Hi In the Listserv installation guide it says: <quote> PLEASE NOTE CAREFULLY that if you need a turnkey solution on a single machine, you will have to purchase and install L-Soft's LSMTP mailer, which is the only SMTP mail product for Windows NT/2000/XP that can co-exist on the same Windows NT/2000/XP machine with LISTSERV. </quote> That doesn't apear to be true. That is, I have installed Listserv and the free version of MailEnable on my Windows 2k box and got it working. All that was required was to set MailEnable SMTP to listen on a port other than 25 (since Listserv's SMTP listener occupies that port); then change the SMTP_FORWARD line in Listserv's config so that I specify that port. eg: SMTP_FORWARD=localhost:26 My tests so far haven't found any problems with this at all - OK, Mail Merge wont work, but then it presumably doesn't on *nix installations using SendMail etc. Am I missing something here or is the installation guide misleading?
