email settings. (General)
Yes I am getting back into the eMailing of stuff.
I can tell you for sure, that the IP of the sending eMail server has to match the DNS entry for the eMail server. You can get around this by using the field REPLY-TO: for your main eMail address, and the FROM: for the address on the sending server.
I am having simular issues, I want to send out eMails and have it look like they are coming from a particular user. This way that user will be informed when the eMail fails to be delivered etc. Does SQL Ledger just use the defaults of sendmail when sending to a SMTP server? Can sendmail accept multiple senders (ie the eMail is being send from SQL Ledger on the server, but the return could be one of several people.)
