Our office has QuickBooks 2011. We have recently started testing with the Thunderbird email client. The email configuration for QB give choices of Web Mail and QuickBooks E-mail. Our mail server is a self-hosted IMAP server, so I've picked Web Mail (even though it's not really webmail). I've selected "Others" as email provider (choices are Gmail, Yahoo, etc.) and put in the correct server name and port. See image, "Edit Email Info".
When I try to send a form, it prompts me for the password, repeatedly, but fails to send the message (see image dialog marked "Email or Password is Incorrect"). On the mail server side I eventually (several seconds) get the message:
Feb 5 12:45:22 mail sm-mta: u15HhrrI001982: COMMON.hprs.local [192.168.0.58] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
In fact, this seems to be a rather silly restriction. Do all businesses who are QB customers really only use Outlook or gmail/yahoo for email? My smart phone can connect to our server! What's up with Quickbooks? All that's needed is an ID, password, server and port. Seems like QB has been over-engineered in this area and results in the elimination of lots of mail servers. Do more recent versions of QB fix this?
If there is no solution to this problem on the QuickBooks end, our solution will be to use something other than Quickbooks.
