What is configurable in the Lotus SMTP MTA?
Here are a couple of the most frequently asked questions on this subject: Question: I installed version 1.1 of the MTA but now some mail messages are coming in as a file attachment with an attachment name of “att1.unk”. Answer: The reason is that some mailers inappropriately send messages with a Content-Type of “Plain/Text” (Netscape is the most frequently used mailer that does this) but without a Content-Name; plain text messages should not be specified with this MIME Content-Type attribute. If you want to go back to the way SMTP 1.0x handled it, set “SMTPMTA_INLINE_TEXT_ATTACHMENTS=1” in your notes.ini file.
