No such thing as "too wordy" when asking for advice. In fact, the problems
I'll have in responding are more related to what you didn't say than to what
you did say. Preliminary ***guess***: all of your problems are caused by a
full filesystem, either / or /home . If they are, your only solution is to
make some room on the full filesystem, either by deleting some stuff or
moving part of it to a new filesystem ( = new disk partition).
Error messages with ambiguous context are hard to interpret, as are
fragmentary ones (in at least one case, the message obviously went on, but
probably your screen didn't do linewrapping so you didn't see the rest of
it). Also, it's helpful to include basic information about your system --
always, which Linux distributio, which version, and which kernel version
("uname -a"); in this case, the sizes of your hard disks.
With that disclaimer ...
To receive SMTP mail, something needs to be listening on port 25. You know
the way to check that; you did it right. You should have done it again after
the reboot, to see if some daemon was started. There are other ways to check
this, but the one you're using is the easiest and most certain.
To send SMTP mail, you don't need a daemon running. Your MUA (e.g., pine)
just needs to be able to start the MTA (e.g., sendmail) it knows about.
Three things about the error message you quoted:
1. Was this message onscreen or in a log file?
2. Error messages usually open with the name of the program that procuced
them. I'm guessing that what you saw actually read: "sendmail: Mail not
sent....", but you need to be specific about that (NEVER leave out ANY of
the words, even the ones you think are unimportant).
3. It's the incomplete one I referred to above.
It's possible that this message, if complete, sould have said something
like: "Insufficient space on /var/spool/log", but that's only a guess. In
any case, the way to check filesystem utilization is with the command "df".
You will have problem is the filesystem with the mail spooler is full
(that's usually /var/spool/mail), or if the one with the user's home
directory is full (usually /home/userid), or if the one with the scratchfile
directory (usually /tmp) is full.
For more information on the commands I've mentioned, use the man system --
e.g., enter "man df" to learn more about the df command. "man man" will
introduce you to the man system itself.
