Like I described
above, I've used the ASPMail component from Server Objects for a number of years
on both Planet Source Code and Rent a Coder. I've used it to send out over
a hundred thousand emails a day, and until recently had absolutely no complaints
about it (except that it was sometimes a bit slower than I would have liked).
However, recently I ran into
a HUGE gotcha with it, that everyone should know about. About a week ago,
people on the Rent a Coder mailing list people started complaining that they
weren't getting their newsletters. The program wasn't bombing, so I was stumped
After investigating further, I
discovered that ASPMail was returning an odd message "paragraph too large"...and
simply not sending out the message. My message was over 138,000 bytes (due
to the growth of new bid requests on Rent a Coder) and by doing a little
experimenting I found that messages about 123,000 bytes or so would cause this
I hunted up and down
the manual for a way to get around this limitation but found nothing. I
also sent an email to ASPMail support, but as of this writing has not yet
received a reply.
Since the show had to go on, I
searched the NET for another SMTP component without such a limitation and found
an interesting replacement. Software Artisans (best known by ASP
developers probably for SA-FileUp...a file uploading component) also develops an
They must be gunning for
Server Objects, because the interface for the component was exactly the
same as ASPMail! What this meant for me was that it took seconds to switch
to it: all I had to do was change the CreateObject to the new ASPMail defenition
and it worked like a charm!
The Software artisans SMTP
component didn't have the limitation and is actually a bit faster, so at this
point I'm happy to have made the additional investment and made the switch (it
was about $125).
If I run into problems with
this component, I will be certain to keep you apprised!
