RE: Sending very slow

Chip,

I did further work and timing for sending of emails seem to have improved a lot.

Having achieved a good outcome on the above, my next task is to send a simple short text message like, “RSAM ALERT NOTIFICATION – Ulawun”, to a cell (mobile) phone number.

I read the blat commands but could not find one that does it. Is there any easy way for doing this..

Thanks.

Ima.

Ima,

The 180 KByte attachment size should not be a problem because most mail
servers now support messages well above 1 MByte, many servers support more
than 20 MB message sizes. Which image format to use may depend on what
image quality you want. Otherwise, it should not matter. Experiment with
the different formats, and look at both the quality of the original image
and file size.

Are you saying that it takes Blat itself more than a minute to send
messages? If this is the case, that is because the SMTP server is really
slow.

If you mean that it takes more than a minute from when an email is sent
until it is received by the recipient, that could be explained by a number
of reasons. One reason for slow delivery could be anti-virus scanners at
either or both servers, and/or at the client computer.

When sending to Gmail accounts, Google does additional processing on inbound
traffic that delays delivery.

If you are using a list of email addresses, and telling Blat to send emails
to each address one at a time, then that will take much longer than if you
could send an email to a group of email addresses at once.

I do not think you are doing anything wrong, it could be just how the mail
servers are configured that make it all seem slow.
