Outgoing to mail.sonic.net via port 587+STARTTLS with a relatively small attachment (1.5M jpeg, 1.9M after encoding) will consistently fail due to SMTP timeout, yet the same attachment sent via port 465+SSL/TLS goes through.
Any primary guidelines for using one over the other?
General attachment size guidelines?
Cheers,
Tim.
