Can't send email with large (over 1MB) attachment

Win 7 64-bit, Thunderbird 31.2.0, eSet antivirus (but disabling it for email doesn't help), godaddy email server (works fine from godaddy web mail), port 80 (been using this port for years; 25 doesn't work)

Sending email with a 974KB attachment works. Email with a 1.4MB (and larger) attachment doesn't work. The error message appears pretty quickly (5 seconds at the most).

The message is "the connection to SMTP server smtpout.secureserver.net timed out".

This problem seem to appear at random, then go away and all is well (for a while).

do you have an older modem perhaps?

No. The modem is an Arris obtained from Comcast on 6/9/2014 after the prior one failed.
