Hi
Is it possible to change the default value of the email blocksize (1000) and step (0)?

Yes. Make sure to enable the permission for this feature and you will see two new fields for these values if you want so send a mailing.

Just tried it with blocksize 1 and stepping 5 and a mailing list with my own email addresses: I got one mail every 5 minutes.

ive made next test:
add new 100 recipients and start mailing with 1 mail and 5 min.
Weird results - 49 mails sent in one min and now it sent 1 mail per 5 min.
I think it may be cause 70% of recipients sitting in same mailhosts like gmail.com, live.com, etc.
it happens cause sendmail can send many mails in one connection. how can i limit to send one-host mails?
update:
second test
870 new recipients. Sent with 50 mails and 30 min
result: 870 mail sent in one minute
