Does anyone have an idea why pf and/or smtp protocol behave in such a way, and how this could be solved? If it is worth, I am connected via adsl. The rules that I wrote have been discussed here a million times - just a standard set of rules that work for all but smtp. Oh, by the way, I can ssh into this mail server from outside without any problems. So, it is only the smtp issue.
Troubleshooting this without seeing the entire ruleset is just guesswork.
