hi, generalized question about Tor exit relays and exit relay operators. do some exit relay operators have a policy to prevent connections leaving their exit node via non-encrypted ports (e.g. port 25)?
this could be a philosophical position - not even wanting to be in a position to observe users' data passing through the exit node in clear text. or a pragmatic position - hoping that encrypted connections provide some level (even very weak) of plausible deniability in the event that a connection attracts the attention of law enforcement. this is just my thoughts.
Hi !
SMTP ports are often used for spamming so that's why most exit relay operators blocking them.
Spamming from your machine = abuse reports = potential suspension of your service by provider

Although the intent of your statement is understandable, ports themselves are not "encrypted" or otherwise. The traffic commonly carried on them could be of a protocol that is such. Also remember to consider protocols like SMTP on both ports 25 and 587 will commonly start as plaintext and elevate through the use of STARTTLS.
