Topic: Mail client can’t connect to smtp server

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 1.0
- Deployed with iRedMail Easy or the downloadable installer? No
- Linux/BSD distribution name and version: Ubuntu 18.04
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro? No
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

When I try and set up an email client for imap,
(following these instructions https://docs.iredmail.org/configure.thunderbird.html)
the client validates imap over port 143 with Start/TLS. It then tries SMTP over port 587 with Start/TLS and after much spinning finally says it’s unable to reach SMTP server. I am using full email as username, have tried IP address as well as server name. I have attempted to read logs, but I am very new to this and I don’t understand the log outputs.

IRedMail is running on AWS ec2 instance. The security group has an inbound rule to allow port 587. RoundCube webmail sends and receives email fine. I’m using a LetsEncrypt cert. I have tried Thunderbird, Apple Mail, & Canary. They are all unable to connect to SMTP. Thank you for any help.

Re: Mail client can’t connect to smtp server

Additional info:

I can telnet from my local computer to ec2 instance running iRedMail on port 587.  

telnet my.ip.address 587

returns

220 mx.mydomain.com ESMTP Postfix

Watching 

tail -f /var/log/mail.log

I instantly see the telnet connection.

When mail clients attempt to connect:
Watching 

tail -f /var/log/dovecot/imap.log

I see the imap connection.
There is nothing in /var/log/mail.log and email client says unable to connect to SMTP server.

I am using username: mail@mydomain.com (full email address)
Password is copy paste from password manager, not miss-typed.
Host, I have tried both: mx.mydomain.com as well as my.ip.address
Security is Start/TLS port 587

Since I can Telnet to port 587 and get a response from Postfix it seems clear that iRedMail install is working properly and I'm doing something wrong on the client end, but I really don't understand what.  I think I'm entering info exactly as it should be but the email clients do not ever reach my iRedMail server.
Thanks for any help.

Re: Mail client can’t connect to smtp server

I just had similar symptoms although I'm not sure if your problem was like mine.
I was setting up Thunderbird and tried to send mail too many times with wrong credentials, so I locked myself out courtesy of fail2ban.
I did "sudo iptables -L -n" and saw my IP among other culprits.
Then I did "sudo fail2ban-client status" to get a list of jails.
After that i did "sudo fail2ban-client set postfix-iredmail unbanip my.IP.here". The other jails didn't have bans set for my IP, which I found  out haphazardly by trying all of the jails. I wish I knew how to unban all jails for a given IP.
More details here: https://bobcares.com/blog/fail2ban-unban-ip/

Re: Mail client can’t connect to smtp server

Thanks for the suggestion. I just checked and fail2ban hasn’t banned anything yet.

Re: Mail client can’t connect to smtp server

If telnet is reachable, then other MUAs are expected to establish the connection, and client IP is not banned in fail2ban.
Clueless...

- Please stop fail2ban on first, and try again.
- Did you restart the MUA and even the (laptop) system to try again? (yep, a stupid move, but who knows... we need to try all possibilities)

Re: Mail client can’t connect to smtp server

Re: Mail client can’t connect to smtp server

I just retried and MUA complained

insecure SMPT certificate

I am using a LetsEncrypt cert.

Re: Mail client can’t connect to smtp server

MUA gave me the option to use “Insecure” key. I set up the account and send and receive mail fine.
Is there a problem with my LetsEncrypt cert? How do I turn Fail2ban on without locking myself out?  Thanks for your help.

Re: Mail client can’t connect to smtp server

Now I’m really confused. After sending and receiving several email through MUA testing filters, sending through MUA has stopped. No more activity in mail.log. I rebooted server and reissued command to stop Fail2ban and tried again.  Imap is connecting, but no more activity in mail.log
mail.log output

I deleted and reinstalled MUA. Back to original problem. Connect to imap port 143 no activity on SMTP PORT 587, MUA just says “can’t connect to server”. I have restarted and stopped Fail2ban to make sure it was stopped.

Re: Mail client can’t connect to smtp server

Fixed the most recent issue. VPN got in the way. That is sorted out so the only lingering issue is Fail2ban blocking me, so it is currently off, and the MUA complaint of an insecure SMTP cert.

Fail2ban is a hardy beast. A simple stop of fail2ban.service may not be enough. I'd rather try unbanning jails as described above.

It looks empty to me?

Re: Mail client can’t connect to smtp server

- just stop fail2ban for testing, it will make testing easier if you didn't pay attention to it.
- do you have VPN setup on this server or MUA side?
- the maillog and imap.log looks fine, i have no idea why MUA doesn't work. sad

Re: Mail client can’t connect to smtp server

VPN definitely gets in the way, blocks port 587. I just turned Fail2ban back on and so far everything seems to still be working. Enjoy the coffee!
